Where they pull apart

Infraforge

Stands out: Dedicated servers plus a public REST API at api.infraforge.ai for domains, mailboxes, and sequencer export.

Watch out: Minimum 10 slots. Extra IPs are $99 per month billed quarterly. No free trial. Separate from Mailforge.

Not the right fit for

Buyers who need fewer than 10 mailboxes
Teams that expect a high spam-complaint volume

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
