Lead Enrichment FAQ: Data Append Services Explained
Lead enrichment is the process of appending additional data—like phone numbers, emails, demographics, and firmographics—to your existing contact records. Here are answers to common questions.
What is lead enrichment?
Lead enrichment is the process of appending additional data to existing contact records. This includes adding missing phone numbers, email addresses, demographics, firmographics, and social profiles to incomplete leads.
What data can be appended to leads?
Common enrichment fields include: phone numbers (mobile/landline), email addresses, mailing addresses, age, income, job title, company name, industry, company size, revenue, social media profiles, and online advertising IDs.
What is a match rate?
Match rate is the percentage of records in your file that we can find additional data for. A 70% match rate means we found enrichment data for 70 out of every 100 records. Match rates depend on your input data quality.
How accurate is appended data?
Accuracy varies by data type. Email accuracy is typically 95%+, phone numbers 90%+, and demographic data 85%+. We verify data against multiple sources and flag confidence levels so you know what to trust.
What's the difference between B2B and B2C enrichment?
B2C enrichment adds consumer data like home address, age, and interests. B2B enrichment adds business data like work email, job title, company firmographics, and professional social profiles. We offer both.
What identifiers do I need for enrichment?
You need at least one identifier: name, email, phone, or address. The more identifiers you provide, the higher your match rate. Name + ZIP code, or email alone, typically give the best results.
How fresh is the enrichment data?
Our data sources are updated continuously, with most records refreshed within the last 90 days. We timestamp appended fields so you know when the data was last verified.
Can enrichment help with advertising match rates?
Yes. Our online audience append adds digital identifiers that dramatically improve match rates on Google, Meta, and LinkedIn—typically 3-5x higher than using just email or phone alone.
Is enriched data compliant with privacy laws?
Yes. All data is sourced from opt-in, publicly available, or permissioned sources. We comply with CCPA, GDPR (for applicable data), CAN-SPAM, and TCPA. DNC scrubbing is included.
How is enrichment different from buying new leads?
Enrichment enhances leads you already have. Buying leads gives you entirely new contacts. Enrichment maximizes the value of existing data, while new leads expand your reach to new prospects.
