Spam Assassin is a system used by ISP's to analyze the content in messages. Adopia has a system to analyze your content and gauge whether there will be deliverability issues with any of your messages. 

You can use Adopia's system to check your Spam Scored by first creating either a broadcast, trigger or autoresponder. After you have crafted your message click Check Spam Score

On a scale of 0-5 (5 being the highest spam level), your email's content will be gauged on whether it’s likely to end up in the inbox or 

the spam folder. Make corrections to your message based on the spam score if necessary and test until your score registers a zero.

If your score registers a zero, your message should have no issues with being delivered to the inbox.
