Know this about Marketo adding multiple values in smart list filter

Marketo's smart list filter supports characters up to 50K in the input box in case you're adding multiple values to it for filtering people.

In most cases, if the characters in the input box exceed the allowed limits, the smart list filter won't save and will run into errors. Also, just to be super clear, 50K is the limit for the number of characters, not the number of distinct values for the filter.

If you have values that surpass this limit, then it's recommended to:

- Separate them using multiple filters in OR logic
- Use a broader smart list operator (starts with, contains, etc.) to reduce the number of distinct values in the SL filter
