Lead list matching
Don't sell to customers you already have.
You bought a lead list, downloaded a trade-show export, or got a list from a partner. Before handing it to sales, match it against your CRM — so reps don't call existing customers as cold leads, don't re-pitch active opportunities, and don't skip the 20% of the list that's already convertible.
The problem
Every lead list you buy overlaps your CRM. You just don't know which rows.
Purchased lists from ZoomInfo, Apollo, Cognism, or Clearbit have significant CRM overlap — 15-40% is typical. Sales doesn't know which leads to skip.
A rep cold-calls an existing customer, pitches them as net-new, and embarrasses the account team.
An open opportunity gets a marketing sequence from the lead list — the prospect gets two emails with different messaging.
Reps waste time enriching records that already exist (just with different formatting).
Deduping manually in Excel with VLOOKUP misses 70%+ of real matches because it requires perfect text match.
How the Genie solves it
Match new leads against your CRM in minutes, not hours
Email + phone + name + company
The engine matches on whichever identifiers you have. Email + company is the strongest signal; name + company works when emails are missing; phone works for B2C or mobile-first lists.
Company name variations
'Acme Corp', 'Acme Corporation', 'Acme', 'ACME, Inc.' — all recognized as the same company. Handles legal suffix variations (LLC / Inc. / Ltd.) and common abbreviations.
Three-bucket output
Every row comes back as matched (already in CRM — skip), review (possibly in CRM — check), or unmatched (genuinely new — call). Sales knows exactly which rows to work.
Account-level matching
Match at the company level too — so if you already have a different contact at Acme Corp, the lead gets flagged as 'existing account, new contact' instead of 'net-new'.
No CRM integration required
Export your CRM contacts once, upload both files, get the match. No OAuth, no package installs, no admin approvals.
Repeatable in minutes
Next lead list you buy? Upload it + your CRM export. 3-minute workflow. Scales to 500K-row lists.
Real example
A purchased ZoomInfo list matched against Salesforce
Same workflow regardless of list source — lead providers all export similar schemas.
Source file
zoominfo_export.csv · first_name, last_name, email, company
Master file
salesforce_contacts.csv · first_name, last_name, email, company
Sarah Patel · sarah.patel@globex.com · Globex Inc
Sarah Patel · spatel@globex.com · Globex
matchedSame name, email local-part is a common alias (first.last vs flast), company name variation recognized — skip this lead, she's already a customer
David Kim · dkim@initech.co · Initech
(no match)
unmatchedGenuinely new — hand to sales as net-new lead
Michelle Wong · — · Wayne Enterprises
(no match)
reviewNo email in the source row; Wayne Enterprises is in your CRM but with different contacts. Review manually to decide if this is an existing account or a new one
Before and after
What changes when you use ListMatchGenie
Without ListMatchGenie
- Rep calls 'John Smith' at Acme as a cold lead → finds out Acme is already a paying customer. Embarrassment.
- Marketing emails 'Jane Doe' at widget.co with a 'welcome to our list' sequence. She's been a customer for 3 years.
- 15-40% of purchased list is wasted effort; nobody knows which rows.
- Manual dedup in Excel with VLOOKUP only catches exact email matches — you miss most of the overlap.
With ListMatchGenie
- Every lead row is tagged matched / review / unmatched before sales sees it.
- Reps only work genuinely new leads — no embarrassing cold calls to existing customers.
