Below you will find information about how duplicate email addresses are handled. By default, your account is setup with the email address being the unique key. This means that only one record will be created per one unique email address.
Through CSV import, there are two options for handling duplicate records:
a. Checked box for "Update existing contact records": the system will check to see if the email already exists. If it does, the system will check for new fields or changed information in existing fields and append that information to the existing record.
b. Unchecked box for "Update existing contact records": the system will check to see if the email already exists. If it does, the system will ignore it. Only email addresses that do not already exist in your account will be added through the import.
1. If you have a need for multiple records per email address you may need access to our Custom Tables feature. Custom Table availability is based on your license. Please contact your Client Success Manager for details.
2. Our campaigns and automation can support the use of a unique ID to control multiple records using the same email address. This means you can send multiple emails to the same email address or send the same email address through an automation multiple times. Requires a custom table.
