Hi @curtds,
I am sorry to hear that your site experienced some trouble with setting up WP Mail SMTP with Sendinblue and Elementor Pro.
The Sendinblue mailer is available and does work with WP Mail SMTP, along with Elementor Pro. There may have been a configuration error or an issue that needs some troubleshooting.
The first thing I would recommend is making sure all the steps have been followed in our guide for setting up WP Mail SMTP with Sendinblue.
If you would like some help to get this fully set up, please create a new thread with the details in our support threads.
We’d be happy to get this resolved for you!
