How to see birthday sign up rate analytics?

Hello @armedandgorgeous,

Welcome back to the Klaviyo Community!

When using a multi-step signup form, the form analytics would be indicative of just the first step in the form as mentioned in our Understanding sign-up form analytics Help Center article. 

Although we don’t have support to see analytics for the following steps in a multi-step sign-up form, you can manually calculate how the second step performs. To do this, you’ll want to include a hidden property on the submit button of the second step. This way, when users submit with that specific button, they would be tagged by the hidden property. 

In turn, you can use segmentation to capture and count the number of subscriber who have this specific hidden property and consent between a specific date. You’ll have to use some assumptions here to gather the form view rate from the normal form analytics. But this should offer you a good idea of how well the second step of the form is performing. 

I hope this helps!
