Email Notifications

Build production-ready email systems with proper deliverability, bounce handling, and template management.

Core Integration Patterns

SendGrid Setup

// BAD: API key in code, no error handling
import sgMail from '@sendgrid/mail';
sgMail.setApiKey('SG.abc123...');
await sgMail.send({
  to: user.email,
  from: 'noreply@example.com',
  subject: 'Welcome',
  html: '<h1>Welcome!</h1>'
});
