The same emails a day on both sides
Mailpool is priced on its monthly inbox prices at the volume its help center recommends for each type: SMTP 30 a day, Google Workspace up to 40, Microsoft 365 up to 25, with Instantly for sending and warmup. Mailpool publishes no domain price, so its domains are left out and its totals are a floor. Outreach2day is priced at 25 a day per mailbox with .com domains at $13 a year, 5 mailboxes each.
2,500 a day: 84 Mailpool SMTP inboxes ($252) or 63 Google inboxes ($252), + Instantly Hypergrowth ($97) = from $349; 100 Microsoft inboxes ($500) = from $597. 100 Outreach2day mailboxes $150 + 20 domains $21.67 = $171.67, or $268.67 with Instantly. 5,000 a day: from $685 on SMTP against $343.33. 25,000 a day: from $3,208 on SMTP against $716.67, with our mailboxes at $0.50 from 1,000.
Mailpool's dedicated IP is another route: $200 a server a month with unlimited inboxes and up to 100,000 emails a month per IP, and its help center says you are charged for the volume sent. At 2,500 a day that is one IP and Instantly, from $297 before the volume charge and domains; at 25,000 a day, 6 IPs and Instantly, from $1,906.
Every Mailpool plan and add-on is in Mailpool pricing.
Where they differ
What each one includes
Mailpool: SMTP inboxes on shared rotating IPs, Google Workspace and Microsoft 365 inboxes, automatic DNS, a domain generator, inbox health checks and blacklist monitoring, and export to Instantly, Smartlead, ReachInbox, EmailBison and more. Warmup is sold as warmup slots in billing settings; the API is a premium product shared after an onboarding call; we found no MCP server.
Outreach2day: mailboxes on our own infrastructure, on your domains with DNS set automatically, warmup that starts at once and keeps running, a sequencer with steps, schedules, stop on reply, stats and a reply inbox, a REST API and a hosted MCP server on every account. Our mailboxes land in the inbox. Most people think only Google gets to the inbox and overpay for it. Mailboxes also sync to Instantly and Smartlead by API key.
Terms and the company
Mailpool: run by Snowlight Ventures OÜ in Tallinn, Estonia, with Paddle as the merchant of record. No free trial; you can start with one inbox for $3. Fees are billed in advance and non-refundable apart from the EU 14-day withdrawal right, and the terms call the Google price a first-year discount that moves to an unpublished renewal rate after 12 months. Annual billing takes 13 to 15% off.
Outreach2day: no free trial; month to month on the price you see, cancel any time, 12-mailbox minimum ($30 a month). Details: Mailpool review, Mailpool alternatives, Mailpool pricing.

Why Outreach2day
We make Outreach2day, so this page is ours. Every Mailpool fact above links Mailpool's own page.
Mailpool's inbox price is the mailbox line: warmup slots and the sequencer come on top, and two of its prices, warmup slots and the Google renewal rate, are not published. Outreach2day prices the whole job per mailbox: 25 cold emails a day from day 14, warmup and our sequencer included. Teams that keep Instantly or Smartlead can use our mailboxes there, with warmup running on our side.
Outreach2day mailboxes are $2.50 a mailbox up to 99, $1.50 from 100, $0.50 from 1,000, with warmup, the sequencer and the replies inbox included at every tier. For larger volumes and better prices there is the Enterprise plan: book a call and we size it with you.

FAQ
Mailpool vs Outreach2day: questions
Is Outreach2day cheaper than Mailpool?
At the same emails a day, yes: $171.67 a month against from $349 at 2,500 cold emails a day, $343.33 against from $685 at 5,000 and $716.67 against from $3,208 at 25,000. The Mailpool figures are SMTP inboxes at $3 with Instantly, before domains and warmup slots.
Do both include warmup?
Outreach2day includes warmup for every mailbox for as long as you keep it. Mailpool sells warmup slots in billing settings at a price it does not publish and recommends three to four weeks of warmup before campaigns; in the worked cost above Instantly's plan does the warmup.
Does Mailpool have a discount code?
Mailpool's pricing page lists no code on 2026-11-04. Annual billing takes 13 to 15% off, and it mentions volume discounts for agencies without amounts.
Can I move from Mailpool to Outreach2day?
Yes. Order Outreach2day mailboxes 14 days before you cancel Mailpool so warmup finishes while the old inboxes still send; Mailpool deactivates inboxes at the end of the billing cycle and transfers domains you created there on request. Point your domains at Outreach2day; SPF, DKIM and DMARC are set for you.
