Automatic Unsubscribes

When a contact unsubscribes, Resend will automatically handle the unsubscribe flow for you, and they will be skipped when sending the next Broadcast.

Code Integration

Integrate your audience with code

Add the logic to create, update, unsubscribe, and remove contacts directly into your application.

import { Resend } from 'resend';


const resend = new Resend('re_123456789');


resend.contacts.update({
  id: '520784e2-887d-4c25-b53c-4ad46ad38100',
  audienceId: '78261eea-8f8b-4381-83c6-79fa7120f1cf',
  unsubscribed: true,
});
