Where Mailgun is strong
Mailgun has a rich HTTP API, inbound email routing and parsing, an email validation product, and regional (EU) sending. If inbound processing or address validation is central to your app, those are genuine strengths.
Where Mailer To Go is different
- DNS you don’t manage. One delegated NS record and we publish and auto-rotate SPF/DKIM/DMARC — no record juggling. Details.
- Reputation isolation on a dedicated subdomain by default.
- Config-var-native on Heroku, Addons.io, and Build.io.
- Focused transactional sending rather than a broad toolkit to assemble.
The honest trade-off today: Mailgun’s REST API is mature; ours is in development, so you send over SMTP — which works from any language (quickstart).
