Hi @bookdrive.lokd
Welcome to the Auth0 Community!
I’ve checked your tenant configuration and it looks like the Mandrill is not enabled, please check if you configured it properly and the service is enabled.
Thanks

Yeah, that’s because I had changed back to default Auth0 web services so that my application keeps running but when I fill the API key and From email it shows this failed sending notification. So kindly help me with that. @dawid.matuszczyk
Hi @bookdrive.lokd
Sorry for the late response,
From what I’ve checked, the error 535 5.7.8 is an authentication error. Please check if you have inserted the proper API key generated in the Mandrill app.
Thanks
