How to modify custom field personalization during delivery?

We have three modifier commands (as of Oempro v4.14.4) that you can use to modify custom field values during personalization:

Let’s assume you have a global custom field called “FIRST_NAME”. You can modify the values of this custom field in your emails using the following format:



  • [TITLE:%Subscriber:FIRST_NAME%]
  • [UPPER:%Subscriber:FIRST_NAME%]
  • [LOWER:%Subscriber:FIRST_NAME%]

If the value of FIRST_NAME global custom field is “John” for a subscriber, corresponding results for each one of these modifiers will be;

  • John
  • JOHN
  • john
