Warmy Review (2026): Warmup, Seed List, Pricing and Who It Fits

Warmy is a strong pick if you want one subscription that covers email warmup, seed list engagement, placement tests, verification and DMARC monitoring, and especially if you send B2C or marketing email that most cold email warmers ignore. It is a weaker pick if you run one or two mailboxes on a budget, or if your sequencer already includes warmup. As of November 2026, plans start from $49 a month, and Warmy's own pages disagree on whether that price covers one mailbox or a shared daily volume.

Some tool links here are affiliate links (disclosure). Nerdy Joe is a Warmy affiliate and also a MailReach affiliate, so we earn from both tools compared most closely below. To look at the product first, you can start Warmy's 7-day free trial, which needs no credit card.

Nerdy Joe is a certified Apollo.io Managed Services Partner and a PlusVibe Certified Silver Partner. We did not test Warmy hands-on for this review, and we have no warmup or placement data of our own. Everything below comes from published sources, listed at the end.

Warmy review: the short verdict

Warmy does more jobs than most warmup tools: network warmup, a seed list that engages your real campaigns, placement tests, verification, DMARC monitoring and Postmaster data. The trade-offs are plain. The pricing page shows only a starting price, several of Warmy's own figures conflict, fees are non-refundable under its terms, and it is not a sending tool.

All Warmy prices in this review are as of November 2026. Because the plan table does not appear on the pricing page itself, check the current plans inside Warmy's app before you budget. Our separate Warmy pricing breakdown goes deeper on every plan and add-on.

What Warmy is

Warmy calls itself an email deliverability platform. Its products include Email Warm-Up, Email Seed List, placement tests, Email Verification, DMARC Monitoring, a Google Postmaster integration, an API, AI Connect, the Adeline AI assistant and SendNova (in beta), plus a Reputation Repair service.

It is not a cold email platform. SendNova is a beta workspace that reports on campaigns sent through platforms like Mailgun and SendGrid, and no page we read describes sequences, a lead database or a CRM.

The company behind it

Warmy's terms name Warmy Technologies LTD, incorporated in Israel, as the company behind the service. The terms are governed by Israeli law and were last revised October 1, 2026. We could not verify a founder, founding year, funding or headcount from the pages we read, so we leave them out.

Warmy's customer counts conflict across its own site ("7000+" on several pages, "35,000+" on the Adeline page), so we do not pick one.

Warmy shows a "SOC 2 Type II audit in progress" badge, which describes an audit underway, not a completed report.

Who Warmy is for, and who it is not for

Warmy positions itself for both B2B and B2C senders, with separate pricing cards for each, which is a real difference from cold-email-only warmers.

Warmy is a good fit if:

• You send marketing or transactional email through Mailchimp, Klaviyo, SendGrid, Amazon SES, Mailgun or a similar platform and want warmup or seed engagement there.
• You warm 10 or more mailboxes and want one bill for warmup, placement tests and monitoring.
• You want warmup content by industry, language or your own templates.

Warmy is probably not the right fit if:

• You run one or two mailboxes and price matters most. Warmy's $49 entry is about double MailReach's $25 single-mailbox rate.
• You already pay for Instantly, Smartlead or PlusVibe, which include warmup for unlimited mailboxes in the sending plan.
• You need a firm price list before signing up, or a refund if it does not work out.
• You expect warmup to fix a bad list or spammy copy. Warmy says it cannot.

How Warmy email warmup works

According to Warmy, network mailboxes open every warmup email, reply to up to about 30% of them to form threads, mark messages as Important, and move any that land in spam back to the inbox. Daily volume then rises gradually.

Links are clicked only in seed list mode or with the paid "Warm-up with clicks" add-on. Warmy says it accesses only warmup emails and that you can pause or disconnect a mailbox at any time.

If warmup is new to you, our email warmup guide explains what it does, how long it takes and what no warmup tool can fix.

The warmup network

Warmy's help center describes the network as "mainly Warmy-managed mailboxes, plus a smaller share of accounts belonging to Warmy users." Its FAQ says every connected user joins the network, and a comparison page says Warmy runs separate B2B and B2C networks.

The network size is where Warmy's own figures disagree. The pricing, home and comparison pages say "1M+ mailbox network," while the FAQ says the warmup network has "a minimum of 300,000 active mailboxes." We report both and do not treat either as fact.

We found no published detail on network ownership, screening or provider mix.

