SaneSubject Filtering: Trainings based on Subject Content

If an email subject line contains (or begins with, or ends with) a specific term you designate, we can filter that email into a select Sane folder destination.

To use SaneBox Subject Line Filtering: visit this page, available from your site Menu under Settings for Subject Filters.

Note: Subject filters can also be created now from in your Digest summary, right from the “Train To/Move To” button for a selection. (See an example on this help page here.)

How to use SaneSubject filters

  1. Choose whether the subject line you’re training for either “Begins With”, “Contains”, or “Ends With” a certain Term or Phrase that you’ll enter.

  2. Type in the exact word or phrase. Be aware that our system is not case-sensitive.

  3. Select the destination Sane folder you’d like to Create the @SaneSubject Training for.

Why can’t I use regular expression type entries?

As a precaution we don’t allow regular expression in the subject filter user interface, (extra risk factors covered here:, for fear that people might set up overly ambitious expressions that would redirect all their email to a single folder.

Please contact support if you want a manual regular expression subject filter applied to your account, by one of our engineers.


Each of your SaneSubject entries will appear in a listing as a line-item, and can be removed at any time. Also, your keywords will not be case sensitive.
