Where they pull apart

Mailreef

Stands out: Your own mail server and IP, with unlimited free inboxes and developer API access on every plan.

Watch out: The $240 rate needs a 12-month commitment. Month-to-month Agency Flex is $249/mo. Both add $0.001 per send.

Not the right fit for

  • Solo senders who only need a handful of mailboxes
  • Buyers who refuse a 12-month term and a per-send fee

Mission Inbox

Stands out: REST API, SDKs, SMTP, and webhooks sit beside mailbox plans, so developers can send without a sequencer UI.

Watch out: Lite pauses on overage instead of billing extra. Scale overage is $3 per mailbox and $1 per thousand sends.

Not the right fit for

  • Buyers who need unlimited sends on Lite
  • Teams that only want Google Workspace resale
