Gmail: Review blocked sign-in attempt
Sending email from ProfitFab using a Google Suite (formerly known as Google Apps) Gmail account may result in an error if allowing access to less secure apps is disabled. You may also receive an email from Google with the subject “Review blocked sign-in attempt”.
If this is the case, please follow the instructions contained within the email on enabling access to less secure apps.
To manually change this setting, visit your Google account page. Find the “Connected apps & sites” section under “Sign in & security”. Scroll to the bottom and click the slider to “Allow less secure apps: ON”. If you do not see this section, you do not have sufficient rights to modify this setting. Contact your domain administrator.
