Emails not received when a new users is subscribed

[OptimusBain]

Hello,

I am having problems with emails. When a new user is subscribed, he will not receive any emails at all. This started a couple of weeks ago, and I didn't realize it until now.

I've tried to register, but I will never get an email. It did work before when I had SendGrid integrated, but since I turned SendGrid off, no emails have been received. I do not understand because I can send emails from the email used as the admin when I use Gmail. By the way, my doing has emails managed by Google.

Is there a way to know what is going on? Users cannot confirm their subscriptions, and it's creating a lot of problems 😞

Could it related to DKIM or similar? I can send/receive emails from the same email uses in ACP as an admin, but as an admin, ACP will no longer send emails and all users are tags and unconfirmed and they will never be able to subscribe.

Thanks a lot

Have you checked your sent mail to see its actually been sent? Also, have you checked your domain to ensure you haven't been blacklisted anywhere?
