By Impran M N
Growing a subscriber list or collecting customer data doesn't require writing custom HTML from scratch. Brevo's drag-and-drop form builder handles the design and compliance details, including double opt-in confirmation, so you can embed a working sign-up form on your website quickly.
01Create a new form container
From the main dashboard navigation, create and name a new internal subscription form to start building.
02Design the visual elements
Use the left-side sidebar to add and personalize fields, font themes, and layout elements for the form.
03Map custom profile attributes
Connect each form field to the corresponding custom attribute in your contacts database so submissions populate the correct data.
04Set up double opt-in
Enable the dual confirmation loop so new subscribers must confirm their email before being fully added to your list.
05Grab the embed snippet
Copy the responsive iframe embed code and add it to your website where you want the form to appear.
