The more emails are sent, and the less the emails are marked as spam, the better we have a good reputation on the internet. We don’t want your emails to end-up in the junk/spamfolder, or worse: end up in the quarantine folder in the mailserver. Office365 is one of the providers which put emails in the quarantine folder and no one will see them if the email doesn’t apply to the mail-protocols of Office365. We want of course to avoid that!
Thats why we do an analyse of your emails (but we don’t look at the content of the emails) to see if the emails are following the rules of the mail-protocols.
