### Configuations for sending emails using Sendgrid
An easy and free STMP service to set up is [Sendgrid](https://sendgrid.com/), the free tier allows for up to 100 emails per day to be sent. In the settings below you can provide any email for `matrix_mailer_sender_address`.
The only other thing you need to change is the `matrix_mailer_relay_auth_password`, which you can generate at https://app.sendgrid.com/settings/api_keys. The API key password looks something like `SG.955oW1mLSfwds7i9Yd6IA5Q.q8GTaB8q9kGDzasegdG6u95fQ-6zkdwrPP8bOeuI`.
Note that the `matrix_mailer_relay_auth_username` is literally the string `apikey`, it's always the same for Sendgrid.
```yaml
matrix_mailer_sender_address: "arbitrary@email.com"
matrix_mailer_relay_use: true
matrix_mailer_relay_host_name: "smtp.sendgrid.net"
matrix_mailer_relay_host_port: 587
matrix_mailer_relay_auth: true
matrix_mailer_relay_auth_username: "apikey"
matrix_mailer_relay_auth_password: "<your api key password>"
```

If you're having trouble with email not being delivered, it may be useful to inspect the mailer logs: `journalctl -f -u matrix-mailer`. If you're having trouble with email not being delivered, it may be useful to inspect the mailer logs: `journalctl -f -u matrix-mailer`.
