Short answer: E-Warmup is cheaper, includes more inboxes, sends more daily volume, and offers a Free Forever plan. Mailwarm has no free trial and starts at $79/month for a single inbox.
Mailwarm Starter: $79/month, 1 inbox, 50 emails/day. No free trial or plan. E-Warmup Basic: $49/month, 2 mailboxes, 150 emails/day. Free Forever available before paying.
Three differences matter:
Daily volume. E-Warmup Basic sends 3x the warmup volume at a lower price point, meaning faster reputation building.
Feature stack. E-Warmup includes inbox placement testing, AI-adaptive warmup content, sender reputation monitoring, AI-powered blacklist removal, and warmup bounce protection. Mailwarm uses fixed warmup patterns and offers none of these.
Scale economics. Mailwarm Scale (10 inboxes): $479/month. E-Warmup Premium (5 mailboxes + add-on): $189. The gap widens with team size.
Mailwarm's Y Combinator backing carries weight with some buyers. Their free tool library (spam checker, SPF/DKIM/DMARC generators) is also genuinely useful even outside their main product.
