Why Outreach2day

Why Outreach2day tops this list

  • Warm-up from day one

    Maildoso leaves warm-up to outside tools. Ours starts on day one and runs for the life of the mailbox.

  • No sequencer bill

    No Instantly or Smartlead plan on top: campaigns, sequences and a reply inbox are in the $2.50.

  • Up to 25 a day per mailbox

    Maildoso caps mailboxes at 15 cold emails a day. We recommend up to 25.

Maildoso costs less from 129 mailboxes up, if you run warm-up and sending in other tools.

How we count: 550 cold emails per mailbox a month (25 a day on 22 working days), the same for every vendor. List prices on monthly billing, in USD, without domains, taxes or discounts. A vendor that does not sell sending gets the cheapest Instantly plan that covers the volume.

The details

What to look for in a Maildoso alternative

Price the full setup, not the mailbox. A $0.49 mailbox still needs warm-up and a sequencer, and the sequencer is often the bigger line.

Check the daily cap. At 15 cold emails a day, Maildoso needs 42 mailboxes for the volume 25 of ours send.

Check who owns the domains. Maildoso registers them with itself while in use; we, Zapmail and Mailforge leave them with you.
