Data Enrichment

Data enrichment (also called data appending or data enhancement) is the process of taking your existing database records — typically contacts or companies — and supplementing them with additional data points from third-party sources.

For example, if you have a list of email addresses, data enrichment can add job titles, company names, phone numbers, social profiles, company revenue, employee count, and technology stack information to each record.

Common types of data enrichment include:

• Contact enrichment — adding personal details like job title, phone number, LinkedIn URL, and verified email to a contact record
• Company enrichment — appending firmographic data like industry, revenue, employee count, funding, and tech stack
• Intent enrichment — layering buying signals and behavioral data onto existing records

For sales and marketing teams, enriched data means higher email deliverability, more personalized outreach, better lead scoring, and fewer wasted touches on bad-fit prospects. Teams using enriched data typically see 2-3x higher response rates compared to outreach based on raw, unverified contact lists.
