HOW WE VERIFY EVERY LEAD

The Answer to B2B Outbound. 85% of noise filtered out.

No off-the-shelf list dumps and no black-box magic. We combine proprietary extraction tools with hands-on GTM strategy—customizing our search logic, filters, and verification engine around your exact offer and ideal buyer.

STEP 01

1. Source Target Companies

We pull matching US businesses in your niche via location-based crawling, B2B directories, or start from your existing CRM seed list.

2. Extract Buying Signals

Depending on your chosen blueprint, we capture verbatim 1–2★ customer complaints, website/ad funnel gaps, or verified specialty tags.

100% Verbatim Public Proof
STEP 03

3. Match the Active Owner

We cross-check leadership pages and public web records to isolate the current Founder, Owner, or CEO—filtering out former staff and info@ inboxes.

COMMON QUESTIONS

Five Quick Answers Before You Test Us.

Have a custom territory or niche question? Request your free 5-row sample above or email hello@42leads.com.

1. How do you guarantee 0% AI hallucinations in review quotes?

Every pain quote is verified character-for-character against the original public Google or software review. If an AI model paraphrases or invents a single word, the row is automatically rejected.

2. Where does the data come from, and do you include info@ emails?

We never resell stale Apollo or ZoomInfo lists—every run combines fresh review extraction, website/ad-pixel crawls, corporate SERP checks, and a live SMTP ping. Generic role inboxes (info@, office@, sales@) are strictly excluded from your primary quota.

3. Are leads resold to dozens of agencies at the same time?

No—unlike public databases where 500 reps blast the same export on the same day, every batch includes a 90-day territory lock for your vertical plus permanent deduplication so you never pay twice for the same company.

4. Is this compliant with US CAN-SPAM, CCPA, and GDPR?

Yes. We process strictly public corporate web records and public reviews under US CAN-SPAM/CCPA frameworks, Singapore PDPA business-contact rules, and GDPR Art. 6(1)(f) with our Data Processing Addendum (DPA).

5. How are batches delivered, and what if an email bounces?

Your free 5-row custom sample and all ongoing monthly or bi-weekly batches are delivered as clean, ready-to-import CSVs or single-tenant Google Sheets. Any hard bounce above our <2% guarantee is replaced 1-for-1 in your next batch.

6. You reached out from a secondary domain—why did it redirect to 42leads.com?

Just like top US outbound agencies, we isolate cold email traffic on dedicated secondary domains (with strict SPF, DKIM, and DMARC authentication) that 301-redirect here to protect our primary corporate workspace—practicing the exact same sender-reputation discipline our <2% bounce data is built to protect for you.
