Where they pull apart

EmailBison

Stands out: One $599 price with no seat fees, dedicated IPs, warmup, and a private Slack channel.

Watch out: Buying is a demo, not self-serve checkout. Extra volume is extra monthly buckets above 500,000 emails.

Not the right fit for

  • Solo senders who need a $49 starter
  • Buyers who want to check out without a demo

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
