What are cold email services?
Cold email services are agencies that run outbound email for you: they set up separate sending domains and inboxes, build targeted prospect lists, write the sequences, send at volume while protecting deliverability, and hand you the replies. Done well, it is the most controllable way to start conversations with buyers who do not know you yet.
Most agencies rent their sending from two or three layers of middlemen. Koldify is the builder and the vendor: we own the sending infrastructure, so we control the part that fails first and can send the volume it now takes to win.
What’s included in our cold email service
Everything it takes to run cold email at volume, without hiring a team, buying five tools or touching a DNS record. Lists, offer and copy are built together with you.
Sending infrastructure
Dedicated sending domains and inboxes on infrastructure Koldify owns and operates, with SPF, DKIM and DMARC set up for you. Your main domain never sends a cold email.
Warmup and deliverability
Every inbox warms up before it sends. We pace volume, rotate inboxes and watch reputation daily so campaigns keep landing in the primary inbox.
Targeted lead lists
We define your ICP with you, then build lists from firmographic, technographic and buying signals and verify every address before it is used.
Offer and copy
Positioning, first lines, follow-ups and A/B tests, written with you around what your buyers care about. You approve everything before launch.
Sending at volume
Campaigns run at the volume your goals need. Because we own the infrastructure, adding volume means adding inboxes, not adding middlemen.
Replies and reporting
Positive replies are routed to you or your sales team. You get regular reporting on sends, replies and the segments and angles that convert.
Deliverability first, then volume
AI has flooded every inbox, and reply rates are falling across the board. That makes volume necessary to win on ROI, and volume only works if it lands. Keeping thousands of emails a day in the primary inbox is the hard part, so it is the part we own.
- Separate sending domains, so your main domain is never at risk
- SPF, DKIM and DMARC on every domain
- Roughly three weeks of warmup before any campaign sends
- Conservative per-inbox limits and inbox rotation
- Daily reputation monitoring, with volume paced to match
How it works: from kickoff to replies in about a month
New inboxes need time to warm up, so nothing is sent for the first three weeks. We use that time to build your lists and copy, which means launch day is the start of real conversations.
- Week 0
Strategy call and kickoff
We align on your offer, ICP and goals, agree scope and sign a simple month-to-month agreement.
- Week 1
Infrastructure and ICP
Domains and inboxes are set up and authenticated, warmup starts, and we map the accounts and titles to target.
- Week 2
Lists and copy
You review a sample of the prospect list and the first sequences. Nothing goes out without your approval.
- Week 3
Final checks
Inboxes finish warming. We verify the full list, set sending limits and run final deliverability checks.
- Week 4
Launch
Campaigns go live at a measured pace and the first replies start reaching your inbox.
- Week 5 onward
Optimize and scale
We cut what underperforms, double down on the segments and angles that get replies, then add volume.
Cold email agency vs in-house SDR vs DIY tools
Three ways to run outbound. Here is how they compare on the things that decide whether it works.
| Koldify (done for you) | In-house SDR | DIY with tools | |
|---|---|---|---|
| Time to first campaigns | About 4 weeks | 3 to 6 months to hire and ramp | Weeks to months of trial and error |
| Sending infrastructure | Built, owned and monitored for you | You buy and manage it | You buy and manage it |
| Lead data and verification | Included | Separate tools and budget | Separate tools and budget |
| Copywriting and testing | Specialists, tested weekly | Depends on one hire | Up to you |
| Deliverability monitoring | Daily | Rarely a core skill | Up to you |
| Volume ceiling | Scales by adding inboxes | Limited by headcount | Limited by your time |
| Management load | A weekly check-in | Hiring, training, managing | You run everything |
| Commitment | Month-to-month | Salary, benefits, notice periods | Annual tool contracts are common |

Is our cold email service a fit?
Outbound is a multiplier. It works best when the offer is already good and someone is ready to take the conversations.
A great fit if
- You sell B2B, with a clear offer and a deal size that justifies outbound
- You or your team can reply quickly and take the meetings
- You want a steady flow of conversations, not a one-off list
- You would rather not build and babysit sending infrastructure
Probably not a fit if
- You need guaranteed sales without a proven offer
- You sell low-ticket products to consumers
- Nobody on your side has time to follow up on replies
- You want to send from your main company domain

Frequently asked questions
How much do cold email services cost?
Most done-for-you cold email programs are priced as a monthly retainer based on sending volume. We scope your plan on a call around your market and goals. Every plan is month-to-month, with no long-term contract.
How soon will I see results?
New inboxes warm up for about three weeks before any campaign sends, so most campaigns launch around week four. Replies typically start in the first week or two after launch, depending on your offer and market.
What if we don’t get results?
You are never locked in. Plans are month-to-month, and we review results with you every week so we can change targeting, offer or copy quickly when something is not working.
Will cold email hurt my domain or land in spam?
We never send from your main domain. Campaigns go out from separate, authenticated domains and inboxes that are warmed up, rotated and monitored daily, which protects your brand and keeps emails in the primary inbox.
Where do your lead lists come from?
We build lists around your ICP using firmographic, technographic and buying signals from multiple data sources, then verify every address before sending. You review a sample before launch.
Who handles the replies?
Positive replies are routed to you or your sales team, so you can respond, book and close while the conversation is warm. We handle everything up to the reply.
What do you need from me?
A clear offer, input on your ideal customer, approval of lists and copy before launch, and someone to follow up on replies quickly. We handle the rest.
Is cold email legal?
B2B cold email is legal in most markets when you follow the rules: accurate sender details, a clear way to opt out and relevant outreach. CASL in Canada and GDPR in the EU are stricter, and we plan campaigns around them.
Do you work with my industry?
We work with B2B companies across SaaS, IT, agencies, financial services, business funding, healthcare, manufacturing, logistics and professional services. If your buyers have an inbox and a problem you solve, it is worth a call.
