How to Integrate Resend with Strapi 5 for Email Delivery

Step 1: Set Up Your Strapi Project

1. Install Strapi First, set up your Strapi project by running the command below:

1# npm
2npx create-strapi@latest
3
4# yarn
5yarn create strapi
6
7# pnpm
8pnpm create strapi

2. Start Strapi Development Server After installation, start your Strapi development server using the command below:

1# npm
2npm run develop
3
4# yarn
5yarn develop

3. Register an Admin User After starting your Strapi development server, proceed to create a new admin user.

Step 2: Create a Resend Account

Navigate to Resend and create a new account.

Step 3: Create a Resend API Key

To send your first email, you need a Resend API key. You will be asked to add one during your onboarding, or head over to https://resend.com/api-keys to create one.

Step 4: Update .env File

Update your environment variable file .env by adding the following variables:

1RESEND_API_KEY=YOUR-RESEND-API-KEY
2RESEND_DEFAULT_EMAIL=onboarding@resend.dev
3RESEND_USER_EMAIL=YOUR-RESEND-EMAIL-ADDRESS

• RESEND_API_KEY represents your Resend API key.
• RESEND_DEFAULT_EMAIL represents the email provided by default by Resend, which is onboarding@resend.dev.
• RESEND_USER_EMAIL represents the email you used in creating your Resend account.

Step 4: Install Resend Email Provider

Run the command below to install the Resend email provider from the Strapi plugins marketplace:

npm i strapi-provider-email-resend

Step 5: Update Strapi Plugin Configuration File

Locate the Plugin configuration file server/config/plugins.ts and update it with the following:

1// Path: 
2module.exports = ({ env }) => ({
3  email: {
4    config: {
5      provider: "strapi-provider-email-resend",
6      providerOptions: {
7        apiKey: env("RESEND_API_KEY"), // Required
8      },
9      settings: {
10        defaultFrom: env("RESEND_DEFAULT_EMAIL"),
11        defaultReplyTo: env("RESEND_USER_EMAIL"),
12      },
13    },
14  },
15});

Restart your development server after updating your configuration file.

Head over to Settings > Email > Configuration. You should see the plugin configuration data you created above.

Step 6: Test Resend in Your Strapi App

1. Testing in the Admin Panel To test your Resend email provider plugin, navigate to Settings > Email > Configuration.

Inside the Recipient email field, enter the email you used when creating your Resend account and click the "Send test email" button.

If you get the success toast notification as shown above, then you have successfully integrated the Resend email provider in your Strapi application.

2. Testing in your Strapi Backend Code

For this example, let's use the bootstrap() lifecycle function to send an email.

Locate the ./src/index.ts file and add the following code:

1import type { Core } from "@strapi/strapi";
2
3export default {
4  /**
5   * An asynchronous register function that runs before
6   * your application is initialized.
7   *
8   * This gives you an opportunity to extend code.
9   */
10  register(/* { strapi }: { strapi: Core.Strapi } */) {},
11
12  /**
13   * An asynchronous bootstrap function that runs before
14   * your application gets started.
15   *
16   * This gives you an opportunity to set up your data model,
17   * run jobs, or perform some special logic.
18   */
19  bootstrap({ strapi }: { strapi: Core.Strapi }) {
20    const sendTestEmail = async () => {
21      await strapi.plugins.email.services.email.send({
22        to: process.env.RESEND_USER_EMAIL,
23        text: "Hello Theodore! Testing Resend and Strapi integration ",
24        subject: "Testing Resend Provider",
25      });
26    };
27
28    sendTestEmail();
29  },
30};

After adding the code above to your lifecycle function, check your email inbox.

👋 NOTE The code above runs every time you start Strapi. So, ensure you remove the sendTestEmail function as we only used it for testing.

Congratulations! You have successfully integrated Resend and Strapi!
