Hello,
Is it possible that a website gets penalised by Google because your hosting company blocked you from sending emails?
Basically I got a message from my hosting company saying that they were blocking me from sending emails from our server and domain because too many had mistakes or were complained about.
The same day we dropped from 2<sup>nd</sup> on a keyword to about 600<sup>th</sup> while still being ranked for other keywords. The drop was for our main keyword.
Can the fact we sent “bad emails” be related to a rank drop?
For the record, those were confiormation emails for account creation, they were legit, not spam. That's off-topic though.
