I have relied heavily on the Mail function in database view to combine and dedupe tens of queries at once for comprehensive mailing lists. This function is not as reliable as it once was, and I have had to use merge queries (which only allows for two at once) to accomplish what I need. PLEASE give us a way to stack up multiple queries in NXT.
I'd like to add SEGMENT to the title of this idea so more people see it! The segmentation feature in Mail/Quick Letters is very valuable! It's so much easier than merging when you have more than 2 or 3 input queries. I am hopeful this will roll out with the Export feature, or can be added somehow!
