If you’re just getting started with Google Plus, you may not realize that you don’t need to open your page to post or comment. Gmail’s integration makes the Google Plus experience extremely easy and convenient.
One of the best ways to stay up to date with your Google Plus activity is through the notifications icon at the top right of your inbox. One of our favorite features is the ability to +1, post or reply to comments from the notifications icon.
If you choose to receive your Google Plus notifications via email, you can reply just like you would any other email. Just another example of great cross-platform integration with Google Plus!
