How VeriMails Solves This

Verify before CRM import

Run every new lead batch through VeriMails before importing to your CRM. Remove invalid addresses, flag risky ones, and ensure your pipeline contains only verifiable contacts from day one.

API integration in lead capture

Connect VeriMails API to your lead capture forms, enrichment pipelines, or data import workflows. Verify in real-time as leads enter your system, preventing bad data from ever reaching your team.

Catch-all scoring for B2B leads

When targeting enterprise accounts with catch-all domains, VeriMails probability scoring tells you which addresses are likely real and which are probably fabricated. Prioritize high-confidence leads for outreach.

Bulk re-verification for aging leads

Leads sitting in your CRM for months may have changed jobs or addresses. Regular bulk verification keeps your pipeline current and prevents wasted outreach on stale contacts.

Recommended Workflow

1. Collect leads from any source (scrapers, databases, enrichment tools). 2. Before CRM import, verify via bulk CSV or API. 3. Remove invalid and disposable addresses. 4. Segment catch-all results by probability score. 5. Import only verified leads to CRM. 6. Re-verify leads older than 60 days before outreach. 7. Monitor bounce rates and re-verify if above 2%.

Pricing for Lead Generation

Lead gen teams typically process 5,000-30,000 new leads monthly. Pro plan ($29/mo) handles standard volumes. Business plan ($79/mo) is ideal for teams with multiple lead sources and frequent batch imports. API verification for real-time capture adds minimal overhead.

Frequently Asked Questions

Should I verify leads from Apollo, Clearbit, or ZoomInfo?

Yes. Enrichment tools provide contact data but don't guarantee real-time deliverability. Emails can be outdated, formatted incorrectly, or no longer active. Verify every lead before adding it to your outreach pipeline.

How does verification fit into my existing lead gen stack?

VeriMails integrates via REST API or bulk CSV upload. Verify after enrichment but before CRM import. Most teams add a verification step to their data pipeline, catching bad leads before they consume resources.

What percentage of leads should I expect to be invalid?

Purchased lists: 15-35% invalid. Scraped data: 20-40% invalid. Enrichment tool output: 5-15% invalid. Even the best sources benefit from verification. VeriMails' catch-all scoring additionally recovers leads other verifiers mark as unknown.

Is it worth verifying every lead?

At $0.0029 per verification, the cost of verifying a lead is negligible compared to the cost of an SDR spending time on an unreachable contact. A single wasted outreach sequence costs more than verifying 100 leads.

Can I automate verification in my pipeline?

Yes. VeriMails' API supports real-time verification. Connect it to your lead capture forms, enrichment webhooks, or CRM import workflows using direct API integration or automation tools.

Email Verification for Lead Generation

Every unverified lead in your pipeline is a gamble. Bad email addresses waste sales time, inflate CRM costs, and damage outreach deliverability. Verification at the point of capture ensures your team works only with real, reachable contacts.

The Challenges

Purchased and scraped lists have high invalidity

Third-party lead lists, database exports, and scraped contact data typically have 15-35% invalid email addresses. Feeding these directly into your CRM and outreach tools wastes resources and creates deliverability risks.

Bad data cascades through your funnel

An invalid email doesn't just bounce — it wastes your SDR's time on research and personalization, inflates your CRM costs, skews pipeline metrics, and potentially damages sending domain reputation if outreach is automated.

Enrichment tools aren't verification tools

Services like Clearbit, Apollo, and ZoomInfo provide email addresses, but they don't verify deliverability in real-time. An enriched lead with an unverifiable email is still a liability.

Catch-all domains hide lead quality

Many B2B companies use catch-all email configurations. Without scoring, your team can't distinguish between a real decision-maker's address and a fabricated contact on the same domain.
