Email For The Lazy: Prewrite Gmail Messages With Canned Response
1. Click the gear icon in the upper right-hand corner of Gmail, then choose Settings.
2. Click the Labs tab, find Canned Responses, click the Enable radio button to enable Canned Responses, scroll down and click Save Changes.
3. Compose an email message you’d like to use over and over again, and then click the arrow in the lower right-hand corner of the message window. Choose Canned Responses, and under the Save heading, select New Canned Response. Give your response a name and click OK.
4. The next time someone emails you something that warrants the canned response you created, reply to the message and instead of typing your response, click the arrow button in the lower right-hand corner, select Canned Responses, and then under Insert, choose the canned response you created in the previous step. You’ll then see your response appear in the body of your reply.
