Warmy Pricing: Every Plan, the Per-Mailbox Math and the Fine Print

Warmy pricing starts at $49 a month, and that is the only figure on Warmy's pricing page as of November 2026. Warmy's own comparison pages list five plans from $49 (Starter) to $429 (Platinum) a month, priced by daily warmup volume. The open question is whether one plan covers several mailboxes or the price is per mailbox, because Warmy's pages say both, and the answer can change your bill several times over.

We did not test Warmy hands-on. Every figure below comes from Warmy's pricing page, comparison pages, help center and terms, plus the third-party listings named in each section.

Warmy pricing at a glance

What the Warmy pricing page actually shows

When we read Warmy's pricing page on November 12, 2026, it had three cards: B2B sender ("Reach Businesses"), B2C sender ("Reach Consumers") and Custom plan. Each card said "Plans starting from $49/ month" and nothing more about price.

The page showed no plan names, no daily volumes, no annual option and no "per mailbox" wording. The B2B and B2C cards list the same 14 inclusions, among them the Adeline AI co-pilot, placement test credits, full API access, Google Postmaster data, email verification, DMARC monitoring, a "1M+ mailbox network" and a "500K+ US seed list" (both Warmy's claims), and volume-based pricing.

The Custom plan adds a dedicated success manager with weekly or biweekly guidance. On placement test credits, the page says only: "Confirm your monthly allowance with the Warmy team".

Warmy's five plans (from its comparison pages)

The plan table does not come from the pricing page. It comes from three Warmy comparison pages: Warmy vs MailReach and Warmy vs lemwarm (both marked "Updated November 2026") and Warmy vs Instantly ("Updated October 2026"). All three show the same five plans, and Warmy's help center confirms the plan names.

Billing is listed as monthly only, and custom plans are for volumes above Platinum. Our fetch of the pricing page found none of these numbers, so confirm them in the app (app.warmy.io, under "See Plans") or with Warmy's team.

Per those pages, every plan includes placement tests, Google Postmaster integration, API access, custom warmup settings, the agency dashboard, DMARC monitoring and email verification.

What higher plans add

Warmy's lemwarm comparison says higher plans add warmup volume, credits, warmup topics and language selection, with "warmup topics from Premium" and "30+ languages from Business". Warmy's help center says template warmup, choosing topics and setting the language are reserved for higher tiers, without naming which ones.

If you plan to warm with your own templates or in a language other than English, check which plan includes it before you pick Starter.

Per mailbox or shared volume? Warmy's pages disagree

This is the most important pricing question, and Warmy answers it two ways.

• Shared volume reading. Warmy's MailReach comparison says its five plans "cover multiple mailboxes", that volume is "shared across your mailboxes", and that "several mailboxes can share one plan." Its cost table assumes 100 warmup emails a day per mailbox.
• Per mailbox reading. Warmy's lemwarm comparison says "$49 per mailbox, per month" and "Warmy starts at $49 a month per mailbox."

Other Warmy pages do not settle it. Bulk connection guides mention "the mailbox slots in your Warmy plan", and the FAQ says team members share "the plan's total mailbox count". A help article says there is no limit to the number of inboxes you can sync to an account.

We will not pick one reading as fact. How many mailbox slots each plan includes is not published, so ask Warmy before you buy.

Both readings as our arithmetic

The table below is our math from Warmy's comparison-page prices. The shared column follows Warmy's own assumption of 100 warmup emails a day per mailbox. The per mailbox column applies $49 to every mailbox, as the lemwarm comparison describes.

At 10 mailboxes the gap is $189 against $490 a month. At 50 mailboxes it is $429 against $2,450. That is why the slot question matters more than the plan name.

One more estimate under the shared reading: at 50 warmup emails a day per mailbox (our assumption, not Warmy's), Platinum's 5,000 a day would cover 100 mailboxes at $4.29 each.

Over a year on monthly billing (no annual price is published), the plans come to $588 (Starter), $1,548 (Business), $2,268 (Premium), $3,348 (Expert) and $5,148 (Platinum).

Placement test allowances differ by source

Warmy's free deliverability test page says "Every Warmy plan includes at least five placement tests per month", while a Warmy help article says "at least one available test per month, depending on the plan". Warmy's November 2026 figures (5 to 50) are the newest, but confirm your allowance in the app.

The MailReach blog is a competitor's post (MailReach is also our affiliate), and MailReach says its figures came from G2, Capterra and cached data.

