Short answer

Why teams pick Outreach2day over Maildoso

  1. Warmup is already running

    Maildoso tells you to run 14+ days of warmup with an outside provider or the Instantly pool; ours starts when the mailbox is created and never stops

  2. A sequencer in the same app

    Maildoso has no sequencer, so you add Instantly, Smartlead or EmailBison; we include campaigns, sequences and one inbox for replies

  3. 25 cold emails a day per mailbox

    Maildoso caps each mailbox at 15 cold emails a day; we recommend up to 25, so the same volume takes fewer mailboxes

Maildoso syncs mailboxes to Instantly, Smartlead and EmailBison. So do ours, with warmup already running: $600 against $1,938.50 at 10,000 cold emails a day.

How we count: every vendor at the same emails a day, each at its own published emails per mailbox a day (ours 25, Premium Inboxes 15, Maildoso 15, Mailforge 30, InboxKit 40), so a cheap mailbox that sends fewer emails needs more mailboxes. A month is 22 sending days, so emails a month = emails a day × 22. List prices on monthly billing, in USD, excluding domains, taxes and discounts. A mailbox-only vendor cannot send campaigns on its own, so its total is the full sending setup: its mailboxes, domains and the sequencer plan that covers the volume. Instantly is the reference sequencer, on its published plans for the emails and new contacts a month (emails ÷ 3); Smartlead where Instantly publishes no plan; Mailforge with Salesforge, because its mailboxes cannot be warmed in Instantly. The mailbox line is listed on its own in every cell.Outreach2day on comparison pages: $2.50 a mailbox up to 99, $1.50 from 100, $0.50 from 1,000.

Outreach2day: 25 cold emails per mailbox a day, 5 mailboxes per domain, .com domains at $13 a year (1,000 mailboxes and 200 domains at 25,000 a day; 40,000 and 8,000 at 1,000,000). Instantly and Smartlead with the accounts they sell, at the published plan for the volume; mailbox vendors at their own emails-per-mailbox limit with their domains and the Instantly (Mailforge: Salesforge) plan for the volume. A month is 22 sending days, so emails a month = emails a day × 22. Where a vendor publishes no price at that size the cell says so and the chart leaves it out. At this size the main table's flat $2.50 a Maildoso mailbox gives way to its published packs.

The details

What the full setup costs

Maildoso charges $2.50 per mailbox on its 30-mailbox plan ($75 a month). Warmup and sending are not included. Each mailbox sends up to 15 cold emails a day.

To compare the same email volume we count the Maildoso mailboxes needed at 15 a day, price them at $2.50 each, and add the cheapest Instantly plan, which brings warmup. At 625 cold emails a day that is $62.50 against $202; at 2,500, $150 against $514.50; at 10,000, $600 against $1,938.50.

Other SMTP and Google sellers are compared in Maildoso alternatives.

Domains and refunds

Maildoso domains cost $12 a year ($15 from October 1, 2026) and stay registered with Maildoso while in use. Its pricing page lists a 30-day money-back guarantee; its terms allow a refund only within 30 days, and only if the mailboxes fail to send for 3+ days in a row through Maildoso's fault.

Our domains cost $13 a year for a .com and are registered to you from day one. We have no free trial and no contract: you pay month to month and cancel any time.
