Kunal Bhatia- Co-founder & Design Lead @SlidesUpI love Boomerang. I use it mainly for their scheduled emailing and their "Respondable" feature, which tells you how likely your email is to get a response. Helps coach you write better emails.
John Ababseh- Epiphany EnthusiastI love boomerang an amazing tool for controlling emails sent and received.
Yoni Shechter- Founder at @FavorizeAppSuper simple add-on to Gmail, which I mainly use to return an email back to my inbox in X days so I can act on it. Also useful to send an email later at a specific time and date, and return to inbox if no reply from email recipient. While I wish Gmail just had it for free, I love it and gladly pay $4.99/month to make sure I'm organized and on top of things.
