Overview
Mailforge is shared, distributed email infrastructure for cold outreach, from the same Forge stack as Infraforge and Primeforge. Mailbox slots start at $3 per month, billed yearly, with a 10-slot minimum. Monthly billing is higher: 25 slots cost $75 per month monthly versus $60 per month yearly..com domains are $14 per year. Subscription covers automated DNS, hosting, and maintenance. You can cancel anytime. SSL and domain masking is $2 per domain per month, or $6 per domain billed yearly.
Teams pick Mailforge when they want Gmail-like shared IPs instead of a private server. The vendor says it is the better Forge option if you expect spam reports. There is no free trial; you can open the app without domains. Mailforge, Infraforge, and Primeforge each need their own subscription. Slots are capacity, so unused slots still bill. Native sequencer names are not printed beyond the wider Forge stack.
