Pages document How to send via a different email address
I use Pages on my Mac for a lot of business letters but when I click the share button - Send a copy - I only get the choice of Mail, Messages or Airdrop. how do I get Gmail as an option. I have managed to change this setting on my iPad but cannot see how to change it on the Mac. I want to have the choice of sending from the Mail App and G.Mail. Any advise.
