FAQ
What is data enrichment and why do companies use it?
Data enrichment is the process of augmenting existing customer or prospect records with additional information sourced from external databases. Companies use it to fill gaps in their own data (e.g., adding missing email addresses, phone numbers, or demographic attributes), to enhance the depth of customer profiles for better segmentation and targeting, and to improve the accuracy of scoring models used in credit, fraud, or propensity analysis. Enrichment turns a minimal record — perhaps just a name and address — into a more complete profile that supports more sophisticated marketing, sales, and operational decisions.
What is data rental and how does it differ from buying a contact list?
Data rental means accessing a curated list of contacts for a specific, one-time campaign use — typically a direct mail or email send — without receiving or retaining the underlying data. The contacts never enter the renter’s database; the campaign is executed by the data owner (or a trusted intermediary) on the renter’s behalf. Buying a contact list, by contrast, transfers ownership of the data to the purchaser for ongoing use. Data rental is often preferred for GDPR compliance reasons, since it avoids the legal obligations that come with storing personal data, while still allowing a company to reach a targeted audience it couldn’t otherwise access.
How can a company reach new customers who are not yet in its database?
eaching audiences beyond an existing customer base typically involves one of three approaches: paid advertising (targeting based on platform data), partnership marketing (co-marketing with complementary brands), or data solutions (renting access to a curated external list that matches a target profile). Data rental through a provider like DQE’s Rekkolt solution allows a company to define a target audience by socio-demographic or behavioural criteria, and reach them via direct mail or email without acquiring the underlying personal data — making it a GDPR-compatible prospecting channel.
What criteria can be used to select a data rental audience?
Data rental audiences are typically selectable by a combination of geographic criteria (region, department, postal code, catchment area around a store), socio-demographic criteria (age range, household composition, income bracket, homeowner vs. renter), and behavioural criteria (purchase history in a category, channel preferences, lifestyle indicators). The more granular the selection criteria available, the more precisely a company can target its prospecting campaign and avoid wasting budget on contacts unlikely to respond.
How does data enrichment support lead scoring and sales prioritization?
Lead scoring models assign a probability-to-convert score to each prospect or lead, based on their characteristics and behaviours. The more complete and accurate the data feeding the model, the more reliable the scores. Enrichment improves lead scoring by filling missing fields (e.g., company size, industry, seniority for B2B; age, location, income proxy for B2C) that are strong predictors of conversion. Sales teams can then prioritize outreach to the highest-scoring leads, improving efficiency and conversion rates. Enrichment also helps identify which leads are worth investing time in before a salesperson makes first contact.
