Mailpool
Google, Microsoft, and SMTP inboxes from one dashboard, from $3 an inbox with no minimum
Mailpool is self-serve cold email infrastructure from Estonia that lets a team buy or import domains with an AI domain generator, configures SPF, DKIM, and DMARC automatically, provisions Google Workspace, Microsoft 365, or its own shared-IP SMTP inboxes in bulk, runs a deliverability audit and blacklist monitoring, and exports the inboxes to sequencers over OAuth or CSV, priced per inbox from $3 a month for SMTP, $4 for Google, and $5 for Microsoft, or about 15 percent less on annual billing.
Overview
Mailpool is a provider-agnostic inbox shop. Most vendors in this category commit to one kind of mailbox, either genuine Google and Microsoft seats or private SMTP on their own servers; Mailpool sells all three from the same dashboard and keeps their infrastructures separate. Mailpool Inboxes are SMTP accounts on warmed shared IPs, Google Workspace inboxes go out on Google's US IPs with a custom profile picture, and Microsoft 365 Outlook inboxes use Microsoft's US IPs. A team can mix them to match its prospects' mail providers, and add a dedicated IP server when volume justifies it.
The workflow is built around doing the setup in bulk without a person in the loop. An AI domain generator suggests available variations on your main domain, you buy them in bulk or import domains you already own, and Mailpool writes the SPF, DKIM, and DMARC records, sets up forwarding to your website and a custom tracking domain, and verifies propagation. Inboxes are then created in batches with custom sender names, signatures, and profile pictures, and exported in one click to sequencers over OAuth or as a CSV. A deliverability audit of more than 250 checks, blacklist and spam-rate monitoring, workspaces with roles for clients, and an API round it out. The vendor says setup is fully self-serve with no onboarding fee.
The price list is short but the numbers around it need reading carefully. Month to month, SMTP inboxes are $3, Google Workspace $4, and Microsoft 365 $5 per inbox, and a dedicated IP server is $200; on annual billing those become $2.60, $3.40, $4.30, and $170. The product pages add that volume discounts apply automatically, with 100 or more inboxes bringing SMTP to $2.50, and one page gives a range of $2 to $3.50. Domain prices are not published. Most important for Google buyers, the terms say Mailpool passes on Google's first-year mailbox discount and moves to standard renewal rates after twelve months, so the Google price in year two may be higher than the one on the pricing page. There is no free trial; a first inbox can be bought for $3.
Mailpool is operated by Snowlight Ventures OÜ, a private limited company registered in Tallinn, Estonia, and its privacy policy says data is processed primarily in Estonia. The site does not name founders or publish a founding date. It claims more than 3,000 companies and agencies on some pages and more than 2,000 customers on its about page, along with 250,000 mailboxes created and 45,000 domains managed; those figures are the vendor's own. Its terms were last updated in May 2026, and its blog was adding posts through spring 2026.
Best for
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.
Not the right fit for
- Buyers who want to see the whole bill up front; domain prices and the Google renewal rate after the first year are not published.
- Teams that want a free trial; there is none, though the entry purchase is a single $3 inbox.
- Buyers who need public API documentation before signing up; it is available on request through live chat.
- Anyone shopping for a sequencer or a warmup network; Mailpool provides inboxes and hands them to other tools.
- Organizations that need a named company leadership, security certifications, or an SLA; none are published.
How it works
- 1
You sign up at app.mailpool.ai with no onboarding call; the vendor says the first inbox can be bought for $3 to try the platform.
- 2
You enter your main domain and the AI domain generator suggests available alternatives, which you buy in bulk, or you import domains you already own.
- 3
Mailpool configures SPF, DKIM, and DMARC, domain forwarding to your website, and a tracking domain automatically, then monitors propagation.
- 4
You choose Google Workspace, Microsoft 365, or Mailpool SMTP inboxes and create them in bulk with sender names, signatures, and profile pictures. The vendor says SMTP and Google inboxes are ready in seconds and Microsoft inboxes within a few hours.
- 5
You export the inboxes to your sequencer over OAuth or CSV in one click, then track health with the deliverability audit and blacklist monitoring, manage clients in separate workspaces, or automate the whole process through the API.

