Ringtone notification

[AC Question]

I have suddenly started having a crazy ring tone when I get an email and I've never had that before how do I stop it

Which phone?
Which version of android?
Which carrier?
Which email app?

In your email app, check the notification settings to see what sound you have selected to play.
If there is no specific sound for emails, check the phone settings for the generic notifications.
