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
Amazon SES
Pros
- + Lowest published per-email rate: $0.10 per 1,000 emails, no plan required
- + Same-region integration with EC2, Lambda, IAM, and CloudWatch
- + Transparent pricing page covering add-ons and plan bands
- + Global Endpoints for multi-region sending resilience
- + Scales to very high volume without provisioning infrastructure
Cons
- - Sandbox start (200 messages/day to verified recipients) with an opaque production-access review
- - No marketing tooling, templates, or dashboards — it is a pipe, not a suite
- - Dedicated IPs, attachments, and deliverability add-ons inflate the real bill
- - Deliverability and IP warm-up are your responsibility
