# Define Restricted Words

Define a list of words that, when detected in Distributed Marketing rich or plain text areas, automatically disable sending through Distributed Marketing. You can define specific words to restrict, and you can use standard regular expressions to prevent business users from sending information that’s deemed sensitive, such as account numbers.

Keep these considerations in mind when defining restricted words:

- Words must be alphanumeric characters. Punctuation and special characters aren't supported.
- Separate words by new lines, commas, or spaces.
- Words are case insensitive.
- The word limit is approximately 900,000 words, or about 6 million characters, including the delimiters in the .csv file.

- **[Enter Restricted Words or Regular Expressions Manually](https://help.salesforce.com/s/articleView?id=mktg.mc_dm_enter_rest_words.htm&release=264.0.0&type=5)**
