I'm running a spring cleanup of data, one of them is finding the right county for leads who have an empty country. Logically I would like to do this by email extension (.uk .nl .de). Only, this option isn't offered by Marketo. Too bad!
The 'contains' option is not sufficient. For example .ar (argentina) also includes all .army leads.
If anyone has a good idea, please share! Marketo, please add 'ends with' for the email adress filter.
