Plivo Followup.ccI would recommend this to someone looking for a way to automate outbound calls. You don't need a developer, Plivo does all the heavy lifting for you. I use it for all my marketing needs and it has made my life so much easier. I have used it for a couple of years now, and I am always pleased with the quality of service and support.
Followup.cc might be a bit more popular than Plivo. We know about 1 link to it since March 2021 and only 1 link to Plivo. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
This is so nostalgic. I actually met my cofounder on github due to a discussion on twisted vs gevent back in 2011. I had my inital code in twisted and he wrote the gevent piece. Fast forward 12 years and we still use gevent at http://plivo.com :) Some of our initial code snippets: # Twisted. - Source: Hacker News / 9 months ago
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