Use cases
4 documentedFounder testing cold email
The founder wants a few inboxes on a couple of lookalike domains without committing to a ten-inbox bundle or an annual plan.
Mailpool sells single inboxes month to month, so a handful of Google inboxes at $4 each plus the domains is enough to start, and more can be added later.
Agency matching providers to prospects
One client sells into Microsoft-heavy enterprises while another targets Gmail-using small businesses.
Each client gets its own workspace, with Outlook inboxes for the first and Google or SMTP inboxes for the second, exported to the agency's sequencer from one dashboard.
Outbound team cutting inbox cost
The team runs 100 Google inboxes and wants to move bulk volume to something cheaper while keeping provider inboxes for key segments.
Part of the volume moves to Mailpool SMTP inboxes at about $2.50 to $3, with Google inboxes kept for high-value lists and a dedicated IP added later if needed.
Sales ops lead automating setup
Every new client or product line means buying domains and inboxes by hand.
The API buys domains, creates inboxes in batches, and exports them, so provisioning becomes a script rather than an afternoon of work.
Pricing
from $3 per SMTP inbox per month, $4 per Google Workspace inbox, $5 per Microsoft 365 inbox, billed monthly; $2.60, $3.40, and $4.30 on annual billingPer-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.
| Plan | Price | Includes |
|---|---|---|
| Mailpool (SMTP) | $3 per inbox per month, or $2.60 billed annually |
The inbox creation page says 100 or more inboxes brings the price to $2.50 each, and elsewhere gives a range of $2 to $3.50. |
| Google Workspace | $4 per inbox per month, or $3.40 billed annually |
The terms say this price reflects Google's first-year discount and moves to standard renewal rates after twelve months. |
| Microsoft 365 Outlook | $5 per inbox per month, or $4.30 billed annually |
|
| Dedicated IP | $200 per server per month, or $170 billed annually |
Sold through a contact form rather than self-serve checkout. |
| Dedicated Infrastructure | Custom on demand |

Billing notes
- Annual billing is advertised as saving 15 percent: $2.60, $3.40, and $4.30 per inbox and $170 for a dedicated IP, against $3, $4, $5, and $200 monthly.
- The terms say Google mailboxes carry Google's first-year discount and move to standard renewal rates after twelve months of activity, with the new price shown before renewal; the renewal rate is not published.
- Domain prices are not published on the pricing or domain pages.
- Fees are billed in advance and are non-refundable except where consumer law requires, including where Google or Microsoft treat a service as non-refundable.
- Subscriptions renew automatically; cancellation from the dashboard takes effect at the end of the billing cycle.
- There are no setup or onboarding fees, and invited team members do not need their own subscription.
- The plan feature lists differ between the monthly and annual views, which show 150-plus and 300-plus integrations respectively and add DNS Shield and domain masking only on the annual view.
Value assessment: 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.

Head-to-head comparisons
5 alternativesMailpool vs InboxKit
from About $2.50 per mailbox per month on annual billingBoth sell genuine Google and Microsoft mailboxes with automatic DNS and an API. InboxKit starts at about $2.50 per mailbox on annual billing, adds Azure tenants for cheap Microsoft volume, an MCP server, and a paid monitoring add-on, and exports to more than twenty sequencers. Mailpool charges $3.40 annually or $4 monthly for Google, adds its own SMTP inboxes and a dedicated IP option, and includes a deliverability audit and blacklist monitoring. InboxKit is cheaper for pure Google and Microsoft volume; Mailpool is the better fit for a team that wants SMTP inboxes alongside them.
Full Mailpool vs InboxKit comparisonMailpool vs Zapmail
from $39 per month for ten Google mailboxesZapmail bundles ten Google mailboxes for $39 a month with US and EU IP options and pushes them into more than fifty outreach tools. Mailpool sells single inboxes with no bundle, at $4 for Google month to month, and adds Microsoft 365, SMTP, and dedicated IPs. Zapmail is slightly cheaper per Google inbox at ten and offers EU IPs; Mailpool is better for buying fewer inboxes or mixing mailbox types.
