How Verified Business Lists Improve Lead Quality and Conversion Rates

Lead quality starts with accurate targeting. Verified, industry-specific lists built on SIC and NAICS codes reach the right companies, reduce waste, and lift conversion across email, SDR, paid, and direct mail.

Why verified lists outperform generic data

Precision ICP fit
Use the SIC Code Lookup and NAICS Code Lookup to define the exact industries you serve.

Higher contactability
Clean, validated records increase deliverability and reply potential.

Consistent cohorts
Standard codes make testing and reporting by industry reliable.

When you know the right codes, assemble your audience and source a verified, industry-specific list via the appropriate service pages (SIC or NAICS) before launching campaigns.

A simple playbook to lift conversions

Choose 3–8 priority codes. Start with industries where your win rate is strongest; add a few adjacencies for learning.
Segment by code + geo + size. Keep cohorts similar in volume for apples-to-apples tests.
Tailor messaging by industry pain. Use sector-specific benefits and proofs in subject lines and first sentences.
Normalize in the CRM. Store the code on every record and route replies/opps back to the cohort.
Scale winners. Expand budgets and add adjacent codes once lift is consistent for 2–3 cycles.
