Cleaning & Verification

TL;DR

Before you send anything, make sure the person is real and the email is deliverable. Verify contacts and emails with a third-party tool (e.g., LeadMagic, NeverBounce, ZeroBounce). This protects your domain reputation, reduces bounces, and keeps you out of spam folders—while ensuring the message reaches the right person.

Why this matters

Relevance: Data vendors and reverse-IP tools aren't perfect. Titles change, people leave, and "likely visitors" are sometimes just coworkers. Verifying prevents you from pitching the wrong person.

Deliverability: High bounce rates tank your sender reputation. Once your domain is flagged, even good emails land in spam.

What to verify (plain English)

Identity: Is this the right human for your ICP? (title, department, seniority).

Email health: Does the mailbox actually exist? Is it a catch-all, disposable, role account (info@), or risky?

Fit: Does this person still work at the company and influence the problem you solve?

A simple, reliable workflow

1. Start with clues -From Vector/rB2B/LeadForensics, match the visiting company → identify likely personas (Sales Nav search).

2. Pull the best-fit contacts -From Apollo/ZoomInfo/Sales Nav.

3. Verify emails -Run through LeadMagic (or NeverBounce/ZeroBounce). Keep only "Valid/Accept-All (tolerated)" per your risk level.

4. De-dupe & normalize -Merge duplicates, standardize fields (company, domain, title, country).

5. Send small → scale -Warm your domain, start with low daily volume, monitor bounce/spam/opens, then ramp.

Tools that make this easy

Verification: LeadMagic, NeverBounce, ZeroBounce, Bouncer.

Enrichment/backup: Apollo, ZoomInfo, Clearbit.

Org validation: LinkedIn & Sales Navigator (confirm title + tenure).

Rules of thumb

-Keep total bounce rate < 2% (per campaign and overall). -Avoid role accounts (info@, sales@) and obvious traps. -Verify before every major send (data decays fast—assume 3–5% monthly). -Tag your source (source=apollo / source=vector) so you can see which providers produce the most deliverable records.

Common gotchas

Catch-all domains: Decide your policy upfront (some teams allow them for high-fit targets, others don't).

Stale titles: Always re-check on LinkedIn; people move every few months.

Over-sending new domains: Warm first (gradual send volume), or you'll ruin deliverability.

Minimum data standard (before you send)

-First name, last name -Business email (verified) -Company name + domain -Title + department + country/region -Source + verification status

Clean, verified data = fewer bounces, better inboxing, higher replies—and your microsites get in front of the people who'll actually book the meeting.
