Message format in spam check

When I try to send some emails the spam check reads " * Message Format: Fill in a short form with personal information". What does this mean and how can I fix this spam issue?

I just came across this issue. The email had the phrase “phone and email address” in it. I changed it to contact information and I was good to go. If you have a similar phrase in your email, try replacing it.
Hopes this helps :slight_smile:
