Zapmail
Pre-warmed Google and Microsoft mailboxes, connected to your sequencer in minutes
Zapmail is cold email mailbox infrastructure, not a sending platform: it automates domain registration, provisions paid Google Workspace and Microsoft 365 mailboxes on US and EU IP addresses, configures SPF, DKIM, DMARC, and custom tracking domains for you, and pushes the mailboxes into more than fifty outreach tools including Instantly, Smartlead, Reply, and lemlist, starting at $39 a month for ten mailboxes.
Overview
Zapmail sells the boring layer that decides whether your campaigns work. It is not a sequencer: there are no email sequences, no unified inbox, no reply management, and no campaign reporting. What it does is register the secondary domains you send from, create paid Google Workspace and Microsoft 365 mailboxes on them, write every DNS record those mailboxes need, and then hand the whole set to whichever outreach tool you already pay for. A small business running outbound will carry two bills, one for the sending platform and one for the infrastructure, and Zapmail is a candidate for the second.
Its distinguishing pitch is pre-warming. Most infrastructure vendors provision a clean mailbox and leave you to warm it for two or three weeks before it is safe to send from, which is dead time you are paying for. Zapmail markets its mailboxes as pre-warmed and ready to use, which if it holds compresses the timeline between purchase and first campaign considerably. Treat it as a scheduling advantage rather than a guarantee: a mailbox with some warming history is still a new sender to any given recipient domain, and ramping gradually remains the correct behavior.
Pricing is straightforward and bundled by mailbox count rather than sold purely per unit. Starter is $39 a month for ten Google mailboxes with additional ones at $3.50 each, Growth is $99 for thirty with extras at $3.25, and Pro is $299 for a hundred with extras at $3.00, adding priority support and API access. Annual billing brings two months free, which the vendor quotes as dropping the effective per-inbox cost to around $2.50. All plans include US or EU IP accounts, which matters for anyone selling into Europe.
The company launched in the early 2020s and reports substantial scale: over a million mailboxes set up, more than 330,000 domains under management, and 50,000 businesses using it, with a Trustpilot rating around 4.5. Public information on its founders and ownership is thin and the third-party profiles that claim to name them are unreliable, so treat the corporate detail as less verified than the product detail. What is well documented is the product itself, which is sold entirely self-serve with published prices and no sales call.
Best for
Agencies, lead-generation teams, and small businesses that have already chosen a sending platform and need ten to a few hundred authenticated mailboxes quickly, with domains, DNS, tracking domains, and forwarding handled for them and a shorter wait before the first campaign.
Not the right fit for
- Anyone shopping for a sending platform; Zapmail has no sequences, no inbox, and no reporting, so buying it alone leaves you with mailboxes and nothing to send from.
- Businesses sending a few hundred emails a month from one mailbox, who should use the Google Workspace account they already have rather than buying a ten-mailbox plan.
- Buyers optimizing purely for unit cost at very high volume, where shared SMTP infrastructure sells mailboxes for well under a dollar each.
- Teams that need dedicated isolated IP space and full control of their own mail servers, which is a private-infrastructure purchase rather than a managed mailbox one.
- Anyone treating pre-warmed as meaning safe to blast on day one; ramping and placement testing still decide whether the investment pays off.
How it works
- 1
You choose how many mailboxes you need, either from the bundled plans or by adding extras at the per-mailbox rate. The plan is the unit of purchase rather than a per-slot subscription with a minimum.
- 2
You buy domains inside Zapmail or connect ones you already own. From that point the tool takes DNS off your hands: nameservers, MX, SPF, DKIM, DMARC, and a custom tracking domain are configured automatically per domain, and email forwarding is handled so replies to a secondary domain reach a mailbox you actually read.
- 3
Mailboxes are provisioned as paid Google Workspace or Microsoft 365 accounts on US or EU IPs. AI helpers generate domain names and mailbox naming conventions in bulk, which sounds trivial until you are naming your ninetieth mailbox by hand.
- 4
You connect the mailboxes to your outreach tool. Zapmail advertises one-click integration with more than fifty platforms including Instantly, Smartlead, Reply, and lemlist, so the credentials never need to be copied by hand into a connection form.
- 5
You then ramp. Zapmail positions its mailboxes as pre-warmed so you can start sooner than with a cold provision, but sensible daily caps and gradual volume increases still apply, and placement-test credits included with the plans let you check where your mail is actually landing before you scale.
Feature breakdown
25 features in 5 modulesMailbox provisioning
Real provider accounts, created in bulk, with the warming argument attached.- Paid Google Workspace mailboxes
- Accounts are genuine paid Workspace mailboxes rather than lookalike infrastructure, which is what receiving servers increasingly check for.
