We've always supported the newsletter integration with Brevo, since the API connection was still working under the old name of Sendinblue. However, we understand that this might be confusing, especially for new users who are not aware that Brevo was previously Sendinblue.
To avoid any confusion, we've released a new standalone integration for Brevo, which you can find among the newsletter sync options.
Any newsletter user can now choose Brevo as their preferred service to automatically sync new subscribers from their linkinbio page to their Brevo lists.
If your newsletter software isn't yet part of our integrations, suggest it here.
