To test if your e-mail configuration works you can go to Status > Events Log > Events Reporting create new rule with Send e-mail option, configure it and click on "Send test email" button to see if you are receiving them.
Few pointers for configuration:
1. In your email settings (not Router, but e-mail, as in google, yahoo etc.) enable option that lets "less secure devices" to log in to your email
2. Most emails uses ports 587 (TLS required) and 465 (SSL required), use 587 or equivalent for your's email.
3. In WebUI configuration User name, Sender's email address and Recipient's email address should be same email e.g. Henrik@gmail.com
