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.
