CF7 Brevo Integration Adds Contacts But Never Sends the Welcome Email - Here Is Why

A site owner posted on the WordPress support forums with a problem that was driving them crazy. Their CF7 form was connected to Brevo using CF7's built-in integration. Contacts were being added to the Brevo list perfectly after every form submission. But the welcome email was never being sent. Brevo support confirmed they were receiving no email send request at all from the website.

The CF7 plugin author suggested deactivating all plugins and switching to the default theme. On a live production site, that is not a realistic option. The thread was left unresolved.

The real reason this happens has nothing to do with plugin conflicts. It is a gap in what CF7's built-in Brevo integration actually does.

What CF7's Built-In Brevo Integration Actually Does

CF7 added native Brevo integration as a built-in feature. When you configure it and a form is submitted, CF7 makes an API call to Brevo to add the contact to your selected list.
