MailChannels
Pros
- + Solves the shared-IP reputation problem for multi-tenant hosts — one compromised account no longer gets the whole network blocklisted
- + Published, volume-based pricing with a free Email API tier of 3,000 emails per month
- + Long track record since 2004 with named large hosts (DreamHost case: email tickets from ~300/week to ~10)
- + Compromised-account detection and spam-trap handling built for hosting abuse patterns, not generic sending
Cons
- - Starter tier excludes API, webhooks, and the cPanel plugin — practical integrated entry is Standard at $524.99/month
- - No published uptime SLA and no 24/7 support line on any tier
- - Shared IP pools only; dedicated IPs are not a standard option
- - B2B pricing and product scope make it a poor fit for individual developers and small senders
Mailcow
Pros
- + Free GPLv3 suite with the full mail stack (groupware, ActiveSync, Rspamd, ClamAV) — no seats, no volume caps
- + Specific, credible hardware requirements and detailed ops documentation
- + Active monthly release train with prompt security patches (e.g. CVE-2026-33278 fix in May 2026, forced 2FA in March 2026)
- + Vendor-backed escape hatches: shared mailcow from EUR 8.90/mo and managed mailcow from EUR 54.90/mo in Germany
Cons
- - Needs real server management skills (Docker, DNS, PTR, firewall chains, updates)
- - 6 GiB RAM minimum rules out the cheapest VPS tiers
- - IP reputation and deliverability are entirely self-managed on the free tier
- - Community-only support with no SLA behind the open-source software