Warmup content and your own templates

Warmy generates warmup content by industry, language (30+ languages) and B2B or B2C audience, and you can choose topics such as real estate, software or recruiting. Warmy says each mailbox's conversations are written separately with varied wording.

You can also add your own templates, and their share of warmup traffic can reach 100%. The split works like this, per Warmy's help center:

Each template needs approval, usually within one business day, and Warmy recommends at least 5. Template warmup, topics and languages are reserved for higher tiers; Warmy's lemwarm comparison says topics come from Premium and 30+ languages from Business.

Vendors disagree here: MailReach says template, industry and language warmup do not help reputation, and Warmy builds them in. We have no test data to settle it.

Received warmup emails are archived automatically after about 20 minutes. Warmy advises a distinct "Send from" name with an inbox filter on it, and says not to use "Warmy" or "Warm up" in the sender name or filter rules.

Supported mailboxes and senders

Warmy names Gmail, Google Workspace, Outlook, Microsoft 365, Zoho, Yahoo, iCloud, AOL, GMX, Amazon SES, Brevo, SendGrid, Mailgun and any SMTP provider, and its help center has guides for Mailchimp, Mailjet, SparkPost, Adobe Marketo Engage and more. That breadth is a real strength: Warmy warms marketing and transactional sending, not only mailboxes.

On IMAP, Warmy says it is optional but recommends it, especially for B2B mailboxes. Its custom SMTP guide is stricter and says IMAP is required for that connection type, so turn it on if you can.

Volumes, speed and ramp-up

Warmy's "temperature" is the number of emails a mailbox sends per day. You choose Slow (about 4 to 6 weeks), Medium (2 to 4 weeks) or Fast (1 to 2 weeks), and Warmy recommends Slow, saying Fast can harm reputation in some cases. Volume rises daily toward your plan maximum (100 to 5,000 a day) or a limit you set.

The Adeline AI assistant suggests a starting volume and ramp from mailbox age and history. Warmy says automatic adjustments are "coming soon"; today Adeline recommends and you apply.

How long Warmy says to warm up

Warmy's timelines differ by page, so here is each source as written.

Every version agrees: keep warmup on after you launch. Warmy also suggests starting real sending at 10 to 20 emails a day, verifying every address first, and pausing if bounces or complaints spike; its warm-up calculator says "Bounce rates above 2% signal weak engagement." If your list is the problem, our email bounce rate guide covers hard and soft bounces and the thresholds each sequencer uses. For the domains, mailboxes and DNS behind these limits, see our guide to cold email infrastructure.

The Health Score and other Warmy scores

Each mailbox gets a Health Score from 0 to 100. Warmy's help center publishes the weighting, which is more than most vendors share.

No pass or fail bands are defined. Each test also gives an ISP score from 0 to 10, where Warmy calls 8 to 10 generally good and 4 or below a sign of significant issues.

The largest component, 40%, comes from warmup emails landing in network inboxes. That reads mailbox health, not where your real campaign lands with real prospects, so test actual campaign copy before you trust a launch.

Google Postmaster Tools changes

Google says the old Postmaster Tools interface is being replaced by v2, and that "all old dashboards are available in v2 except the Domain and IP Reputation dashboards, which will be retired." Google's page says the deprecation was postponed and gives no dates.

Warmy's Health Score article still lists domain and IP reputation inside its 25% Postmaster component, while a September 2026 Warmy blog post says those metrics were removed and that its integration helps "bridge the gap." How the score now handles that component is not documented on the pages we read, so ask Warmy if the score drives your decisions.

Warmy seed list and placement tests

Warmy has three related products here, and they do different jobs. Two measure placement; the seed list mainly creates engagement.

The in-app deliverability test

From a mailbox dashboard, you pick B2C providers (Gmail, Outlook, Yahoo, Zoho) or B2B ones (Google Workspace, Microsoft 365, SMTP) and run a test. Warmy says the test sends to mailboxes outside the warmup network.

The report shows Inbox, Spam, Unreceived and Promotions per provider (Warmy counts Promotions as inbox), plus a sending IP blacklist report. Auto-Test is on by default for new accounts, and a test uses credits, 15 in Warmy's example.

Placement tests on real campaigns

You can also mix tracking addresses into a live campaign for 1 to 7 days, with up to 50 emails per provider. Warmy says this is not available for Yahoo or custom SMTP. Our guide to the inbox placement test explains how to read any seed test by provider.

