Preventing duplicate contacts in mailchimp.

Mailchimp has auto-duplicate checking / merging for all the contacts you upload to their program. If you accidentally upload duplicate contacts to Mailchimp their auto detection filters will merge everything into a single unified contact record. This ensures you don't accidentally add the multiple copies of the same contact in their system.
