Unlimited and forever free tool to track your emails easily. This is SONAR, a Gmail tracker extension for Google Chrome that makes you able to track your email activities, such as when your email is opened. Other than that, SONAR will give you peace of mind and a hint of what next email you should send or the next action you should take after you send an email and know who opened your emails, and how many times your emails are opened.

I'll update this if I find more. For now, this seems to be a partial solution. It's a Gmail add on (except I don't use Gmail) that adds reminders. The options when setting reminders include cancelling it if someone replies, and to remind everyone in the thread. If you combine those two, it seems like — if you use Gmail's web client and have $23/month you're dying to get rid of — a decent way to add the feature. Source: over 1 year ago
