Full breakdown of Mailforge pricing per mailbox, the shared IP trade-off, and how it compares to InboxKit and other infrastructure providers.

2 min readUpdated Mar 2026

Bottom line

Mailforge charges $2 to $3 per SMTP mailbox on shared IPs. At 200 mailboxes, that is roughly $484/mo versus $1,680 for direct Google Workspace. Competitive pricing, but no warmup, no verification, and shared IPs.

InboxKit at $2.50/mailbox offers Google Workspace with all deliverability tools for a similar price.

What's Not Included

Shared IP risk

Mailforge uses shared IP infrastructure. Other senders on your IP pool can affect your deliverability. This is not a direct cost, but it can impact results. For dedicated IPs, you would need to upgrade to Infraforge at $3-$4/mailbox plus $99/mo.

Indirect (deliverability risk)

No warmup or deliverability tools

You need warmup, verification, and monitoring from your sending tool. SendKit includes all of these. If using a platform without built-in deliverability tools, budget for standalone services.

Infraforge upgrade for dedicated IPs

How Mailforge Pricing Works

Mailforge charges $2 to $3 per SMTP mailbox per month on shared IP infrastructure. No base fees, no tiered pricing. The rate varies based on volume and configuration.

SSL and domain masking are included. Mailforge advertises that 200 mailboxes cost approximately $484/mo, compared to $1,680 for Google Workspace directly. That is a 71% savings on raw mailbox cost.

Key takeaways

  • $2-$3/mailbox on shared IPs, no base fees
  • 200 mailboxes: ~$484/mo (71% cheaper than direct GWS)
  • SSL and domain masking included
  • Bulk DNS updates and domain transferring available

Mailforge vs InboxKit Pricing

At 200 mailboxes, Mailforge costs roughly $484/mo. InboxKit costs $500/mo. The $16 difference is negligible.

But InboxKit includes Google Workspace mailboxes (vs SMTP), US-based IPs, built-in warmup, inbox placement testing, email verification, and blacklist monitoring. For $16 more per month, you upgrade from shared IP SMTP to Google Workspace with a full deliverability stack. That makes InboxKit the better value for teams that care about inbox placement.

Key takeaways

  • 200 mailboxes: Mailforge ~$484/mo vs InboxKit $500/mo
  • $16/mo difference for GWS, US IPs, warmup, verification, and monitoring
  • InboxKit is the better value when deliverability tools are factored in
