What each one does differently

Zapmail

$39/mo API

Why it comes up: Google and Microsoft mailboxes from $39/mo without a 10-slot Forge minimum.

Stands out: Pre-warmed US/EU Google and Microsoft mailboxes with automated DNS and OAuth export to sequencers.

Best for

  • Freelancers starting with 10 Google inboxes
  • Agencies that want pre-warmed Workspace accounts
  • Teams exporting to Instantly or Smartlead

Mailforge

$3/mailbox/mo

Why it comes up: Cheaper shared-IP sibling from $3 per slot.

Best for

  • Senders who expect some spam complaints

Hypertide

$3.30/inbox/mo API
