The short answer
Both sides assessedCheap Inboxes compared with Mailpool
Mailpool is a broader alternative, adding its own SMTP inboxes, a dedicated IP option, and a deliverability audit to Google and Microsoft mailboxes at $4 monthly or $3.40 annually. Cheap Inboxes keeps the advantage on pre-warmed Google mailboxes, per-domain workspaces, and published domain prices from $2.50 a year.
Mailpool compared with Cheap Inboxes
Cheap Inboxes sells pre-warmed Google and Microsoft mailboxes on Business Starter accounts, each domain in its own workspace, from $3.50 down to $2.80 at a thousand, with domains from $2.50 a year. Mailpool charges $4 monthly or $3.40 annually for Google, does not advertise pre-warming, but adds SMTP inboxes, a dedicated IP, and a deliverability audit. Cheap Inboxes is the better buy for Google mailboxes that are ready sooner and have published domain prices; Mailpool is broader.
Choose Cheap Inboxes if
Agencies and outbound teams that want real Google or Microsoft mailboxes at a published per-mailbox rate without a bundle to buy into, isolated one domain per workspace, and support that answers at 2 a.m. when a client's campaign goes dark.
Choose Mailpool if
Small outbound teams and agencies that want to mix Google, Microsoft, and cheaper SMTP inboxes under one account, buy them one at a time with no minimum, and handle domains, DNS, and sequencer export themselves without a sales call.

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.
Mailpool
Strengths
- Google Workspace, Microsoft 365, and SMTP inboxes in one dashboard, with separate infrastructure for each.
- No minimum purchase: a single inbox can be bought for $3, month to month.
- Published per-inbox prices on both monthly and annual billing.
- AI domain generator, bulk domain purchase, and automated SPF, DKIM, DMARC, forwarding, and tracking domain setup.
Limitations
- Domain prices are not published.
- Google inbox pricing reflects a first-year discount and rises to an unpublished renewal rate after twelve months, according to the terms.
- No free trial and no refunds outside what consumer law requires.
- API documentation is only available on request.
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.
Mailpool
Per-inbox subscription by mailbox type, billed monthly or annually, with automatic volume discounts, a per-server price for a dedicated IP, and custom pricing for dedicated infrastructure. Domains are purchased separately.

- Google Workspace$4
- Microsoft 365 Outlook$5
- Dedicated IP$200
- Dedicated InfrastructureCustom
Mailpool's appeal is flexibility at a fair price rather than the lowest price. Google inboxes at $4 monthly or $3.40 annually sit in the same band as Cheap Inboxes, Premium Inboxes, and InboxKit, and Microsoft at $5 or $4.30 is in line with the market, while SMTP at $3 is more expensive than SMTP specialists such as Maildoso or Winnr, which fall well below $2 at volume. For 10,000 cold emails a month at around thirty sends a day per inbox, about fifteen Google inboxes cost $60 a month or $51 annually, before domains. What Mailpool gives you for that is a single account where all three mailbox types, a dedicated IP, workspaces, and an API live together, and the ability to buy one inbox at a time. The two gaps in the bill are real: domain prices are not published, and the terms say Google pricing moves to renewal rates after year one, so budget for a higher year-two cost on Google inboxes.
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 profileMailpool
Mailpool is a sensible choice for a small team that does not want to pick one kind of mailbox. Google, Microsoft, and SMTP inboxes live in one dashboard, a single inbox can be bought for $3 with no bundle or minimum, and the domain generator, automatic DNS, deliverability audit, client workspaces, and API cover the rest of the setup without a sales call. Its prices are fair rather than the lowest: SMTP specialists undercut it on SMTP and InboxKit undercuts it on Google at annual rates. The bigger caution is what is missing from the price list. Domain prices are not published, the terms say Google inboxes move to an unpublished renewal rate after the first year, the API documentation is on request, and some pricing details differ between pages. Teams that want flexibility and to start small should try it with a few inboxes; teams buying hundreds of Google seats should compare the year-two cost first.