The Seed List product

Warmy's seed list is different from most seed tests. Warmy says its seeds open and scroll your emails, click links at varying intervals, move messages from spam to inbox, mark them Important and randomize timing. It is an engagement product for real campaigns, not only a measurement panel.

You download a CSV, add it to your sending platform (Warmy's examples are Mailchimp and SendGrid), and send to it once per day, in batches if it is over 1,000. If this fits your sending, you can see Warmy's seed list options after signing in.

Warmy's seed list figures conflict too. The product page says "over 500,000 email seeds," one help article describes "a CSV of 60,000+ real seed addresses," and another says sizes run "from 500 to 5,000 seeds" by plan. The fair reading is that the list you receive is sized by plan; seed list prices are not published.

Seed engagement, like warmup engagement, comes from addresses that are not your recipients, so it does not change complaint rates from real people.

Warmy's free tools

Warmy offers a long list of free tools, several without sign-up, which is a good way to judge Warmy before the trial.

Warmy's homepage lists more, including a domain reputation checker, email verifier, SpamAssassin checker, bounce analyzer, header analyzer, BIMI generator and mailbox calculator.

The free deliverability test

You pick how you send (mailbox, marketing system or API), send your usual email to the test addresses, and open the report, which Warmy says usually arrives within minutes. It flags when "less than 80% of test emails reach the inbox." Warmy does not state a usage limit. For a full pre-send routine that combines this with authentication, blacklist and content checks, see our guide to the email deliverability test, and run your copy through our free spam word checker.

The blacklist checker and DNS generators

The blacklist checker's 25 lists include Spamhaus, Barracuda, SpamCop, SORBS, UCEPROTECT and URIBL, and it advises fixing the root cause before requesting removal. The DMARC generator says to start at p=none for about 2 to 4 weeks, then move to quarantine and reject. The DKIM generator recommends 2048-bit keys and keeps the private key on your device.

If you are trying to work out why mail is already landing in spam, our checklist on why your emails are going to spam walks through each cause in order. For a wider view of testers, monitors and checkers beyond Warmy, see our roundup of email deliverability tools.

Other Warmy features

Email Verification. Warmy checks syntax, MX, mailbox existence, catch-all, disposable and role addresses and spam traps, with bulk upload and a real-time API, paid in credits. Warmy claims 99.5% accuracy and under 1% bounce after cleaning, with no published methodology. If verification is your main need, compare the best email verification tools first.

DMARC Monitoring. Warmy turns aggregate (RUA) reports into a per-source dashboard and alerts on a new sending source or a known service failing authentication.

Google Postmaster integration. You share Postmaster access, and Warmy says it uses the data to adjust warmup volume (see Google's dashboard changes above).

Alerts. The Notification Hub sends alerts by email, SMS, Slack or webhook for mailbox issues, domain problems, provider rejections and seed list rotations. Warmy says blacklist alerts are included on every plan.

API. The REST API has an OpenAPI 3.0 spec, what Warmy calls "90+" endpoints, and a published limit of 60 requests a minute. The page also says "To get access to the API, please schedule a short call with us," so plan for that step.

AI Connect (MCP). Claude, ChatGPT, Gemini or any MCP client can read placement, warmup stats, DMARC status and health scores. Whether it can change settings is not stated.

Reputation Repair. A done-for-you service covering audits, DNS fixes, delisting requests and warmup. No price or guarantee is published.

Warmy pricing explained

As of November 12, 2026, Warmy's live pricing page shows three cards (B2B sender, B2C sender and Custom plan), each saying "Plans starting from $49/ month." It shows no plan names, no other prices, no annual option and no daily volumes. On placement tests it says: "Confirm your monthly allowance with the Warmy team."

The five plans (from Warmy's comparison pages)

The plan table below comes from Warmy's own comparison pages (vs MailReach and vs lemwarm, updated November 2026; vs Instantly, updated October 2026), not from the pricing page, which showed none of these figures when we read it.

Warmy's help center confirms the five plan names. The comparison pages say every plan includes placement tests, Postmaster integration, API access, an agency dashboard, DMARC monitoring and email verification, with custom plans above Platinum.

Third-party listings show the same prices with different test allowances: Capterra and a MailReach blog post (MailReach is a competitor and also our affiliate) list as few as 1 test on Starter. Warmy's free test page says every plan includes "at least five placement tests per month," so we use Warmy's figures and suggest you confirm the allowance in Warmy's "See Plans" screen.

