email webhooks for app

If you want email webhooks for your app, there are two common meanings:

1. Send email when an event happens in your app
   Example: user signs up → your app triggers a webhook → email is sent.

2. Receive events from an email provider
   Example: Mailgun/SendGrid/SES sends your app a webhook when an email is delivered, bounced, opened, etc.

Typical setup

• Your app emits an event
• A webhook endpoint receives it
• A worker/service sends the email via a provider like:
  • SendGrid
  • Mailgun
  • Amazon SES
  • Postmark
  • Resend

Example flow

• User places order
• Your app calls POST /webhooks/order-created
• Webhook handler sends:
  • order confirmation email
  • invoice email
  • internal notification

If you mean inbound email webhooks

Use your email provider’s webhook feature to handle:

• delivered
• bounced
• opened
• clicked
• spam complaint
• unsubscribed

Basic design tips

• Verify webhook signatures
• Make webhook handlers idempotent
• Queue email sending jobs
• Retry failures
• Log webhook payloads for debugging

If you want, I can help with one of these:

• a Node.js email webhook example
• a Laravel / Python / Django / Next.js implementation
• choosing the best email provider
• designing the API schema for webhook events
