Hello, I'm trying to send a newsletter everything seems OK from the dashboard (notification that the is successfully sent when using the send test function, but can't see the mail in my mailbox!

Thanks for your help),

Hi,

That could be caused by a number of reasons. Do yoiu have more details on how you have configured your send process and if Wordpress itself is using the same configuration to send system mails like on account creation and forgot password??

I have similar issues. I was getting this in Starter version, I bought Essential with some hopes. But I am getting the same following errors. I am not sure how to fix it - tries PHPmailer and SMTP both have failed:

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

If you receive this message, that means your configuration is Ok

Not sure to fix it.