Full Mailpool vs Zapmail comparisonMailpool vs Maildoso
from $75 per month for thirty mailboxes, about $2.50 eachBoth sell SMTP mailboxes with automatic DNS. Maildoso is SMTP only, starts at $75 for thirty mailboxes, about $2.50 each, and falls to about $0.49 at a thousand, with IP rotation and self-healing monitoring. Mailpool's SMTP inboxes start at $3 with no minimum and $2.50 at a hundred, and sit next to Google and Microsoft options in the same account. High-volume SMTP senders should choose Maildoso; teams that want to mix SMTP with provider inboxes should choose Mailpool.
Full Mailpool vs Maildoso comparisonMailpool vs Cheap Inboxes
from $3.50 per mailbox per monthCheap 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.
Full Mailpool vs Cheap Inboxes comparisonMailpool vs Mailforge
from $3 per mailbox slot per month billed yearly, ten-slot minimum, so about $30 per monthMailforge sells mailbox slots at about $3 a month on annual billing with a ten-slot minimum and $14 .com domains, inside the Salesforge stack. Mailpool has no minimum, bills monthly or annually, and lets a team choose Google, Microsoft, or SMTP per inbox. Salesforge users will find Mailforge more integrated; independent teams wanting provider choice and no minimum will prefer Mailpool.

6 categoriesMailpool is a infrastructure tool, and a team running it still has 6 neighbouring categories to staff. The pick in each is MailStrike for email deliverability & warming, ZeroBounce for email verification, Apollo.io for B2B data providers, HubSpot CRM for sales CRM, Expandi for LinkedIn outreach and Zapier for GTM engineering, each the leading tool in that category on published criteria.
- MailStrikeEmail Deliverability & Warming · Innovation
- Because
- Mailpool hands over new mailboxes with no sending history at all. MailStrike warms each on its own behaviour rather than a shared network, and tests placement before launch.
- Benefit
- Campaigns reach the inbox instead of the spam folder, and a reputation problem shows up before the send does.
- ZeroBounceEmail Verification · Category Leader
- Because
- Mailpool is built for infrastructure, not verification. ZeroBounce covers verification on its own.
- Benefit
- Dead addresses come off the list before the send, so the bounce rate never touches the domain.
- Apollo.ioB2B Data Providers · Category Leader
- Because
- Mailpool is built for infrastructure, not data. Apollo.io adds data + engagement in one product.
- Benefit
- Lists get built in minutes from filters, rather than bought, scraped, or typed out by hand.
- HubSpot CRMSales CRM · Category Leader
- Because
- Mailpool lists no founders, founding date, security certifications, or SLA published among its limits. HubSpot CRM adds free unlimited view-only seats.
- Benefit
- Every conversation ends up on a record, so a rep leaving does not take the pipeline with them.
- ExpandiLinkedIn Outreach · Category Leader
- Because
- Mailpool is built for infrastructure, not LinkedIn. Expandi adds agency operations layer.
- Benefit
- A second channel reaches the people who never open email, without a rep doing it by hand.
- ZapierGTM Engineering · Category Leader
- Because
- Mailpool lists domain prices are not published among its limits. Zapier adds free tier plus 14-day trial.
- Benefit
- The workflow nobody wanted to buy a whole tool for gets built in an afternoon.
Pairings follow the methodology: the leading tool in each complementary category, chosen on published criteria. Placement cannot be purchased.
Full Mailpool stackImplementation & onboarding
- Setup time
- The vendor says SMTP and Google inboxes can be created in seconds and a batch of SMTP accounts across domains in under five minutes, while Microsoft 365 inboxes are ready within a few hours. DNS propagation and warmup still need time before full volume.
- Learning curve
- Low. Buying domains, creating inboxes, and exporting them are guided steps in the dashboard; choosing the right mix of mailbox types is the main decision.
- Onboarding
- Fully self-serve with no onboarding fee, live chat support, a help center, and an optional 15-minute call booked through Cal.com.
