Use your real email signature: Just like using a real reply-to email address, you want to use real contact information within the email and the best way to do that is to include your contact details in the email signature. Giving your readers the opportunity to contact you or connect with you online is a great way to be personal and build a relationship with them.
Head back to your Gmail window. Now, compose a message that you might use frequently, like “Thanks very much for this! I’ll get back to you as soon as I can.” To set up a canned response, click on the dropdown arrow in the lower right-hand corner of the Compose window, and choose Canned responses, followed by New canned response. You’ll have to name the response and save it to make it available.
