Hello Michael
In the last weeks we had requests from customers, whose "newsletter" via sendinblue could not be delivered to us. In the logs I see at the given time, that the IP of sendinblue was on the blacklist of spamcop.net. That is, the mails were rejected by us.
The customer now says the mails go through everywhere else (I'm looking at you bluewin.ch), just not with you.
we're actively blocking many of their servers due to sending our customers spam, so that will invalidate that "everywhere else" statement a bit;)
Cheers, Markus
