Hi. 
When entering an email the option to classify it as Work, Home or Other, exists. 
Unfortunately, apparently there is no way to create lists of contacts with one of these types of emails. Is either all or none.  
I would like to be able to filter the contacts by "Work" email for instance so we could approach them with a different type of message that the one sent to those with a "Home" email address. 

It might also have some positive implications from a GDPR perspective as well... 

Hope this is not too difficult to implement. 

Regards,
