Tired of the Apple Mail Client Woosh sound on mail send

I am using Macbook pro 13inch 2015 model. Using OSX Sierra.

Every time I send a mail with the apple mail client is makes a woosh sound. In order to suppress this sound I have done the following things

  1. Go into settings -> notifications and switch off the notification sounds for mail client.

  1. Disable User Interface sound effects in settings -> sound.

checkbox.
