Good Prathamesh, thanks for answering,
It is exactly what we did, we requested the elimination of the blacklists, and we always had a static IP address, because our blog is hosted on a dedicated server.
Now we have the plugin disabled, because if we activate it again it will send the emails and we will go back to the blacklists.
I think the problem is sending mass emails, since in addition to sending emails to those who subscribed, it also sends me, it’s like doubling the amount of emails sent: 100 to my subscribers and 100 to me.
These 100 that come to me, are to the same email, that is to say to the same account, to my account, that’s why it can be considered SPAM.
I would like to know how to disable the Cron notifications that come to my email, I use a bit of PHP, maybe if you could help me please!
Regards!
