HubSpot email has gotten even more social. Now, along with Facebook, Twitter and Linkedin, HubSpot customers will see Google+, Pinterest and click-to-email in the social sharing section of the email tool. The social sharing module within email makes it easy to set up share buttons without having to hand-code each image. Just add the url that you want the buttons to share and then turn on the networks for which you'd like to enable sharing.
Google+: When an email recipient clicks the Google+ icon, a Google+ screen will open and give them the option of sharing the assigned link publicly or to one of their circles.
Pinterest: When adding the share on Pinterest option to your emails, users will be able to specify both a link to share and an image to display.
Click-to-email: Simply, click-to-email opens a new email window for the recipient of the email to forward the specified url.
