Overview

Reliable SMTP relay and email API with a permanent free tier

Key Features

SMTP2GO doesn't get talked about nearly as often as SendGrid or Mailgun, which is a little unfair given it's been quietly running mail for small businesses and developers for well over a decade. It's privately held, hasn't chased the venture-funded growth-at-all-costs path that shaped a lot of its competitors, and the product reflects that: fewer flashy features, more just making sure your email gets delivered and you can find someone to talk to if it doesn't.
