Where they pull apart

Inframail

Stands out: Unlimited inboxes on your domains for a flat monthly fee, with SPF, DKIM, and DMARC set automatically.

Watch out: Microsoft-backed infrastructure, not Google Workspace. You still need a sequencer such as Instantly or Smartlead to send.

Not the right fit for

Buyers who need Google Workspace inboxes in the $147 plan
Teams that want a free trial before paying

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
