This question has been asked before, but I would like to cast the net a bit wider. Responses included using the Geo-eventProcessor to catch changes in the underlying feature services. It feels a bit like using a canon to kill a fly.
I'm not sure if Survey123 forum is the right place to address this (Ideas also has a couple of entries on this topic), but I would like to see integration of feature services with ITTT or Microsoft Flows as it would allow integration of Survey123 with many more applications.
The solution we have been working on for the City is exactly that; a script that will query the feature layer for a specific field that is indicative of a new record (time/date/status ect) compile that query into a list or table and send an email to the people responsible for it. What we have probably isn't very elegant, and we haven't run it fully, but it is one solution.
I wandered down this path from stories and word of mouth from other people using python script to achieve the notifications they wanted.
