Mailforge

Cold email infrastructure set up in minutes

Automated DNS configuration

Mailforge writes DMARC, SPF, DKIM and custom tracking records for every domain you add, following email authentication best practice.

Pre-warmed domains and mailboxes

Start sending sequences right away using domains and mailboxes that have already been warmed to build sender reputation.

Bulk DNS updates

Apply record changes across many domains at once inside the app instead of editing them one by one at your registrar.

Multiple workspaces and domain transfer

Keep client or project domains organised in separate spaces, and move domains in or out of Mailforge as needed.

+Pre-warmed domains and mailboxes let campaigns start immediately
+Works with any sending software rather than locking you into one sequencer
