When you use Apollo for prospecting, it's possible that you will get duplicate contact information when you sync Apollo to your Customer Relationship Management (CRM) platform. Apollo automatically notifies you if there is a probable duplicate, which allows you to merge the duplicates and clean up your contact list.

Can't Win Them All

Please note, despite our best efforts, Apollo will never be entirely duplicate free. Apollo will always experience around a 1% duplication rate in our database.

See the sections below for instructions on how to merge duplicate accounts in Apollo and preserve your source of truth.
