    Data Enhancement FAQs

    What is data enhancement?

    Data enhancement is the process of improving your or your client’s first-party data with context pulled from additional external sources. Also known as data append services, data enhancement services enable you to add various data points, such as contact, demographic, firmographic, or geographic information, depending on your marketing needs.

    Why is data enhancement important?

    Data enhancement enables you to quickly learn about customers and prospects, avoid wasting resources on the wrong people, strengthen your understanding of your customers, help you grow into new markets, and improve the customer experience.

    How does data enhancement work?

    Here’s how the data enhancement process works:

    1. Your team outlines your marketing goals, specifically noting what data assets will help you achieve them.
    2. You partner with a data provider (such as Deep Sync) to enhance your database.
    3. Your internal records are compared side by side with external datasets, aligning your records with the third-party data.
    4. Information is pulled from these third-party datasets to supplement your existing records and create a more comprehensive picture of your audience.

    What are data enhancement best practices?

    Data enhancement best practices include:

    • Auditing your database
    • Creating ongoing data hygiene procedures
    • Appending data with your marketing goals in mind
    • Validating any appended data
    • Working with a partner that specializes in data enhancement
