What you could do, is send a regular (weekly or monthly) spam report that tells your customers how many emails that were blocked vs the number of ham emails and other such statistics.
We quarantine mail that is between our target threshold and 10 points, above that we reject at the SMTP level. The quarantine report is sent daily.
This approach works well for two reasons, #1 is definitely marketing, #2 is that it makes users feel like our spam filter isn't blocking anything they wanted.
Sure, if we did quarantine something a user wanted, they might want to release it. Last I looked, there's a single digit number of quarantine releases per month, despite the fact that it's a single un-authenticated click from the email in their mailbox.
I do really believe that it makes users feel happier about the handful of spam that does make it into their mailbox when they see even a percentage of the stuff that didn't make it -- And it's a small percentage, a vast majority is rejected outright.
(Also, take my numbers with a grain of salt, my spam filtering system is comprised of more than just SpamAssassin, SA's score is directly added to various other rules for the final decision)
