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

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.

  • Teams that want a free trial before paying
