Mailboundry vs Mailforge
Mailforge is a distributed infrastructure product: cheap, fast and sharing IPs with everyone else in the pool. Mailboundry gives every mailbox an IP nobody else touches.
VS
Which one fits your sending
Choose Mailboundry if
- Every mailbox sends from a dedicated IP, so your reputation is yours alone
- A bad campaign is contained to one IP instead of degrading a whole pool
- Outreach, lead data and reply handling are included, not a second subscription
Choose Mailforge if
- You are testing cold email for the first time and want the lowest possible entry cost
- You expect a high spam-complaint rate and would rather not put it on your own IP
- You want to borrow an established pool reputation instead of building your own
Both give you
- Domains bought and configured in-app
- Automated SPF, DKIM, DMARC and MX
- SSL and domain masking
- Bulk mailbox creation
- API access

100 mailboxes, both ways
A hundred mailboxes is where per-mailbox pricing stops being an abstraction. Domains are extra on both sides.
100 mailboxes at $2.30 on annual billing, each with its own dedicated IP, plus domains at $8–$14 a year.
100 mailbox slots at about $2 on annual billing, on shared pool IPs, plus roughly $14 per domain per year.
Three reasons that decide it
The $0.30 question
At 100 mailboxes the gap is roughly $30 a month. That is what a dedicated IP per mailbox costs you here: the difference between a reputation you own and one you rent from strangers.
Isolation you can prove
When placement drops on a shared pool you cannot tell whether it was your copy, your list or somebody else’s. On dedicated IPs the answer is always in your own sending data.
Not another subscription
Mailforge is infrastructure only; you still buy a sequencer. Mailboundry is part of Outboundry, so mailboxes, campaigns, LinkedIn, lead data and replies live in one place.
