# Mailforge

Mailforge sells cold-email infrastructure: it registers domains, creates mailboxes on a shared IP pool and sets up DNS (SPF, DKIM, DMARC) automatically. Website: mailforge.ai. Category: [Email Infrastructure & Verification](https://gtmranked.com/best/email-deliverability/). Not enough independent evidence to rank (4 rated comments).

**Verdict:** Independent discussion is thin: only four comments carry a first-hand opinion, one positive (no deliverability issues, easy setup) and the rest negative, the most substantive being a 2024 report of Mailforge mailboxes getting thrown out of Instantly and Smartlead warmup pools. About half of the 24 comments are promotional: posts from the vendor and the Salesforge and Mails.ai side, two near-identical comments calling Mailforge garbage while plugging another sender, an affiliate-link list, a sister-product stack plug, and pitches from MailReach's founder and a competing mailbox seller. The recurring claim that shared-pool providers lag Google Workspace comes almost entirely from those promotional accounts, so it is not treated as evidence here.

**What users like:**
- One agency user reports no deliverability problems and an easy setup [1](https://www.reddit.com/r/agency/comments/1g01mb4/_/m0eps74/)

**What users complain about:**
- Mailboxes were ejected from Instantly and Smartlead warmup pools, which the user blamed on the MailChannels relay behind Mailforge (2024 report) [1](https://www.reddit.com/r/SaaS/comments/19eavrw/_/l7wjgza/)

**Best for:** Agencies that want domains, DNS and mailboxes set up quickly and will test placement themselves.
**Skip it if:** Senders who depend on Instantly or Smartlead warmup pools.
**Pricing (vendor-stated, checked 2026-10-14):** Usage-based: $3 per mailbox slot per month, minimum 10 slots, with 2 months free on annual billing; .com domains $14/year each; optional SSL and domain masking at $2 per domain per month. No free plan or trial; no contract.
