These instructions are for Cypress v3 which is not the latest version of Cypress. In Cypress v4, you can configure email settings by navigating to Admin > Application Settings > Edit Application Settings .

Mailer setup instructions:

1. Set up your email account.

   • Any email account with an SMTP server will work (Gmail, Outlook, etc.).
   • We'll use Gmail for this tutorial.
   • If you're using a Gmail account, it works best with 2 Factor Authentication turned on; this helps the mailer work with some Gmail security settings.

2. Open <app_directory>/config/cypress.yml on the server in your favorite text editor.

   • This file will allow you to set the mailer settings; setting mailer settings through the web admin pane is currently not supported (settings changes will not be persisted to disk)

3. In the website_domain and website_port fields, replace <%= ENV["WEBSITE_DOMAIN"] %> with the URL of your Cypress instance (hostname or IP address), and <%= ENV["WEBSITE_PORT"] %> with the port the webserver is running on (usually 80).

4. In the mailer_address field, replace <%= ENV["MAILER_ADDRESS"] %> with the URL of your SMTP server.

   • In Gmail, the mailer_address is smtp.gmail.com

5. In the mailer_port field, replace <%= ENV["MAILER_PORT"] %> with the port for the SMTP server.

   • If you're using Gmail, this will be 587, the port for TLS/STARTTLS access to the SMTP server.
   • Use of TLS/STARTTLS is recommended for security reasons.

6. In the mailer_domain field, replace <%= ENV["MAILER_DOMAIN"] %> with the email address domain.

   • For example, [email protected]'s mailer_domain value would be gmail.com

7. In the mailer_user_name and mailer_password field,s replace <%= ENV["MAILER_USER_NAME"] %> with the username for the email account, and <%= ENV["MAILER_PASSWORD"] %> with the email account password.

   • For [email protected], the username would be foo
   • If you're using Gmail with 2 Factor Authentication, the password should be an "App Password". If you're not using 2 Factor Authentication, be sure to enable access by less secure apps

8. Save cypress.yml.

9. Restart the Cypress server.
