how do I actually use this? I downloaded it but am not sure what to do now? Do I just wait until there's an email that's supported by powerinbox? I use rapportive and boomerang, so I expected to see some kind of button within Gmail and I don't.
Thank you for reaching out. Since PowerInbox works on supported emails, you should see interactive content on the next email you receive from Facebook, Groupon, Twitter and more http://powerinbox.com/apps.
