Where they pull apart

Hypertide

Stands out: Flat $3.30 per Google inbox, no packages, plus Entra domains at $25 with 25 inboxes included.

Watch out: No free trial. Entra is the volume SKU; Google is per inbox. Month-to-month, cancel in the app.

Not the right fit for

  • Buyers who want a free trial before the first inbox
  • Teams that only want cheap shared SMTP under $1

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
