there's no way to see contacts or org's within a specified distance of a location.

When on a Contact/Organisation you can open the map, by pressing over the address, and check nearby hits Iwithin a specified distance. 


But it's not possible to do this with a filter 

let me try this

the only thing is how can i see a list of th ehits on the map and send them an email

you can't other than one by one. You also cant filter the results in any way, unless I'm missing something


It allows you to check other hits and individually email them but its not possible filter by Geolocation
