Build with SendGrid

Build applications that use SendGrid

Evonx does not claim an official SendGrid partnership. Use this guide to wire transactional email—receipts, invites, password resets—through SendGrid from applications you generate and operate.

What SendGrid is

SendGrid is an email delivery platform for transactional and marketing messages with SMTP and Web API access.

Evonx helps you build applications that use SendGrid APIs — this page does not claim an official partnership unless one is explicitly stated.

What you can build

  • Transactional email from product events
  • Template-driven notification systems
  • Bounce and complaint webhook handlers
  • Digest and report email jobs

Application types

SaaS

Marketplaces

Internal tools

Technical considerations

  • Authenticate domains and align SPF/DKIM before production
  • Handle webhook events for bounces and spam reports
  • Keep API keys in server environments only

FAQ

Should marketing and transactional mail share one SendGrid subuser?

Many teams separate them so a marketing reputation issue does not block password resets.

How do we suppress emails to bounced addresses?

Process SendGrid event webhooks and mark contacts unmailable in your database.

Can we use dynamic templates from the app?

Yes—store template IDs and pass substitution data from your domain events.

Build production software with Evonx
