In order to send emails from your Hudu, you will need to provide an SMTP server.
If you are looking for a free (for the number of emails Hudu has to send out), easy-to-set-up one, we recommend SMTP2GO.
You can test the SMTP connection by going to the Hudu admin >> Self-Hosting Center >> SMTP Test when logged in to your instance.
Example
Provided below are some example credentials for different providers.

- With Gmail, try turning on 2-step validation and using an application password.
- Alternatively, enable less secure apps to access the account.
