Mass Email and duplicate handling for duplicate contact records (will ZOHO recognize duplicates?)

Mass Email and duplicate handling for duplicate contact records (will ZOHO recognize duplicates?)

Our ZOHO CRM is set up for the cable television industry.

Typically the same district manager will manage about 20 locations for a cable system company.  There are about 10,000 cable systems in the United States. 

We need to have a unique record for each location as other types of contacts are linked to each unique location. 

Since we plan to sometimes Mass Email (250 a day max) to the cable system locations we are concerned that occasionally we might send a duplicate email to some district managers. 

Before we figure out a work around for the situation I have a simple question.  When we send out a Mass Email to a group of 100 contacts will ZOHO CRM remove the duplicate emails before sending the email?  Or will ZOHO CRM send out the mass email to 100% of the contact records (even if they are duplicates)?

Thanks.  The answer will help us in figuring out how to handle these duplicate contacts.
