Mailforge writes DMARC, SPF, DKIM and custom tracking records for every domain you add, following email authentication best practice.
Start sending sequences right away using domains and mailboxes that have already been warmed to build sender reputation.
Apply record changes across many domains at once inside the app instead of editing them one by one at your registrar.
Keep client or project domains organised in separate spaces, and move domains in or out of Mailforge as needed.
An add-on that displays branded websites without revealing your primary domain, with SSL for full transport security.
Mailforge focuses on the unglamorous layer that determines whether cold email works: the sending infrastructure. Instead of asking you to configure SPF, DKIM, DMARC and custom tracking records by hand for every domain you buy, the platform automates that setup and guides you through calculating how many domains and mailboxes you need for a given contact volume. The aim is to get a team from zero to sending in roughly five to ten minutes rather than a day of DNS tinkering.
Deliverability is the core selling point. Mailforge builds what it calls a distributed email infrastructure, spreads mailboxes across many domains and IPs, and ships pre-warmed domains and mailboxes so sequences can start immediately. It also offers bulk DNS updates, multiple workspaces for organising projects, domain transferring in and out, and SSL and domain masking so branded landing pages can be shown without exposing your primary domain.
The product is deliberately sending-software agnostic: you can plug Mailforge into Salesforge or any other outreach tool. It sits inside a broader family of products — Salesforge for multichannel sequences including email and LinkedIn, Leadsforge for lead search, Primeforge for Google and Microsoft 365 infrastructure, and Warmforge for inbox warm-up — which is useful if you want a single vendor, and optionally replaceable if you prefer to mix tools.
Provision enough domains and mailboxes to reach a target contact list without concentrating volume on one domain and damaging inbox placement.
Use separate workspaces per client to keep domains, mailboxes and DNS configurations isolated and auditable.
Get from signup to a working sending setup quickly with automated DNS and pre-warmed mailboxes, then expand volume as reply data comes in.
Consolidate authentication records and monitor deliverability in one place rather than troubleshooting missing DKIM entries mid-campaign.
