Mailforge vs Infraforge: Both Salesforge Products Compared
Mailforge and Infraforge are both Salesforge products but target different teams. Distributed vs private infrastructure, pricing, and when to pick each.
Two Products, One Parent Company
Salesforge operates both Mailforge and Infraforge as separate cold email infrastructure products. The confusing part: many buyers don't realize they're comparing two products from the same company. The practical question isn't "which is better," it's "which fits your scale and budget."
Mailforge positions as the distributed infrastructure option at accessible pricing. Infraforge positions as the private infrastructure option for teams willing to pay premium for dedicated setups. Here's the breakdown.
Core Architectural Difference
Mailforge uses a distributed infrastructure model. Multiple customers share the underlying infrastructure layer while each gets dedicated inboxes. This model reduces cost per inbox but introduces shared-reputation risk if other customers on the same infrastructure make mistakes.
Infraforge uses a private infrastructure model. Each customer gets dedicated infrastructure allocated specifically to them. Higher cost. Lower shared-reputation risk. Designed for higher-volume operations where infrastructure isolation matters.

- More customization options
Infraforge Weaknesses

When to Pick Mailforge
You're running fewer than 50 inboxes, your volume is modest (under 500 emails per day), and pricing matters more than infrastructure isolation. The shared infrastructure risk is real but manageable at low volume.
When to Pick Infraforge
You're running 100+ inboxes, high daily volume, and you can't afford reputation spillover from other customers. The premium pricing is justified when you're generating enough pipeline to make infrastructure isolation a worthwhile investment.
Puzzle Inbox as Alternative
Puzzle Inbox offers dedicated Google Workspace and Outlook 365 inboxes starting at $0.35 per Outlook inbox and $3 to $4.50 per Google inbox. Pre-warmed options included. WhatsApp support responds in under 15 minutes.
Compared to Mailforge: lower price for pre-warmed Google inboxes, Outlook option (which Mailforge has in limited form), faster support.
Compared to Infraforge: significantly lower pricing for dedicated inboxes, similar deliverability on properly configured infrastructure.
