Hi, apart from the validation of the domain (spf, dkim ...) what other tricks or recommendations do you have to prevent a campaign from sending?

At some point I will read some special labels on the images.

Your campaign's content should be free from spam words like "free, offers".

You can see on mail-tester about Score and try to improve it.
