Google really wants you to use Gmail to call your dad to wish him a Happy Father’s Day. On the front page of Google search (which features a Dad-themed Doodle), Google has a message underneath the search box “Dad. Father. Pops. No matter what you call him, call your dad from Gmail.”

If you click on the message, you are taken to a page that shows you how you can call your Dad for free (in the U.S. and Canada) from Gmail. Google has even added a note in your Gmail chat roster, right under the “Call phone” link, to remind users to call their Dad.

Google launched Gmail Calling last August as a simple way for email client users to make free calls within their browser. Dialing a phone number works just like a normal phone. Just click “Call phone” at the top of your chat list and dial a number or enter a contact’s name. And the quality is pretty good and calls are free thanks to Google extending the offer of free calls in the U.S. and Canada through December.

While Google did create a special Doodle and tribute page for Mother’s Day this year, it did not promote one of Google’s products.