- Microsoft 365 mailboxes
- The Microsoft path exists alongside Google, so you can build a mixed pool and let your sequencer match sending provider to recipient provider.
- Pre-warmed mailboxes
- The headline claim: accounts are positioned as ready to use without the usual weeks of warm-up, which compresses the gap between purchase and first campaign. Sensible ramping still applies.
- US and EU IP addresses
- Every plan includes US or EU IP accounts, which matters for anyone selling into Europe where sending from an unexpected region is a small but real reputation drag.
- Bulk creation with AI naming
- A domain name generator and automated mailbox naming create dozens of accounts at once instead of one form at a time, which is the actual bottleneck at any real scale.
- Five-minute average setup
- The vendor reports an average setup time of about five minutes from purchase to usable mailboxes, against hours or days of manual provisioning.
Domains, DNS, and authentication
Everything you would otherwise be pasting into a registrar panel at midnight.- SPF configured for you
- The Sender Policy Framework record authorizing your sending servers is written automatically per domain, without the syntax errors and lookup-limit breaches that fail silently.
- DKIM keys generated and published
- Signing keys are created and the public key published in DNS on every domain, so receivers can verify the message was not altered in transit.
- DMARC policy published
- A DMARC record is set on each domain, which since the 2024 Gmail and Yahoo bulk sender rules is effectively mandatory rather than a nice extra.
- Custom tracking domains
- Automated setup of a tracking domain per sending domain, so open and click links do not run through shared infrastructure that filters already distrust. Most infrastructure vendors leave this to you.
- Domain registration or bring your own
- Buy secondary domains inside Zapmail or connect existing ones, with DNS record management handled either way.
- Email forwarding
- Replies to a secondary sending domain forward to a mailbox someone actually reads, which is the detail people forget until a warm reply disappears into an address nobody monitors.
Reputation protection across a pool
How the architecture limits damage when a domain goes bad.- Private domain per mailbox group
- The vendor's stated design is that each mailbox is a paid account on its own private domain with a unique sending fingerprint rather than a shared identity in a common pool.
- No shared sending IPs
- Zapmail positions against shared-IP infrastructure, arguing that a mailbox whose reputation is entangled with other customers' behavior is a liability you cannot manage.
- Primary domain isolation
- The whole point of buying secondary domains is that cold outbound never touches the domain your invoices, contracts, and support tickets run on. A blacklisted secondary domain costs a domain fee, not your business email.
- Placement test credits included
- Plans bundle inbox placement test credits, so you can measure where your mail is actually landing across providers instead of inferring it from reply rates.
- AI Insights credits
- Bundled credits for the vendor's analysis tooling, aimed at spotting deliverability problems in a pool before they show up as a collapsed campaign.
Connecting to your sending platform
The integration surface, which is unusually broad for this layer.- More than fifty outreach tool integrations
- One-click connection into Instantly, Smartlead, Reply, lemlist, and dozens of others, so mailboxes arrive in your sequencer without manual credential entry.
- API access on Pro
- The $299 tier adds API access for programmatic provisioning, which is how an agency spins up a client's infrastructure without touching the console.
- Standard IMAP and SMTP credentials
- Because these are ordinary provider mailboxes, they connect to anything that accepts a mailbox, not just the listed integrations.
- AI persona snapshots
- Automated generation of consistent sender identities across a pool, so mailboxes look like people rather than a numbered sequence.
Plans and commercial terms
Bundled by mailbox count, fully self-serve.- Bundled mailbox counts
- Ten mailboxes for $39, thirty for $99, a hundred for $299, rather than a per-slot subscription with a minimum purchase.
- Volume pricing on extras
- Additional mailboxes beyond the bundle cost $3.50, $3.25, or $3.00 depending on tier, so the marginal rate falls as you scale.
- Annual billing with two months free
- Committing annually brings the effective per-inbox cost down toward $2.50, which is competitive with shared infrastructure for real provider accounts.
- Priority support on Pro
- The top tier adds priority support alongside API access, which is the practical reason agencies sit there rather than stacking extras onto Growth.
Use cases
4 documentedAgency onboarding a client under a deadline
The client signed on Monday and expects campaigns live within the week, which a three-week warm-up cycle makes impossible.
Domains, mailboxes, DNS, tracking domains, and forwarding are provisioned in minutes, mailboxes arrive pre-warmed, and one-click integration pushes them straight into the agency's Smartlead workspace.
