About Mailforge
What Is Mailforge
Mailforge is a cold email infrastructure platform from the team behind Salesforge. Instead of sending from a personal Gmail account and hoping it lands, you buy domains and mailboxes inside the app and run your outreach through infrastructure built for cold mail. The setup handles DMARC, SPF, DKIM, and custom domain tracking for you, so a non-technical founder can get a working sending stack in about five minutes.
The problem it solves is deliverability. Cold email lives or dies on whether your messages reach the inbox instead of the spam folder, and that depends on domain reputation, authentication records, and how much you send from each mailbox. Mailforge spreads your volume across many domains and mailboxes, pre-warms them, and keeps the technical records current. You focus on the sequence, not the plumbing.
Two things shape where it fits. It's a send layer, not a full sequencer: Mailforge gives you the mailboxes, but you still need a sending tool like Salesforge to write and fire the campaigns. And it's priced per mailbox slot, so costs climb as your operation grows. For an agency or a sales team running real cold outreach at volume, that trade is usually worth it.
Getting Started
- Sign up at mailforge.ai and create a workspace for your project or your first client.
- Buy the domains you need, or transfer ones you already own into the app.
- Add mailbox slots and let Mailforge set up the DNS records, or connect pre-warmed domains and mailboxes.
- Connect your sending software, such as Salesforge, and point it at the mailboxes.
- Launch your first sequence and monitor inbox placement so you can adjust volume before issues snowball.

Key features
Free Automated DNS Setup
For every domain you add, Mailforge configures DMARC, SPF, DKIM, and custom domain tracking following industry best practices. That's the part most people get wrong by hand and the reason cold mail gets blocked. The value isn't the click saved; it's not having to know what a DKIM record is. If something breaks, the Helpdesk and chat support cover the technical side.
Pre-Warmed Domains and Mailboxes
You can start sequences right away with pre-warmed domains and mailboxes rather than sending your first emails from a cold, unauthenticated setup. Warming is what builds the sender reputation that inbox providers check before deciding where your mail lands. Skipping it is one of the fastest ways to get a new domain flagged, so having it handled by default removes a common early mistake.
Bulk DNS Updates
When you run many domains, editing records one at a time doesn't scale. Mailforge lets you update DNS records across multiple domains in a few clicks inside the app. For an agency managing dozens of client domains, that turns an afternoon of registrar work into a couple of minutes, and it cuts the chance of a typo slipping into a record.
Multiple Workspaces
Workspaces let you keep projects or clients separate, then move domains and mailboxes between them as your work shifts. An agency can give each client its own space so one client's sending never touches another's reputation. The structure matters most once you're past a single campaign and juggling several at once.
Works With Any Sending Software
Mailforge is infrastructure, not a sequencer, so it's built to plug into whatever you send with. It works with Salesforge and any other sending software, which means you're not locked into one tool for the whole stack. If you already have a sequencer you like, you keep it and just swap the mailboxes underneath.
SSL and Domain Masking
This add-on displays branded websites without revealing your primary domain, and it runs alongside SSL for secure redirection. The point is privacy and safety at scale: prospects see a clean branded page while your core domain stays hidden. It's priced per domain, so you only pay for the ones you mask.
Pros and cons
Pros
- Automated DNS setup removes the technical work that trips most people up, so you can send within minutes.
- Prices start around $2 - $3 per mailbox a month, well under what Google Workspace or Microsoft 365 cost per seat.
- Pre-warmed domains and mailboxes let you launch right away instead of burning weeks on warming.
- Support is fast and responsive, which several customers call out as better than rival tools.
- It works with any sending software, so you keep your existing sequencer if you have one.
Cons
- There's no free trial. You have to buy at least some domains and mailbox slots before you can send anything.
- It's infrastructure only. If you don't have a sending tool like Salesforge, outreach doesn't happen until you add one.
- Costs scale with size because you pay per mailbox slot, so a large operation adds up quickly.
- You're renting infrastructure, not owning it. If a provider stays down, your campaigns sit idle.