Per mailbox or shared volume? Warmy's pages conflict

Warmy prices by daily warmup volume, but its own pages disagree on what one plan covers:

• The Warmy vs MailReach page says "Warmy offers five plans that cover multiple mailboxes," with 100 to 5,000 emails a day per plan "shared across your mailboxes."
• The Warmy vs lemwarm page says "$49 per mailbox, per month" and "Warmy starts at $49 a month per mailbox."
• Help center bulk connection guides say connections are "capped by the mailbox slots in your Warmy plan," while another article says there is no limit to how many inboxes you can sync to an account.

How many mailbox slots each plan includes is not published. Confirm it before you buy, because the two readings produce very different bills.

What each reading costs (our arithmetic)

The tables below are our arithmetic from the comparison-page prices, not Warmy quotes. The first assumes the shared-volume reading and 100 warmup emails a day per mailbox, which is the assumption Warmy's own MailReach comparison uses.

At 50 warmup emails a day per mailbox (our assumption, not Warmy's), Platinum would cover 100 mailboxes at $4.29 each.

The second reading treats $49 as a per-mailbox price.

To put warmup next to domain, mailbox and sequencer costs, our cold email cost calculator adds up the whole stack.

Credits, add-ons and prices on request

One credit balance pays for verification, deliverability tests and the DNS checker. Monthly credits do not roll over, top-up credits do not expire, and neither credits per plan nor top-up prices are published.

Warm-up with clicks, seed list sizes, Reputation Repair and agency or startup discounts are priced on request. There is a coupon field in the app, but we have no Warmy coupon code and do not know of a public one.

Free trial

Warmy offers a 7-day free trial with no credit card. The terms limit it to "seven (7) days, one (1) mailbox, and one (1) user," and it converts to a paid plan unless you cancel before it ends. The trial includes warmup at 15 to 50 emails a day, the deliverability test and template warmup. Warmy's trial guide mentions inviting team members, which sits awkwardly with the one-user limit, so check team access with Warmy.

Billing, refunds and cancellation

Warmy's terms say "YOUR SUBSCRIPTION WILL AUTOMATICALLY RENEW," that monthly fees are billed on or about the 1st of each month for the prior period (post-paid), and that annual fees are billed in advance. Annual terms exist, but no annual price or discount is published.

Warmy's terms say fees are non-refundable and that you must cancel at least five business days before renewal; its help center says refund requests go through support. The help center's refund article says requests "can only be submitted 7 days after the date of purchase," which does not make clear whether that means within 7 days or only after 7 days.

Cancellation is handled by contacting support by chat, WhatsApp or email, and takes effect at the end of the current billing cycle. We did not find a documented self-serve cancel button.

Warmy and Google: where warmup stands

Here is what the published sources say, as of November 12, 2026.

Google's email sender guidelines recommend increasing volume slowly to engaged recipients, sending at a consistent rate and avoiding sudden spikes. They do not mention warmup tools. Gmail's program policies prohibit automating Gmail in ways that mislead or deceive users.

In 2023, GMass said Google required it to shut down its API-based warmup, and it closed that feature on January 31, 2023. Growbots stopped warmup for Google accounts later that year. Both are third-party accounts, and we found no public statement from Google about those events.

What Warmy says

Warmy says it is not affected by those API restrictions and that its warmup emails stay inside its own network. Its GMass comparison post says Warmy "operates independently of the Gmail API restrictions that forced GMass to shut down warmup" because it connects over IMAP.

Warmy's own help center adds a complication. It says OAuth connections for Google Workspace and Microsoft 365 use "the Gmail API or Microsoft Graph API," and Workspace bulk connections use admin app approval or domain-wide delegation with a Warmy service account. Only the app password route is IMAP and SMTP only. We describe the documented setup and make no claim about how Google views any of it.

Warmy's terms make customers responsible for following their email provider's policies, for their own sending practices, and for not using the service for spam. Google has not published a position on warmup networks specifically, so treat automated warmup as a practice Google neither endorses nor explicitly names.

What this means for you

• Under Warmy's terms, the compliance risk sits with the account owner.
• Warmup and seed engagement come from network or seed inboxes, not real prospects. Google's spam-rate thresholds (keep it below 0.10%, and avoid ever reaching 0.30%) apply to complaints from real recipients, which warmup does not change.
• Keep cold volume modest, keep complaints low, and do not treat a warmup score as a license to send more.

