Finally, found this amazing plugin ??

I was really tired up, trying and using all methods to integrate my Elementor forms to Brevo (old name SendinBlue). All others methods were having limitations or costs. Finally found this plugin. Big thanks to the developrs.

So, if you’re looking for a way to connect your elementor form with Brevo, in such a way that someone fills the form and their data (name, email, etc.) automatically fetched in Brevo CRM, this plugin can do this magic. Do and use it.
