Copy & Paste only the Email address in OS X Mail

by

When copying an email address from OS X Mail application and paste it somewhere in Mac OS X, you get the contacts fullname as well as their email address (“Tim Cook ”). If you only want the e-mail address (t.cook@apple.com) to be copied use the following command: 

defaults write com.apple.mail AddressesIncludeNameOnPasteboard -bool false

Relaunch Mail application for changes to take effect.

Restore default copy behavior with:

defaults write com.apple.mail AddressesIncludeNameOnPasteboard -bool true