Results claims: what Warmy says

Warmy's homepage cites "2.3x higher open rates," "3x higher click rates" and a "35% reduction in bounce rates," and other pages claim 98% average inbox placement. No methodology is given, and we found no independent audit. Warmy itself says Adeline "does not guarantee inbox placement," and the customer logos on its site are not endorsements of any result. Your outcome depends on your list, copy, volume and domain history far more than on any warmup tool.

Warmy for agencies

Warmy's agency page lists all clients, mailboxes and subscriptions in one place, with customizable access levels, shared dashboards and a central admin console. Workspaces are the practical piece: team members are free, each workspace has its own subscription and billing, and you can own up to 100 workspaces.

Growth Hub adds a referral program and "special pricing tailored to your needs" for agencies that bring clients. No agency prices are published, and white label is not mentioned.

The terms clause agencies should read

Warmy's terms say users may not "rent, lease, sell, sublicense, resell, or otherwise commercially exploit the Services," while the agency page and Growth Hub describe managing client mailboxes and bringing clients onto Warmy. We are not interpreting the contract, but if you plan to bill clients for Warmy, ask Warmy in writing how the clause applies. For how warmup fits a multi-client setup, see our guides to agency cold email sending infrastructure and mailbox warmup and inbox placement. Agencies can request a Warmy agency quote from inside the product.

Warmy integrations

Warmy's integrations page shows "229 of 229 connections" while its footer says "36+ providers," so the fair summary is that Warmy lists more than 200 integrations. They include sequencers (Instantly, Smartlead, lemlist, Apollo.io, Clay), CRMs (Salesforce, HubSpot, Pipedrive), Zapier and Make, and about 90 ESPs from Klaviyo to SendGrid. How each sequencer integration works in detail is not documented.

How Warmy fits with Instantly, Smartlead, PlusVibe and lemlist

This is the main buying question for cold email teams, because the popular sequencers already include warmup.

When Warmy adds little. Instantly includes unlimited email accounts and unlimited warmup on its Outreach plans, starting at $47 a month for Growth. Smartlead includes unlimited email accounts from $39 a month on Base, and PlusVibe starts at $37 a month on Personal with Basic warmup. If you run B2B cold email through one of these, a second warmup subscription is hard to justify on cost alone.

When Warmy adds something. Placement testing is an add-on in those tools: Smartlead's SmartDelivery starts at $49 a month, and PlusVibe's Email Placement Test starts at $19 a month for 300 credits. Warmy bundles placement tests, DMARC monitoring and verification with warmup, so a team that wants all of those from one independent vendor may find the bundle simpler.

When Warmy is the main option. If you send from Mailchimp, Klaviyo, SendGrid, Amazon SES, a CRM or a plain mailbox, your platform likely has no warmup built in. That is where Warmy's B2C and ESP warmup fits best.

lemlist users already have lemwarm, which is included with every lemlist plan. Our reviews of Instantly, Smartlead, PlusVibe and lemlist cover each sequencer's built-in warmup.

Warmy vs MailReach and other alternatives

Prices below are from each vendor's own site on monthly billing unless noted. Warmy's figures come from its comparison pages (November 2026), and the other vendors' prices were checked November 10, 2026.

This is list-price arithmetic only. Daily volumes, network quality and included testing differ by vendor.

Warmy vs MailReach

MailReach is the closest comparison, and we are an affiliate of both, so here is the plain math. MailReach costs $25 a mailbox for 1 to 5 mailboxes, $19.50 for 6 to 20 and $18 for 21 to 50, per its own blog. Against Warmy's comparison-page plans on the shared reading, that is $25 vs $49 for one mailbox, $195 vs $189 for 10, $390 vs $279 for 20 and $900 vs $429 for 50 (our arithmetic).

Warmy's own MailReach comparison says MailReach is cheaper for 1 to 5 mailboxes, about even near 10, and Warmy fits better from about 20 mailboxes or for B2C. MailReach focuses on B2B and skips template warmup, while Warmy offers a free trial that MailReach does not advertise for its warmer. MailReach's comparison page says Warmy needs a demo call to start, which does not match Warmy's current self-serve trial. Our side-by-side Warmy vs MailReach comparison goes through it by use case, and our MailReach review covers MailReach on its own terms.

