How to Add Contacts to Brevo Mailing Lists

Brevo (formerly Sendinblue) is a free email and text message marketing service for creating email and SMS marketing campaigns as well as sending transactional emails.

To set up the import of emails and phone numbers collected through your website's forms into Brevo mailing lists, you need to enter the API key of your Brevo account on Tilda.
Sign in to Brevo and click on the name of your profile in the top right corner of the screen, then select SMTP & API.
Copy the API key (version v3).
On Tilda, go to the Site Settings → Forms → Brevo.
Paste the API key in the field and click on Add.
Select a list from those created on Brevo. If you want to use a new list, go to Brevo and create one before proceeding.

If you want to send data to multiple lists, please connect Brevo to your project several times—one setup for each list.
Save the changes.

You can assign the service to all forms on your website be clicking on "Assign the service to all forms on the website."
Go to the page with the form, open the Content panel of the block containing the form, select the "BREVO" checkbox, click "Save and close", and re-publish the page.
