Using regular expressions to search or filter addresses

This help article is for an old version of Direct Mail.

Direct Mail supports using regular expressions in the following locations:

  • The "Find Addresses Matching Rules" window (via Edit > Find > Find Addresses Matching Rules in the menu bar). When creating your search rules, the "matches" operator interprets the text that you type in as a regular expression.
  • Smart groups. When creating your filtering rules, the "matches" operator interprets the text that you type in as a regular expression.
  • Autoresponder recipient filtering. When creating your filtering rules, the "matches" operator interprets the text that you type in as a regular expression.
  • Template section visibility rules. When creating your visibility rules, the "matches" operator interprets the text that you type in as a regular expression.

Syntax

Regular expressions in Direct Mail use the ICU Regular Expression syntax and are case-insensitive.

Regular expression patterns in Direct Mail are implicitly anchored to the start and end of the subject string. In other words, if you enter the following pattern:

friends?

…it is considered the equivalent of this pattern:

^friends?$
