I am needing to create a mailing list of people from Switzerland where postal code is less than or equal to 3000 (to target french speaking people in Switzerland)
My 'postal code' data is currently text based.
I have read from another Sanford Whiteman post (https://nation.marketo.com/message/188320-re-postal-code-range#comment-188320 ) that i should create a duplicate field 'postal code range' and make this field type 'Integer' - i have done this.
BUT, how can i
1) duplicate the current data from 'postal code' into 'postal code range'
2) ensure this continues to happen each time new 'postal code' data is added?
- we currently have NO CRM connection. Data is just held / imported into Marketo.
Many thanks for your guidance and helping a newbie.