European B2B team selling into the EU
Sending from US infrastructure into European prospects adds an avoidable reputation penalty and complicates the compliance story.
EU IP accounts are included on every plan, so mail originates from the region it is addressed to, and the secondary domains keep outbound off the company's real domain.
Founder scaling from ten to a hundred mailboxes
The Starter setup worked, volume tripled, and hand-provisioning ninety more mailboxes is an unpleasant week of work.
The Pro plan bundles a hundred mailboxes at $299 with API access, and bulk naming plus automated DNS make the expansion an afternoon rather than a project.
Operator diagnosing a placement problem
Reply rates dropped and nobody can tell whether the copy, the list, or the infrastructure is at fault.
Bundled placement-test credits show exactly which providers are filtering, so the team fixes the real problem instead of rewriting subject lines for a month.
Pricing
from $39 per month for ten Google mailboxesTiered monthly plans bundling a fixed number of mailboxes, with additional mailboxes priced per unit at a rate that falls with tier; domains and IP geography included, annual billing available.
| Plan | Price | Includes |
|---|---|---|
| Starter | $39 per month |
Roughly $3.90 a mailbox, which is the honest entry rate before annual discounting. |
| Growth | $99 per month |
The volume most agencies actually land on, at about $3.30 a mailbox. |
| Pro | $299 per month |
About $3.00 a mailbox, and the only tier with an API, which is the reason agencies sit here. |
| Annual billing | About $2.50 per inbox per month equivalent |
|
Billing notes
- Plans bundle mailboxes rather than charging a flat per-slot rate, so the effective per-mailbox cost falls from about $3.90 on Starter to about $3.00 on Pro before any annual discount.
- Annual billing gives two months free, which the vendor quotes as bringing the effective per-inbox cost to around $2.50, making Zapmail competitive with shared infrastructure while still supplying real provider mailboxes.
- Domain registration and DNS management are handled inside the product; budget separately for the domains themselves as with any infrastructure vendor.
- API access is gated to the $299 Pro tier, which is a meaningful constraint for a small agency that wants programmatic provisioning at thirty mailboxes rather than a hundred.
- There is no published free trial, since every mailbox carries a real Google or Microsoft licence cost.
- Pre-warming is bundled into the mailbox rather than sold as a separate warm-up subscription, which is a genuine cost difference against vendors that charge for warm-up on top.
Value assessment: Model against volume. At 10,000 emails a month, a conservative 30 sends a day per mailbox needs roughly eleven to fifteen mailboxes, so the $39 Starter plan plus a couple of extras covers it for well under $60, which is cheap for real provider accounts with tracking domains and pre-warming included. At 100,000 a month you need on the order of 110 to 150 mailboxes, so Pro at $299 plus extras lands around $330 to $450 a month, or nearer $250 to $340 on annual billing. That is roughly the same territory as Primeforge and Mailforge and a large multiple of what shared SMTP infrastructure costs. The value case rests on two bundled items that competitors charge for separately: pre-warming and automated custom tracking domains. If you would otherwise buy a warm-up subscription, Zapmail is better value than the sticker suggests.
Strengths & limitations
Strengths
- Provisions genuine paid Google Workspace and Microsoft 365 mailboxes rather than lookalike shared infrastructure.
- Pre-warmed mailboxes compress the gap between purchase and first campaign, which is the single most valuable thing an agency under a client deadline can buy.
- Automated custom tracking domain setup per sending domain, which most infrastructure vendors leave you to configure yourself.
- US or EU IP accounts on every plan, which is a real advantage for anyone selling into Europe.
- One-click integration with more than fifty outreach tools including Instantly, Smartlead, Reply, and lemlist, so mailboxes land in your sequencer without manual credential entry.
- Email forwarding on secondary domains is handled, which prevents warm replies vanishing into an unmonitored address.
- Fully self-serve with published prices, no sales call, and reported scale of over a million mailboxes provisioned across 50,000 businesses.
Limitations
- Not a sending platform, so it is always a second bill alongside a sequencer.
- API access is locked to the $299 Pro tier, which is expensive if you want programmatic provisioning at modest scale.
- Pre-warmed is a vendor claim about mailbox history, not a guarantee of placement, and treating it as permission to send at full volume immediately will still burn accounts.
- Per-mailbox cost is several times what shared SMTP infrastructure charges, which matters at very high volume.
- Public information on the company's founders and ownership is thin, and third-party profiles claiming to name them are demonstrably unreliable.
- No free trial, so evaluation means paying for at least a month of real licences.
- Formal compliance certifications and data residency guarantees are not published, which will matter to some buyers.