Credits: how tests and verification are paid for

Warmy uses one shared credit balance for Email Validation, the Email Deliverability Test and the DNS Checker. Per its help center:

• Monthly credits come with your subscription, refresh each billing cycle and "don't roll over".
• Top-up credits are bought separately, don't expire, and are used after monthly credits.
• A Deliverability Test needs 15 credits in Warmy's example.
• Auto top-up is off by default.

How many credits each plan includes, and what top-ups cost, are not published.

Add-ons and services priced on request

Discounts and coupons

Warmy's help center mentions multi-mailbox, startup and agency discounts without figures, and says prices "can fluctuate". There is a coupon field under "See plans", but we have no Warmy coupon code and know of no public one.

Warmy free trial: what you get

• Length and card: 7 days from registration, no card required.
• Scope: Warmy's terms limit the trial to "seven (7) days, one (1) mailbox, and one (1) user".
• Volume: the trial guide says "up to 50 of our unique seed emails daily", and elsewhere 15 to 50 emails a day.
• Features: warmup, the slow, medium and fast temperature modes, the deliverability test, template warmup, mailbox stats and Workspaces.
• After the trial: you must upgrade to continue, and the terms say the trial converts to a paid plan unless canceled before it ends.

One conflict to know: the trial guide says Workspaces let you invite team members for free during the trial, while the terms limit the trial to one user. Plan on one mailbox and check team access with Warmy.

Seven days is short: Warmy's product page suggests about 3 to 4 weeks for a new domain and mailbox, so the trial shows the interface, not a finished warmup.

Billing, refunds and cancellation

These points come from Warmy's terms of service (last revised October 1, 2026) and its help center.

Post-paid means your bill around the 1st covers the month you just used. If you plan to stop, contact support at least a week before renewal.

Warmy's free tools cost nothing

Several Warmy tools are free and, per their own pages, need no sign-up:

• Free deliverability test: you send your real email to test addresses and get Inbox, Promotions, Spam and Unreceived results by provider. The usage limit is not stated.
• Blacklist checker: queries 25 lists at once for your domain and its IPs.
• DKIM generator, DMARC generator and warm-up calculator: all free; Warmy calls the calculator "a planning estimate, not a guarantee".

The full tool list is in our full Warmy review. For a step-by-step look at testing in general, see our guide to the email deliverability test.

How Warmy's cost compares

Monthly list prices as of November 2026; arithmetic only, since volumes, networks and testing differ.

MailReach figures come from MailReach's own blog tier table ($25 per mailbox for 1 to 5, $19.50 for 6 to 20, $18 for 21 to 50). Warmy's own comparison claims the same shape under the shared reading: MailReach cheaper for 1 to 5 mailboxes, about even near 10, Warmy cheaper from about 20.

Our Warmy vs MailReach comparison covers the feature side, and MailReach pricing has its full tier math.

Sequencers change the math again. Instantly Growth ($47), Smartlead Base ($39) and PlusVibe Personal ($37) include warmup for unlimited mailboxes in the sending plan, so if you only need basic warmup, see our list of Warmy alternatives. To total warmup with domains, inboxes, data and sending, use the cold email cost calculator.

Which Warmy plan fits which sender

Checklist before you pay

• [ ] Ask Warmy how many mailbox slots your plan includes.
• [ ] Confirm the monthly placement test allowance in the app.
• [ ] Ask for clicks, seed list and top-up prices if you need them.
• [ ] Set a reminder at least five business days before renewal.
• [ ] Run the free deliverability test on your real campaign first.

When you are ready, see Warmy's plans in the app. To plan how many domains and mailboxes you need, see our guide to cold email infrastructure.

A note on Google and warmup

Google's sender guidelines recommend increasing volume slowly to engaged recipients and 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.

Warmy says its warmup emails stay inside its own network, and its terms make customers responsible for following their email provider's policies. Google has not published a position on warmup networks specifically, so treat automated warmup as a practice Google neither endorses nor explicitly names.

Rather not build the list yourself?

Warmup is one line in the outbound budget. The list, the copy and the daily sending take most of the time.

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.

Bottom line on Warmy pricing

Warmy's comparison pages list five plans from $49 to $429 a month as of November 2026, while the pricing page shows only "from $49 a month". If one plan's volume covers several mailboxes, Warmy gets cheap per mailbox at 20 or more; if the $49 is per mailbox, it is one of the pricier warmup tools. Warmy's own pages say both, so get the slot count in writing.

The rest of the fine print is plain: a 7-day, one-mailbox trial with no card, post-paid monthly billing, non-refundable fees, five business days of cancellation notice, and add-ons priced on request. Read the Warmy review for the product side, then check your plan options on Warmy before you commit.
