In this article, we will explain how to pre-populate a form in a landing page with contact attributes. 

Pre-populating the fields in the form of your landing page will make things easier for your existing contacts as they won't have to fill them in manually.

Good to know

• The contact and their information are already stored in your Brevo contacts. If a contact or some of their information is not yet stored in your Brevo contacts, the corresponding fields in your form will appear blank.
• Your landing page is shared through an email campaign. This is the only way we can recognize your contact and get their information.
• You are using Text-type contact attributes, such as email or first name. You cannot use Number, Boolean, or Date type contact attributes.
