I agree that an option for "advanced tag management" is needed and would be of greatest benefit to CC users with extremely large contact lists.   What if the ATM screen had options for the following: toggle to include/exclude x AND y when  condition z = false toggle for include/exclude x when condition z = true toggle for include/exclude all except x when condition z = true/false ( z should allow for a specification of a numeric value for total # of tags AND/OR  selection of specifically names tags) stop processing criteria checkbox (to identify the last logic to be used to create current send to list) priority ranking to designate the order the criteria should be considered a timing field for resends that can be set for criteria that should run on a resend - i.e. resend 2 wks after original send date should use criteria # n (so those that responded or paid don't get a reminder 2 wks after the original send) way to flag all settings on the page and save it as a set of "favorite" or custom criteria (that can get a meaningful name by the CC user)...i.e. ALL except platinum - 1st send , or ALL except platinum - 2nd send , or ALL except platinum without responses , or ALL except platinum with responses , etc. This would be a huge timesaver when considering advanced logic arguments - especially if the favorite could be copied, given a new name, and tweaked rather than starting over from scratch when creating similar ATM logic arguments with slightly different criteria. I don't know what programming language CC uses, but I picture this feature working like a user friendly SQL query to fine tune contact selection. ... View more
