Custom Domain Emails Being Treated as Spam
Hello all,
I have a custom domain from GoDaddy that I setup using Zoho so that I can send e-mails from myname at customdomain.club. I set up DKIM, SPF and DMARC records on my custom domain and used mail-tester.com and received a score of 10 and it says these are correct.
My problem is that any emails I send from this custom domain get treated as spam, but mainly by hotmail.com. If I run my spam email headers through the mxtoolbox's Spam Analyzer, it gives me 5.6/5.0 rating which it classifies as spam. Most of my points are lost due to lack Message-Id, Subject, To, From and Date headers which is odd because I can see them in the e-mail message I copied to Spam Analyzer.
Content analysis details: (5.6 points, 5.0 required)

1.8 MISSING_SUBJECT Missing Subject: header
0.0 UNPARSEABLE_RELAY Informational: message has unparseable relay lines

What can I change in Zoho to make sure that these are included correctly so my e-mails are treated as spam?
