want to sync real volve with Constant Contact

Hello, this is  assistant. He is requesting to start new email campaigns accordingly. We have different types of clients and will like to sync only those clients that we have an email on record in our main data base which is Real Volve. Wondering if it is Zapier we should work with or you might have another way to do this.

Looking forward meeting with you if possible this week. Let me know if anytime between 10am-4pm CST works fine for you.
Thank you!
