Why teams pick Outreach2day over Maildoso

  • 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

  • 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

  • 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: $1,000 against $1,851.50 at 400 mailboxes.

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 25 of our mailboxes that is $62.50 against $202; at 100, $250 against $514.50; at 400, $1,000 against $1,851.50.

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.

  3. Send from our own sequencer, or sync the mailboxes to Instantly, Smartlead or EmailBison as you do today
  4. Keep the Maildoso mailboxes sending until ours reach full volume on day 21, then cancel
  5. Ask Maildoso to transfer your domains back; its pricing page says the transfer is free when the subscription ends
