About this tool

SendGrid is a cloud-based email delivery service owned by Twilio. It handles transactional emails (password resets, order confirmations) and marketing campaigns at scale through a REST API and SMTP relay. For developers who don't want to maintain their own email servers, SendGrid is the most widely adopted solution after Amazon SES.

Pros

  • +Free tier: 100 emails per day forever, no credit card required
  • +Both REST API and SMTP relay — use whichever fits your stack
  • +Built-in analytics: open rates, click tracking, bounce rates, spam reports
  • +Dynamic templates with a visual editor and handlebars-style substitution
  • +Dedicated IP addresses available on paid plans for better deliverability
