Will Alfred "New Reply Detected" trigger find a new replies for old leads?

Great question, @Morsy97!

I checked the internal notes here but couldn’t see anything to confirm whether the Alfred app would consider a reply in both new and old threads as “new”.

I’d have thought that it would trigger for new replies within old threads too, but I’m not 100% sure on that. I think your best bet here would be to finish setting up the Zap, turn it on and reply in an old thread to see if that triggers the Zap. 

If you do give that a try please let us know whether it does indeed trigger for new replies on old threads. Very interested to know whether it does or not!
