Lead Enrichment Services to Complete and Update B2B Data
Transform incomplete leads into complete profiles. Append missing phone numbers, email addresses, company details, and demographics—so you can reach more prospects through more channels.
What is Lead Enrichment?
Lead enrichment (also called data enrichment or data append) is the process of enhancing your existing lead records with additional, valuable information. Instead of working with incomplete data, enrichment fills in the gaps to give you a complete picture of each prospect.
Think of it this way: You have a lead with just an email address. After enrichment, you might also have:
- Their mobile phone number (so you can call them)
- Their company name and size (so you can qualify them)
- Their job title (so you can personalize outreach)
- Their mailing address (for direct mail campaigns)
- Demographic data (for better segmentation)
The result? More ways to reach each lead, better personalization, and higher conversion rates.

Lead Enrichment FAQs
What is lead enrichment?
Lead enrichment is the process of enhancing your existing contact records with additional data points. This includes appending missing phone numbers, email addresses, company information, demographics, and other valuable data to make your leads more actionable.
What data can you append to my leads?
We can append: phone numbers (mobile and landline), email addresses, company name and size, job title and department, mailing address, demographics (age, income, homeowner status), and firmographics (industry, revenue, employee count).
How does lead enrichment improve my campaigns?
Enriched leads give you more ways to reach prospects (multiple contact points), better personalization (know their role, company, interests), and improved targeting (segment by demographics or firmographics). This leads to higher response rates and conversions.
What's the match rate for enrichment?
Match rates vary by data type and lead quality. Phone number appends typically achieve 40-60% match rates, email appends 30-50%, and company data 50-70%. We provide match rate estimates before you commit.
Do you verify enriched data?
Yes, all appended phone numbers are validated for connectivity and line type. Email addresses are verified for deliverability. We only append data that meets our quality standards.
How long does enrichment take?
Most enrichment jobs complete within minutes to hours depending on volume and data types requested. Large files (100,000+) may take a few hours. You'll receive real-time progress updates.
What file formats do you accept?
We accept CSV and Excel files (XLS, XLSX). Your file should include at least one identifier (name, email, phone, or address) that we can use to match against our data sources.
Limitations: When Lead Enrichment Is Not a Fit
Lead enrichment enhances existing data, but it has specific constraints:
- ✕Does not create new leads — Enrichment appends data to existing records; it doesn't generate new contacts.
- ✕Requires at least one identifier — We need a name, email, phone, or address to match against our databases.
- ✕Match rates vary by data quality — Incomplete or outdated input data results in lower match rates (typically 40-70%).
- ✕Not 100% coverage — Some contacts cannot be enriched if they're not in our data sources.
- ✕Data freshness limitations — Appended data reflects our most recent sources; job titles and companies may have changed.
Best for: Sales and marketing teams with existing CRM data who want to add missing contact points, improve personalization, and increase multi-channel reach.
