Step 10. How to use my gmail.com email to send messages in UNA
When i use the Contact form on my website, it fails to send the form, and i get an email on my gmail with the following message:
Sign-in attempt was blocked
Someone just used your password to try to sign in to your account from a non-Google app. Google blocked them, but you should check what happened. Review your account activity to make sure no one else has access.
