Email notifications turn Spam!

I set email notifications for new videos with Peertube on, but it puts them in the spam folder of nearly all email providers.

Regular emails from the same domain, and even peertube’s confirmation text to sign-up, do not go to spam. The Dkim, dmarc, spf, reverse dns are all setup. Is there a way to modify the « new video » email notifications so I can make them less spammy?


Can you display email source to check headers added by your antispam?
