The short answer
Both sides assessedCheap Inboxes compared with Zapmail
Both sell pre-warmed Google and Microsoft mailboxes. Zapmail bundles ten for $39, adds EU IP options and automated tracking domains, and gates its API to the $299 tier. Cheap Inboxes sells single mailboxes at $3.50 with no bundle, isolates each domain in its own workspace, and includes an API and 24/7 human chat. EU senders should look at Zapmail first; agencies that want per-mailbox flexibility and an API without a top-tier upgrade should look here.
Zapmail compared with Cheap Inboxes
Both sell pre-warmed Google and Microsoft mailboxes. Cheap Inboxes sells single mailboxes at $3.50 with no bundle, isolates each domain in its own workspace, and includes an API and 24/7 human chat. Zapmail bundles ten for $39, adds EU IP options and automated tracking domains, and keeps its API for the $299 tier. European senders and teams that want tracking domains handled should start with Zapmail; agencies that want an API without a top-tier upgrade may prefer Cheap Inboxes.

| Setup time | The FAQ describes automated setup in about ten minutes and the comparison table says same day, while the fulfillment policy says setup typically takes about 48 hours and longer for large orders. Plan on up to two days, then a gradual ramp. | 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. Ordering, domain import, and sequencer export are a few screens, and support will do the migration for you if asked. The judgement that remains is daily caps and how many mailboxes to put on each domain. | 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. |

Strengths and limitations
Cheap Inboxes
Strengths
- Published per-mailbox bands from $3.50 down to $2.80, with no bundle minimum and no setup fee.
- Google and Microsoft at the same price, which makes a mixed pool simple to budget.
- One domain per isolated workspace with full admin access.
- OAuth connections to sequencers with automatic reconnection when a mailbox drops.
Limitations
- No refund if Google suspends an inbox or domain, under the terms of service.
- Setup-time claims are inconsistent, from about ten minutes in the FAQ to a typical 48 hours in the fulfillment policy.
- Pre-warmed is a vendor claim, not a placement guarantee.
- Seven days' notice is requested before cancellation, and pricing on inboxes older than a year can be adjusted.
Zapmail
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.
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.
Pricing compared
Cheap Inboxes
Per mailbox per month on published volume bands, identical for Google and Microsoft, with domains sold separately per year and no setup fee.
- 1 to 99 mailboxes$3.50
- 100 to 249 mailboxes$3.25
- 250 to 999 mailboxes$3.00
- 1,000 mailboxes and above$2.80
At 10,000 cold emails a month and about 30 sends a day per mailbox you need roughly fifteen mailboxes, which is about $52.50 a month plus a few domains at $10 a year, for official Google or Microsoft accounts in isolated workspaces. At 100,000 a month you need on the order of 110 to 150 mailboxes, landing in the $3.25 band at roughly $360 to $490 a month. That is close to Premium Inboxes, whose bands start at the same $3.50 and reach the same $2.80, but Cheap Inboxes reaches its lower rates sooner, at 100 and 1,000 mailboxes rather than 250 and 1,250. Against Zapmail's $39 for ten it is slightly dearer at the bottom and similar in the middle, without a bundle to buy into. The value case is not the name; it is published rates with no package minimum, one domain per workspace, and support that answers quickly. The refund exclusion for Google suspensions is the cost of that price.
Zapmail
Tiered 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.
- Starter$39
- Growth$99
- Pro$299
- Annual billingAbout $2.50
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.
Editorial verdict on each
Cheap Inboxes
Cheap Inboxes is a well-assembled provider-mailbox vendor under an unfortunate name. Official Google and Microsoft accounts at one published price from $3.50 down to $2.80, no bundle to buy into, one domain per isolated workspace with admin access, OAuth connections that reconnect themselves, a real API, and support that answers around the clock is exactly what an agency running dozens of clients needs from this layer. The terms deserve a read before you sign: no refunds for Google suspensions, seven days' notice to cancel, room to reprice inboxes after a year, and setup-time claims that range from ten minutes to two days. The company itself is young and publishes little. For a small team that wants twenty-five real mailboxes without buying thirty, or an agency that values fast human support over a managed service, it belongs on the shortlist next to Premium Inboxes and Zapmail.
Read the full Cheap Inboxes profileZapmail
MomentumZapmail 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.

The best in Cold Email Infrastructure
15 trackedCold email infrastructure providers supply the sending layer underneath an outbound campaign: they register secondary domains, provision Google Workspace, Microsoft 365, or private mailboxes in bulk, write the SPF, DKIM, and DMARC records automatically, and hand the credentials to whichever sequencer you already use.
Official Google, Microsoft, and Azure mailboxes at the lowest published price in the category, with automated DNS, InfraGuard monitoring, and more than twenty sequencer integrations behind them.
Ten minutes of setup, mailboxes live inside two hours with SPF, DKIM, and DMARC already written, and a one-click push into the sequencer, with no sales call at any tier.
Pre-warmed Google and Microsoft mailboxes and a reported one million inboxes across 50,000 businesses by 2026 make Zapmail the category's fastest riser.
Bulk domain and mailbox provisioning with the DNS done automatically collapsed a week of deliverability setup into a checkout flow, and defined how this category now works.
Mailboxes from forty-nine cents with placement testing, IP rotation, an API, and an MCP server included rather than gated, the strongest capability-per-dollar in the category.
