Best Mailgun alternatives in 2026

Mailgun is a capable transactional email API — but the 1-day log retention on lower plans is a real pain, it's been owned by multiple companies (Rackspace, Sinch), and there's no automation layer if you need lifecycle emails. If you're looking for Mailgun alternatives with better logs, sequences, or a more developer-native experience, here's what to consider.

Why teams look for Mailgun alternatives

Log retention is only 1 day on Flex plan, 30 days only on Growth ($80/mo)

Transactional-only — no sequences, drip campaigns, or contact management

Ownership changes (Rackspace → Mailchimp → Sinch) have created product uncertainty

No BYOK — you're locked into Mailgun's sending infrastructure

EU data compliance requires upgrading to higher-tier plans for EU endpoints

Support quality has degraded since the Sinch acquisition according to many users

Amazon SES

$0.10 per 1,000 emails

Extremely cheap delivery infrastructure, but minimal features — no sequences, no contacts, minimal UI, and setup is complex. Best as a BYOK backend behind another platform like tinysend.
