My tip is to enable canned responses in Gmail.
Go to Gmail – > Settings -> Labs – > and “Enable Canned responses”
Then, every time you write an e-mail that 90% similar to something you type all the time, make it a canned response. I have about 6 of these for my most common responses to people. It has saved me not just time, but the associated willpower that we lose from frivolous or redundant tasks.
