Data Append
Adding specific fields to existing records by matching them against a reference dataset.
Definition
Data append is the practice of attaching new data fields to records you already have by matching on a known key, such as appending phone numbers to a list of emails or adding company data to a list of contacts. It's a building block of enrichment. Reverse append is a specific case where the input is one contact field (an email or phone) and the output is the linked person and their other details.
Put data append to work.
