Description
Resend for WordPress routes your site’s transactional and marketing emails through the Resend API, replacing the default WordPress mail delivery method.
Key Features:
- Simple Setup – Connect your Resend account with just an API key
- Email Delivery – Routes outgoing WordPress emails through Resend’s infrastructure
- Transactional Emails – Perfect for password resets, notifications, confirmations, and more
- Easy Configuration – Set sender name and email directly from WordPress settings
- Test Emails – Send test emails to verify your setup works correctly
How it works:
The Resend plugin overrides WordPress’ native wp_mail() function and routes all emails through the Resend API. This means any email sent by WordPress (password resets, notifications, contact forms, etc.) will be sent through Resend instead of your server’s default mail handling.
Getting Started:
- Create a free account at Resend.com
- Generate an API key in your Resend dashboard
- Install and activate the Resend WordPress plugin
- Paste your API key into the plugin settings
- Configure your sender name and email address
- Test with our built-in test email feature
Requirements:
- WordPress 5.8 or higher
- PHP 7.2 or higher
- A Resend account (free tier available)

External services
This plugin requires a Resend account and relies on the Resend API (a third-party transactional email service) to deliver emails.
This plugin replaces WordPress’s wp_mail() function. Every email your site sends (password resets, notifications, contact form submissions, and any other message triggered through wp_mail()) is transmitted to the Resend API instead of being sent directly by your server. Each time an email is sent, the plugin sends the following to Resend: the recipient address(es), sender name and email address, subject, message body (HTML or plain text), and any file attachments.
This service is provided by Resend: Terms of Service, Privacy Policy.
