What is peoples experience with keeping lists inside mautic active enough that you dont get blocked for high bounce/unsubscribes?
I found I had accidently been drip feeding my failed contact form requests into my mailing list, and when I tried to restart sending email after a few month break, I was hit by too high fail rate, from SparkPost api.
I can understand it is good to keep active, just wondered if there was any practice or rules people work on to keep that way? Or just a life lesson for me.
Now need to prove I have cleaned up the list to SparkPost so they will enable the account again. So need to try a checking service.
