It’s time to stop wasting time and credits on bad data. With Lusha list verification, every contact is enriched and validated before outreach—so your team gets higher deliverability, cleaner CRM records, and better response rates.

Sales teams spend time and budget building contact lists, only to find that half the emails bounce or the phone numbers don’t connect. Bad data doesn’t just waste credits—it slows reps down and hurts sender reputation. That’s why verifying lists before outreach is critical.

With Lusha, you can run list verification directly through the API, CSV uploads, or Sheets automations. This ensures every contact you send to your reps is enriched with verified data before they start outreach.

Why list verification is critical for RevOps and Sales

  • Protect your sender reputation: Reduce bounce rates and spam flags by verifying emails before sequences go out.
  • Save credits and time: Don’t waste enrichment credits on records that can’t be reached.
  • Keep CRMs clean: Verified data reduces duplicates and inaccurate records.
  • Boost productivity: Reps focus only on prospects with verified contact info.

How the workflow works

Workflow example:

  1. Upload your raw prospect list (CSV, CRM export, or marketing campaign leads).

  2. Use the Lusha API or CSV enrichment to validate emails, phone numbers, and job titles.

  3. Return enriched and verified contacts to your CRM, Sheets, or campaign platform.

  4. Flag or remove contacts that don’t pass verification.

  5. Push the clean list into Outreach, Salesloft, or your email tool for sequencing.

Result: Higher deliverability, cleaner data, and fewer wasted outreach attempts.


Example automation: Google Sheets recipe

  • Trigger: New row added in Google Sheet with prospect name + company domain.
  • Action: Lusha API verifies and enriches with phone + email confidence score.
  • Action: Mark verified contacts as “ready for outreach.”
  • Optional: Auto-sync verified contacts into HubSpot or Salesforce campaigns.

KPIs to track

  • Email bounce rate % (should decrease after using Lusha verification).
  • Verified vs unverified contact ratio per list.
  • Outreach response rates before vs after verification.
  • CRM hygiene score (duplicate + stale record reduction).

Best practices for list verification

  • Run verification before every outbound campaign, not after.
  • Prioritize high-value lists (ABM accounts, event lists, strategic campaigns).
  • Use verification to clean old CRM records regularly.
  • Pair verification with segmentation to improve targeting and personalization.

FAQs

List verification is the process of checking your contact data for accuracy, validity, and deliverability. With Lusha, you can automatically enrich and verify email addresses and phone numbers before your team starts outreach.

Unverified lists lead to high bounce rates, poor deliverability, and wasted rep time. Verification ensures your team only works with accurate data that reaches the right people.

Yes. Lusha provides both enrichment and verification in one step. Instead of running data through multiple vendors, you can validate emails and phones as part of your enrichment flow.

By keeping invalid or duplicate records out of your CRM, you maintain cleaner data. This reduces manual cleanup, improves reporting accuracy, and ensures sales reps trust the system.

Absolutely. Every bounced email wastes credits, lowers deliverability, and risks spam flags. Verified lists mean fewer wasted sends and more ROI from each sequence.
