The problem shouldn't be in your domain, it should be some words in your email.
1. change your subject
2. delete a part of your email and test it again, if it still goes into spam folder, restore that part, then delete another part and test again
3. sometimes there are domain names that counted as spam, so if you write a web address in your email, try to remove it and test it again
Hope that's help
