How many options we can list down when setting up an IF Contain Rule in Conditions?

Hi, We're just wondering what the limits are for the contains condition.

We're wanting to set up a referral program that allows current clients to share a friends & family discount... with their email acting as the discount code.

If we were to enter all our current client's emails into a "contains" condition field, all separated by a comma, we're just wondering how many emails or contain elements can be added to that contain field before the form starts to degrade or lock-up as a result of the "search" for a match amidst all the emails stored.

We would be starting with about 300-400 emails. This number would grow as we continue to add more emails to the field over time.

Thanks in advance!

Merry Christmas!

I tried this with 1 thousand emails and it's working. If you cannot add an email beyond this number, you can just add a new IF rule or condition. Here's an example:

Make sure to select "IF ANY" in the dropdown for triggering the logic.