Standalone warmup tools

lemwarm costs $29 per address on Essential and sells template warmup on its higher plan, like Warmy. Warmup Inbox is the low-cost per-inbox option at $15 a month for 75 warmup emails a day. Mailivery has a flat $29 Starter plan with a shared pool of 200 warmup emails a day, and Folderly shows $96 per mailbox a month on yearly billing.

Our full list of Warmy alternatives covers more tools by use case, and our ranking of the best email warmup tools covers the category.

Warmy ratings on review sites

We fetched these on November 12, 2026; treat them as a snapshot.

Warmy's own site displays 4.9 out of 5 for G2, while G2 showed 4.8 when we fetched it, so we use the figure from G2 itself. The Trustpilot score is lower than the G2 and Capterra scores. We did not retrieve review themes, so we do not summarize what reviewers say.

Warmy pros and cons

Pros

• One subscription bundles warmup, placement tests, verification, DMARC monitoring and Postmaster data, per Warmy's comparison pages.
• 7-day free trial with no credit card.
• Warms ESP and transactional sending (Mailchimp, Klaviyo, SendGrid, Amazon SES) as well as mailboxes, with separate B2B and B2C guidance.
• Customizable warmup: topics, 30+ languages, your own templates up to 100% of traffic, provider mix and speed modes.
• A seed list product that engages with real campaigns, useful where SMTP warmup is not possible.
• Many free tools, several with no sign-up.
• Free team members, up to 100 workspaces, and bulk connection of up to 1,000 mailboxes.
• Alerts by email, SMS, Slack and webhook, plus a REST API and an MCP connection.

Cons

• The pricing page shows only "from $49 a month"; the plan table is on comparison pages, and test allowances differ between Warmy and third-party listings.
• Warmy's pages conflict on whether plan volume is per mailbox or shared, and mailbox slots per plan are not published.
• The $49 entry is about double MailReach's single-mailbox price, and sequencers include warmup for unlimited mailboxes.
• Terms say fees are non-refundable, monthly billing is post-paid, and you must cancel through support at least five business days before renewal.
• Warmy's own figures conflict on network size, seed list size, customer counts and integration counts.
• The Health Score leans on warmup placement and on Postmaster reputation data that Google is retiring.
• No white label, and the terms restrict reselling while agency features exist.
• Results claims have no published methodology.

Warmy verdict by use case

How to get started with Warmy

These are the steps Warmy documents. We did not run them ourselves.

1. Run the free deliverability test first. Send a real email to Warmy's test addresses from your normal setup and read the report. No sign-up is needed.
2. Start the trial. Sign up for the 7-day trial with no card. It covers one mailbox.
3. Connect a mailbox. For Gmail, turn on 2-Step Verification, create an app password, and enter it in Warmy with your "Send from" name. For Workspace or Microsoft 365, follow the admin approval steps.
4. Pick Slow speed. Warmup starts automatically once a mailbox is connected, and Warmy advises starting slow.
5. Set a filter and options. Filter warmup mail on your "Send from" name, then choose topics, templates and your provider mix.
6. Launch when ready. Warmy's product page says to launch when placement reaches 85 to 90% or higher, then keep warmup on.

Before the trial ends, confirm your plan, mailbox slots and placement test allowance, and note the cancellation window. When you are ready, create your Warmy account and connect one mailbox before you commit a whole team.

How we compiled this review

We built this review from Warmy's website, comparison pages, free tools, help center and terms as of November 12, 2026, plus Google's own sender guidelines and policies and posts from GMass and Growbots. Competitor prices come from each vendor's own site, and ratings from G2, Capterra and Trustpilot.

We did not use Warmy hands-on. Where Warmy's own materials disagree, we say so instead of choosing a figure.

Rather not build the list yourself?

Warm mailboxes are one piece. Building and verifying the list, writing copy, watching placement and handling replies is a weekly job.

Nerdy Joe is owned by Agency Growth Partners (AGP), and AGP builds verified lists and runs outbound for agencies. If you would rather hand that off, book a call with David. You can also see how the pieces fit in our agency growth machine overview.

Verdict

Warmy covers more of the deliverability stack than most warmup tools, including B2C and ESP sending that most warmers skip.

The weak spots are clarity and terms more than features: the plan table is not on the pricing page, Warmy's pages disagree on per-mailbox versus shared pricing, and fees are non-refundable with a cancellation window to watch.

If you warm more than a handful of mailboxes outside a sequencer, or you send marketing email through an ESP, Warmy is worth a close look. Start with Warmy's free trial, confirm your mailbox slots in writing, and decide from there.
