could we see your snippet? did you strip it down to the very basics and test it?Not sure which Snippet you're talking about. It's the default Snippet which comes with Notify
On the Snippet of Notify I've added custom properties to use a group for all recipients which works fine at all.
First, try installing QuickEmail and testing to see if it also sends two emails. Could we see your Notify snippet tag (on the Notify resource)?QuickEmail: I've checked QuickEmail with default properties and debug=1. Output seems to be OK and it sends a single email (not twice)
No, I've not changed a single character in the snippet code. The group I'm talking about is a property of the snippet.On the Snippet of Notify I've added custom properties to use a group for all recipients which works fine at all.It seems you have edited the snippet? What is this group function?
