Should I Add Birthdays to Profiles in A Welcome Flow through a Preference Page or Signup Form?

Hi @Veilig, 

Welcome to the Community! This is a great question to ask, as it’s best practice to to collect information from your subscribers to give them the most personalized experience possible! 

While you are correct, a Date Property  isn’t an up-front option to insert in the ‘Manage Preferences’ Page, there is still a way to Collect Customer's Birthdays through a Preference Page! It is imperative for any date data type to be formatted in a certain way to be recognized in Klaviyo. To update your Preference Page to collect birthdays, I suggest adding a ‘Text Field’ that would supply the necessary format needed for Klaviyo to recognize the birthday data correctly, included pre-filled text to ensure the information is inputted correctly by your subscribers, as seen below. The Property will need to be formatted MM/DD/YYYY to be recognized successfully. Don’t forget to Save the Field when you’re done! 

I would also suggest checking out these Community Posts to gain further insight form fellow users asking the same question! 

Thanks for being a part of the Community!
