Hi ramnathk,
Thank you for reaching out!
My name is Valeria, I work as Product Manager at Sendinblue.
Even though you can send test emails, the actual transactional emails won’t be delivered to your customers.?
The reason is that test emails are sent directly through our API when sending transactional email calls “wp_mail()” function.
The notification you see displays when another installed plugin defines SMTP “wp_mail()” function.
So, when real mail is triggered, WordPress finds wp_mail function defined by another tool and sends the email accordingly, in this case, not using Sendonblue.
If you remove the other plugin, the notification will be turned off and transactional emails sent using Sendinblue plugin.
Thank you for raising this issue, we will work on communicating SMTP settings during plugin setup process.?Also, we would appreciate your feedback about the notification itself. Was it helpful for you?
??If you have any further issues, don’t hesitate to contact me directly ([email protected]) or [email protected] for further investigation. ??
Have a great weekend!
All the best,
Valeria
