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

Mailforge

Stands out: Automated SPF, DKIM, and DMARC plus mailbox slots you can delete and recreate at no extra cost.

Watch out: Minimum 10 mailbox slots. No free trial. You pay for slots even if some sit empty. Separate from Infraforge and Primeforge.

Not the right fit for

Buyers who need fewer than 10 mailboxes
Teams that want a free trial before buying domains
