Very likely. I suggest you study the subject.
You can attempt to 'clean' the emails to make them less spam-like.
Plain text rather than html if possible.
Ensure all the correct headers with valid return addresses are present.
This is a huge subject, similar to writing web-pages that score with search engines.
One word can make all the difference
