Hi there, I have been trying to make identify contacts that have empty fields - for instance, contact with a missing city on their contact record. What would be my best bet? ---

The easiest way to search for contacts with empty fields is to go to Contacts \> Misc Criteria Tab \> Scroll down to “Data Exists” and there is an option to select from most of the standard fields and “Doesn’t have a value.” It doesn’t include custom fields, but you can go to the Custom Fields tab and choose a field and then select “Doesn’t include” and then in the field try an underscore " \_ " which is a wildcard. You can also run Legacy action sets with rules - but the way above may be your easiest bet especially for something like city. ---

Great - thanks for the answer Cheryl. Now what I was really trying to do is classify my contact per mini geographical zones within a main city. What I’ve done is create a campaign that apply a ‘zone tag’ to my contacts depending on their suburbs. I’ve broken down the city in 13 zones, each zones has about 10 suburbs. I’ve used a decision diamond to decide which tag to apply. Now the issue come when the contact’s “city” field is left blank or if the suburb hasn’t been entered correctly (typo) - I was hoping to create a 14th sequence that catches all those mistakes or blank field. Hope this makes sense? Any ideas? ---

I was very glad that you highlighted that “Data Exists” option. Now I walked in today and just figured that they finally have enabled the check for empty / filled field directly on the field when searching. I might have been blind, but I think this is fairly new… ---

It’s been in place for a while but it’s seldom talked about 😜 ---

right, I rememberd, I was actually desperately looking for this option in a decision diamond, unfortunately still not there…
