100 leads/contacts per page - REALLY?

100 leads/contacts per page - REALLY?

Is there a way that I can checkmark leads from different pages and send them an email? Basically, it would be creating a mailing list by selecting specific leads.
 
It is VERY FRUSTRATING that I am supposed to create a new "View" every time I want to contact specific leads. Most of the time it is IMPOSSIBLE to even create a "View" that works for us.

Grateful for any good tips!
