Where they pull apart

Mailflow

Stands out: The product is the mailbox and domain layer (infra plus deliverability), not a copy editor and not a LinkedIn sequencer.

Watch out: You still attach a sequencer such as Instantly or Smartlead on top. Mailflow is the pipes, not the cadence UI.

Not the right fit for

  • Users who only need a Gmail merge add-on
  • Teams shopping for LinkedIn automation

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

Pros and cons

Mailflow

  • Infra-plus-deliverability at a $49/mo listing floor
  • Aimed at outbound volume, not internal Gmail
  • Cheaper entry than EmailBison's $599/mo listing
  • Not a LinkedIn or multichannel sequencer
  • Mailbox counts at $49 need a live check
  • Overlap with Instantly plans that already include warmup

Mailforge

  • $3/mailbox/mo on yearly billing
  • Automated DNS on every domain
  • Cancel anytime, no contract
  • 10 mailbox slot minimum
  • No free trial
  • Empty slots still bill
