Multiple sign up forms - only display one during user session

Hi @clairebeaumont,

Welcome to the Community!

Any Behavior Settings in place for a specific Form only apply to that specific form. Klaviyo does not use "viewed Signup Form A" data as a determining factor in whether or not Signup Form B is shown to the same customer. Perhaps the examples below will help to clarify:
 

EXAMPLE 1:

• Signup Form A exists on URL A and Signup Form B exists on URL B
• Both Signup Forms have the following Behavior set: Don't show again after Submit Form or go to URL action
• Customer Submits Form A on URL A 
• Customer would still see Form B on URL B

EXAMPLE 2:

• Signup Form A exists on URL A and Signup Form A also exists on URL B
• Signup Form A has the following Behavior set: Don't show again after Submit Form or go to URL action
• Customer Submits Signup Form A on URL A 
• Customer would NOT see Signup Form A again on URL B

* Please note that the Behavior Setting "Don't show again after Submit Form or go to URL action" does NOT apply to clicking the "X" button to close the form or simply clicking out of the form.  

Hope this helps. 

Alex
