We’ve made it pretty easy for you to make Shift your default email client. This would result in Shift being used to open any link in your browser associated with an email function. An example of these functions would be mailto links.
To set this up, head into the Shift app:
Click “Settings” (wrench icon)
Go to “General”
Under “Functionality,” click ‘Set as Default’
Once selected, you should see a green circle with a checkmark. That means that your settings have been saved and Shift is now your default email client
