Where SendGrid is strong
SendGrid is a mature, full-suite platform: marketing campaigns, a template editor, a large integration ecosystem, and proven scale for very high volumes. If you need marketing automation and transactional in one vendor, that breadth is real.
Where Mailer To Go is different
- Setup without DNS tickets. Delegate
mtg.yourdomain.comwith a single NS record and we publish and auto-rotate SPF/DKIM/DMARC for you. Why we do this. - Reputation isolation by default on a dedicated sending subdomain.
- Config-var-native on Heroku, Addons.io, and Build.io — provision and the credentials are just there.
- Focused and simpler — transactional done well, not a sprawling suite to configure.
The honest trade-off today: SendGrid has a mature REST API; ours is in development, so you send over SMTP (which works from every language — see the quickstart).