- Migration notes
- Existing domains can be imported. Inboxes connect to sequencers over OAuth or standard credentials, so changing sequencer is a re-export. Leaving means moving domains and DNS elsewhere; Google and Microsoft accounts are tied to Mailpool's provisioning, so plan the cutover before cancelling.
Platform, API & security
- Platforms
- Web appAPIOAuth and CSV export to sequencers
- API
- An API for domain purchase and setup, batch inbox creation across providers, DNS edits, status monitoring, and export, authenticated with API keys from the dashboard and rate-limited by plan. Documentation is supplied on request through live chat.
- Compliance
- SPF, DKIM, and DMARC configured automaticallyOperated by Snowlight Ventures OÜ under Estonian law; terms reference the GDPR, ePrivacy Directive, and CAN-SPAM as customer obligationsNo compliance certifications publishedThe pricing comparison lists end-to-end encryption, automated backup, and SSO and SAML without specifying which plans include them
- Data residency
- The privacy policy says data is processed primarily in Estonia and in countries where Mailpool's service providers operate.
- SSO
- SSO and SAML appear in the pricing comparison table; plan availability is not stated.
- Security notes
- Google and Microsoft inboxes remain subject to those providers' policies, and the terms state that suspensions imposed by them are outside Mailpool's responsibility. Mailpool may suspend accounts immediately for phishing, spam, or other serious misuse.

Frequently asked questions
12 questionsWhat is Mailpool?
Mailpool is cold email infrastructure. It helps you buy or import domains, sets up SPF, DKIM, and DMARC automatically, creates Google Workspace, Microsoft 365, or its own SMTP inboxes in bulk, and exports them to your sequencer. It does not send campaigns itself.
How much does Mailpool cost?
Month to month, SMTP inboxes are $3, Google Workspace $4, and Microsoft 365 $5 per inbox, and a dedicated IP server is $200. On annual billing those are $2.60, $3.40, $4.30, and $170. Volume discounts apply automatically, and domains are extra.
Is there a minimum order?
No. The vendor says you can start with a single inbox for $3, which it suggests as the way to evaluate the platform in place of a free trial.
Does the Google price stay the same after the first year?
Not necessarily. Mailpool's terms say it passes on Google's first-year mailbox discount and moves to standard renewal rates after twelve months, with the new price shown before renewal. The renewal rate itself is not published.
What is the difference between Mailpool inboxes and Google inboxes?
Mailpool inboxes are SMTP accounts on Mailpool's own warmed, rotating shared IPs and are the cheapest option. Google Workspace and Microsoft 365 inboxes are genuine provider accounts on those companies' US IPs, which cost more and are subject to Google's and Microsoft's policies.
Does Mailpool offer a free trial?
No. There is no free trial, and fees are non-refundable except where consumer law requires, so a single $3 inbox is the practical test.
Does Mailpool have an API?
Yes. The API covers domain purchase, batch inbox creation, DNS changes, monitoring, and export, using keys generated in the dashboard. Documentation is provided on request through live chat.
Can agencies manage several clients?
Yes. Each client can have its own workspace with its own team and billing, and members can be Owners, Admins, or Members with custom access. There is no hard limit on members, and they do not need their own subscriptions.
Who runs Mailpool?
Mailpool is a trade name of Snowlight Ventures OÜ, a private limited company registered in Tallinn, Estonia. The site does not name its founders or publish a founding date.
What should I pair Mailpool with?
Mailpool is a infrastructure tool, and a team running it still has 6 neighbouring categories to staff. The pick in each is MailStrike for email deliverability & warming, ZeroBounce for email verification, Apollo.io for B2B data providers, HubSpot CRM for sales CRM, Expandi for LinkedIn outreach and Zapier for GTM engineering, each the leading tool in that category on published criteria.
What do I pair with Mailpool for Email Deliverability & Warming?
MailStrike. Mailpool hands over new mailboxes with no sending history at all. MailStrike warms each on its own behaviour rather than a shared network, and tests placement before launch.
Is Mailpool enough on its own?
For infrastructure, yes. Mailpool does not cover email verification, B2B data providers and sales CRM, and its own profile says so; ZeroBounce, Apollo.io and HubSpot CRM are the tools that fill those gaps.
Editorial verdict
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.
