Mailboundry vs Infraforge
Both sell dedicated-IP infrastructure. The difference: IP cost, billing terms, and whether outreach is included.
VS
Which one fits your sending
Choose Mailboundry if
- A dedicated IP is included with every mailbox, not a $99/month server add-on
- Monthly billing is available, so you can size your estate to actual pipeline
- Sequencing, LinkedIn, lead data and the unified inbox are in the same subscription
Choose Infraforge if
- You want pre-warmed domains and mailboxes handed over on day one
- You are already committed to the Salesforge stack and want one login across it
- You prefer buying IP addresses as discrete server units you control directly
Both give you
- Private infrastructure rather than reseller seats
- Automated SPF, DKIM, DMARC and MX
- SSL and domain masking
- Bulk DNS across a domain fleet
- API access
- Whitelabel for agencies

100 mailboxes, both ways
A hundred mailboxes is where per-mailbox pricing stops being an abstraction. Domains are extra on both sides.
100 mailboxes on annual billing at $1.50 each. A dedicated IP option per mailbox is included; domains are $8–$14 a year.
100 mailbox slots at $3 on annual billing, plus $99 a month for one dedicated-IP server, plus $14 per domain per year.
Three reasons that decide it
Dedicated IPs are the product, not an upsell
On Mailboundry the dedicated IP is the default, $1.40–$2.00 a mailbox. Extra IPs $50 a month.
Monthly billing when volume moves
Volume is seasonal. Mailboundry bills monthly, quarterly or annually, not quarterly-and-up only.
One subscription instead of a stack
Infraforge is one of several Forge products. Mailboundry ships inside Outboundry: one bill, one login.
