This one is a no brainer. I first tried this a few years ago after reading an article about Rebump on, IIRC, Techcrunch. I tried it and quite liked it BUT there was a rendering issue in my compose window in Gmail. At the time I had quite a few gmail extensions and because of this issue I let Rebump go. However since it came to AppSumo I figured I'd give it another try. Great call.

That rendering issue has gone away and Rebump is playing nice with all my other email extensions. So why would you want it? Simple. It allows you send your own personalised email, as you normally would compose it in Gmail, and attach a follow up sequence - all fully customisable - so your target gets prompted to pay attention to your email.

This is such a small thing but it makes a big difference in practice. Since reinstalling Rebump I'm seeing and benefiting from tangible results but the biggest benefit to me is the feeling I get once an email is sent, I now know I'm fully locked and loaded and that my follow up is fully baked in right from the start. It's a blissful liberation from setting myself reminders to follow up. This is not for later, this is for right now. Deploying this is a matter of only a few minutes work and after that it does the work, not you.
