Our take on Infraforge
Infraforge is the dedicated-IP, private-SMTP tier of the Salesforge family. It markets mailboxes that arrive with warmup already completed, sets up in around five minutes with automated DNS, and includes an API on all plans — positioning itself as the “avoid the shared pool” upgrade over sibling product Mailforge, at roughly $3–$4/mailbox depending on volume.
Dig in and a few questions surface. It's custom SMTP infrastructure, not Google or Microsoft, so deliverability behaves differently. Independent reviews are sparse, and because Salesforge owns the ecosystem, much of the comparative “review” content ranking Infraforge well is effectively its own SEO. A separate $99/month dedicated-IP add-on also suggests the base tier may not give every mailbox a truly dedicated IP despite the marketing. With no free trial, you can't verify the warming or placement claims without paying first.
