Spam analysis is tricky since it depends on a lot of different factors - message content, mail server configuration, your IP address, and so on.
One awesome tool I use to check my emails is mail-tester.com/. It's a free tool that gives you a temporary email address where you can send one of your emails. The service will then process the message and calculate a score with a report on what's okay and what's potentially causing your messages to fall into spam. I've caught a lot of small issues on some messages that fixed a lot of spam issues for me.
It's not perfect since mail servers process spam differently. But this tool will point you in the right direction to catch most major problems.
