How Does Bedrock Dedupe Contact Objects?
For all of our Connectors, we use the standard Email Address field to dedupe contacts between different systems.
John Adams from Acme Corp is in your marketing automation system with the email address of email@example.com. He is also in your CRM system with the same email address. When these two records come down into the Bedrock sync, they will find each other and instead of new records being created in either system, the Bedrock integration will make sure to update the related records.
