Group Email and Block contacts

Dhanavel. S

1. When sending group email, why pipedrive can't trigger once 100 contacts selected? it makes me to count 1 to 100. Simple feature to be added.
2. How to block / highlight / trigger some contacts as they dont to receive our follow up emails. Please suggest.
