I set up a plugin on WordPress to send messages to users, but when I try to send a test e-mail I receive a message of this type:
Blocked login attempt Hello! Someone just tried to log into the account name@gmail.com through an insecure application.
I’ve been reading on the off site about various problems with this and that you need a paid Google Apps account, but I don’t understand what’s really true, don’t tell me what to do?
Thank you for attention!