Head-to-head comparisons
5 alternativesZapmail vs Primeforge
from $4.50 per mailbox slot per month, ten-slot minimum, so about $45 per monthThe most direct comparison: both sell real Google Workspace and Microsoft 365 mailboxes with automated DNS. Zapmail leads on pre-warming, custom tracking domains, EU IP options, and fifty-plus one-click integrations, and bundles ten mailboxes for $39. Primeforge is priced per slot at $4.50, includes an API at every tier, and sits inside a stack that also sells sending and warm-up. Choose Zapmail to shorten the time to first campaign; choose Primeforge for the API at lower volume and the wider product ladder.
Full Zapmail vs Primeforge comparisonZapmail vs Mailforge
from $3 per mailbox slot per month billed yearly, ten-slot minimum, so about $30 per monthMailforge is the cheaper shared-infrastructure option at $3 a slot with a ten-slot minimum and no warming, no tracking-domain automation, and no marketed API. Zapmail costs more per mailbox but supplies real provider accounts, pre-warming, tracking domains, and forwarding. If you already own a warm-up tool and want the lowest provisioning cost, Mailforge wins; if you want fewer moving parts, Zapmail does.
Full Zapmail vs Mailforge comparisonZapmail vs Maildoso
from $75 per month for thirty mailboxes, about $2.50 eachDifferent architectures. Maildoso runs its own SMTP infrastructure with IP rotation and self-healing mailboxes at $0.49 to $2.50 each, but recommends about fifteen cold emails a day per mailbox, so you buy far more of them. Zapmail sells fewer, dearer, real provider mailboxes with higher per-mailbox throughput. Operators chasing unit cost at scale take Maildoso; buyers who want their mail sent from actual Workspace and Microsoft accounts take Zapmail.
Full Zapmail vs Maildoso comparisonZapmail vs Smartlead
from $39/moComplementary rather than competing. Smartlead is the sending platform with unlimited connected mailboxes, which means the constraint on your program moves entirely to how many real mailboxes you are prepared to buy. Zapmail supplies them and pushes them into Smartlead with one click. The pairing is common precisely because neither product overlaps the other.
Full Zapmail vs Smartlead comparisonZapmail vs Instantly
from $37/moInstantly is the sequencer and also sells its own done-for-you accounts, so there is genuine overlap at checkout, and buying everything from one vendor is simpler to administer. Buying Zapmail separately usually gives better per-mailbox economics at volume, adds EU IP options and tracking-domain automation, and keeps your infrastructure portable if you later change sending platform.
Full Zapmail vs Instantly comparisonImplementation & onboarding
- Setup time
- The vendor reports about five minutes from purchase to usable mailboxes, and pre-warming is meant to remove the usual two-to-three-week wait. Plan on days rather than weeks, with gradual ramping and placement testing before full volume.
- Learning curve
- Low for the tool and moderate for the discipline. Provisioning is a few screens. What still requires judgement is daily caps per mailbox, how many mailboxes to put on a domain, and when to retire an account, none of which the tool decides for you.
- Onboarding
- Entirely self-serve with published prices and no sales call at any tier. Priority support arrives at the $299 Pro plan; below that, support is standard.
- Migration notes
- Existing domains can be connected rather than re-registered, preserving any age they have. Because these are ordinary provider mailboxes with standard IMAP and SMTP credentials, moving to a different sequencer means reconnecting the same mailboxes elsewhere rather than rebuilding infrastructure. Leaving Zapmail means repointing DNS and losing the hosted mailboxes, so treat domains as the portable asset.
Platform, API & security
- Platforms
- Web appBulk domain and mailbox provisioning consoleREST API on the Pro tier
- API
- API access is included on the $299 Pro plan for programmatic domain and mailbox provisioning; lower tiers are console-only.
- Compliance
- SPF, DKIM, DMARC, and custom tracking domains configured automatically per domainMailboxes are genuine Google Workspace and Microsoft 365 accounts subject to those providers' acceptable use policiesCAN-SPAM and GDPR sender obligations remain entirely yours, since Zapmail supplies infrastructure and never touches campaign content
- Data residency
- US or EU IP accounts are offered on every plan; formal data residency commitments are not published.
- SSO
- Not advertised.
- Security notes
- The vendor's stated architecture is that every mailbox is a paid provider account on its own private domain with a unique sending fingerprint, explicitly positioned against shared IPs and recycled domains. Authentication and spam handling are therefore Google's and Microsoft's, which helps placement and also means both providers enforce their own policies against abusive bulk sending regardless of who provisioned the account.

