You can add an unlimited amount of properties to recipients using CSV or API.
Properties using CSV:
Add each property name as a column header when you’re uploading recipients, with the values underneath (matched with the recipients)
Within our application, we also provide a template you can use!
If you want to guarantee the order in which you can export your properties later, upload them in alphabetical order, since this is the order in which we return them
Properties using API:
Check out our documentation to get an explanation of adding properties via API.
Solutions to common questions:
Q – Why can’t I see my properties after I import them?
A – This is something we’re still working on! Right now when you import recipients, you’ll only see the email, first name and last name – but don’t worry, the properties are there as well.
