Introduction

Managing subscribers and unsubscribers is a critical part of any email implementation. It’s important to respect your users’ preferences and ensure that they’re receiving the right emails at the right time.

Resend Audiences allow you to group and manage your contacts in a simple and intuitive way.

Import Contacts

You can add your Contacts to an Audience in 3 different ways: manually, CSV upload, or via API.

Instead of manually importing contacts, you can also add them programmatically.

You can leverage one of the Resend SDKs (PHP, Python, Ruby, Go, Java, and cURL) to add contacts to your audience.

Here are the links to the Audience and Contacts API References.

Example using the Node.js SDK:

import { Resend } from 'resend';

const resend = new Resend('re_123456789');

resend.contacts.create({
  email: 'steve.wozniak@gmail.com',
  firstName: 'Steve',
  lastName: 'Wozniak',
  unsubscribed: false,
  audienceId: '78261eea-8f8b-4381-83c6-79fa7120f1cf',
});

Send emails to your Audience

Audiences were designed to be used in conjunction with Broadcasts.

You can send emails to your Audience by creating a new Broadcast and selecting the Audience you want to send it to.

Send emails to your Audience

You can include the Unsubscribe Footer in your Broadcasts, which will be automatically replaced with the correct link for each contact.

Automatic Unsubscribes

When you send emails to your Audience, Resend will automatically handle the unsubscribe flow for you.

If a contact unsubscribes from your emails, they will be skipped when sending a future Broadcast to this same audience.