Frequently asked questions
10 questionsWhat is Zapmail and is it a sending platform?
Zapmail is mailbox infrastructure, not a sending platform. It registers domains, provisions paid Google Workspace and Microsoft 365 mailboxes, configures SPF, DKIM, DMARC, and custom tracking domains, and pushes the mailboxes into your outreach tool. It has no sequences, no unified inbox, and no campaign reporting, so it is bought alongside something like Instantly or Smartlead rather than instead of it.
How much does Zapmail cost per mailbox?
Starter is $39 a month for ten Google mailboxes with extras at $3.50 each, Growth is $99 for thirty with extras at $3.25, and Pro is $299 for a hundred with extras at $3.00 plus API access and priority support. That works out at roughly $3.90 to $3.00 a mailbox. Annual billing gives two months free, which the vendor quotes as bringing the effective cost to about $2.50 per inbox per month.
Are Zapmail mailboxes really pre-warmed?
The vendor positions them as pre-warmed and ready to use without the usual weeks of warm-up, which is its main differentiator against competitors that provision cold accounts. Treat that as a scheduling advantage rather than a guarantee: a mailbox with warming history is still an unknown sender to any specific recipient domain, so ramp gradually and use the bundled placement-test credits to check where your mail is landing before scaling.
Does Zapmail set up SPF, DKIM, and DMARC for me?
Yes, automatically on every domain, along with nameservers, MX records, a custom tracking domain, and email forwarding. The tracking domain automation is worth calling out because most infrastructure vendors stop at authentication and leave you to configure tracking yourself, which is where open and click links otherwise end up running through shared infrastructure that filters distrust.
How does Zapmail protect domain reputation across a pool?
By isolation rather than magic. The stated design is that each mailbox is a paid provider account on its own private domain with a unique sending fingerprint, explicitly not sharing IPs or recycled domains with other customers. Volume spreads across many cheap secondary domains, so a blacklisted domain costs a domain fee and a few mailboxes instead of the domain your invoices and support run on. Bundled placement tests let you spot a problem before it becomes a collapsed campaign.
Does Zapmail offer EU-based sending?
Yes. Every plan includes US or EU IP accounts, which is a genuine advantage if you sell into Europe, since mail originating from an unexpected region carries a small but real reputation penalty. Formal data residency commitments beyond IP geography are not published, so confirm with the vendor if that is a hard requirement.
Does Zapmail have an API?
Yes, but only on the $299 Pro plan. The API covers programmatic provisioning, which is how an agency spins up an entire client setup without touching the console. If you want an API at thirty mailboxes rather than a hundred, Primeforge includes one in its base subscription and is worth comparing.
Which sending platforms does Zapmail work with?
It advertises one-click integration with more than fifty outreach tools including Instantly, Smartlead, Reply, and lemlist. Because these are ordinary Google Workspace and Microsoft 365 mailboxes with standard IMAP and SMTP credentials, they will also connect to anything else that accepts a mailbox, so you are not locked to the listed integrations.
How many mailboxes do I need for my volume?
Work back from a conservative daily cap. At around 30 cold emails a day per mailbox, 10,000 a month needs roughly eleven to fifteen mailboxes, so Starter plus a few extras. 100,000 a month needs on the order of 110 to 150 mailboxes, which is the Pro plan plus extras at roughly $330 to $450 a month, or nearer $250 to $340 on annual billing.
Who owns Zapmail?
Ownership and founder details are not clearly disclosed on the vendor's own materials, and third-party profiles claiming to name the founders are unreliable enough to disregard. What is documented is scale and product: over a million mailboxes provisioned, more than 330,000 domains managed, roughly 50,000 businesses using it, and a Trustpilot rating around 4.5. Buyers who need a verified corporate counterparty should weigh that thinness accordingly.
Editorial verdict
Zapmail is the infrastructure vendor to look at when time matters. Real Google Workspace and Microsoft 365 mailboxes, automated SPF, DKIM, DMARC, custom tracking domains, forwarding, US or EU IPs, and one-click delivery into fifty-plus sequencers, starting at $39 for ten mailboxes, is a well-assembled bundle, and pre-warming genuinely removes the two-to-three-week dead zone that makes every other infrastructure purchase feel slow. The two bundled items competitors charge extra for, warming and tracking domains, do most of the work in the value case. Be clear that it is not a sending platform and never will be, that pre-warmed is a head start rather than a licence to blast, that the API is stuck behind the $299 tier, and that corporate transparency is thinner than the product quality. For an agency that needs a client live this week, it is the easiest purchase in this layer.
