Emails going to junk only on personalized outlook email address
Hi,
I am using the MailGun API, I've begun sending regular emails to users of my web service. All was well until a user with an personalized outlook email (of my company).
Email was received with SCL 5, but emails to the regular @outlook.com address were received with SCL 1. Also emails were successfully received on gmail, etc.
Maybe the email headers will help determine why this is happening:
