I want to send an SMS to a specific list of people that updates every day. The list is the output of a SQL query and is stored in a data extension. I've looked at using an Import Definition in MobileConnect to transfer people from the DE into a mobileconnect list. The issue with this is that it only lets me add or update the list, not overwrite it.
Has anyone done something similar? Am I going about things in the wrong way?
Thanks
