Post Tag Assign
Applies a tag based on the contact’s Post Code by cross referencing the Post Codes area (AB1) against the tag names within the supplied tag category id. If tag cannot be found then a new tag is created and applied.
This makes it really easy to manage leads and contacts within a franchise or area specific environment. It also allows for a Default HQ Tag, in case someone enters a postcode not accounted for, as you would have when an area has not been sold yet.
