# Email Notifications

> How to send notifications to users

Postiz supports two email providers: Resend and NodeMailer (SMTP).

If you have an email provider configured, then new users will require activation.

```env theme={null}
EMAIL_PROVIDER: "resend|nodemailer"
```

You must also set the sender name and email address for all providers as follows;

```env theme={null}
EMAIL_FROM_NAME: "Postiz Emailer"
EMAIL_FROM_ADDRESS: "postiz@example.com"
```

## Resend

Postiz uses Resend to send email notifications to users. If this key is set, users
will also require activation.

<Steps>
  <Step title="Register on Resend">
    Register to [Resend](https://resend.com), and connect your domain.
  </Step>

  <Step title="Copy your API Key">
    Copy your API Key from the Resend control panel.
  </Step>

  <Step title="Edit your .env file">
    Open the .env file and edit the following line.

    ```env theme={null}
    EMAIL_PROVIDER="resend"
    RESEND_API_KEY="<your-api-key-here>"
    ```
  </Step>
</Steps>

## NodeMailer (SMTP)

This is an alternative to Resend. You can use NodeMailer, which is simply a SMTP library, to connect to any SMTP server.

```env theme={null}
EMAIL_PROVIDER: "nodemailer"
EMAIL_HOST: "smtp.gmail.com" # smtp host if you choose nodemailer
EMAIL_PORT: "465" # smtp port if you choose nodemailer
EMAIL_SECURE: "true" # smtp secure if you choose nodemailer
EMAIL_USER: "user" # smtp user if you choose nodemailer
EMAIL_PASS: "pass" # smtp pass if you choose nodemailer
```
