Data Deduplication
Data deduplication finds and merges duplicate records so the same person or account exists exactly once in your system — the prerequisite to accurate reporting and routing.
What is data deduplication?
Data deduplication (dedup) is the process of identifying records that represent the same real-world entity and merging or eliminating the extras. In a CRM, that's usually one record per person and one per account, even if the source data has the same person spelled three ways or the same company with two different domains.
Why it matters
- Dupes corrupt every metric that uses unique counts (lead volume, conversion, MRR per account)
- Routing breaks when two reps own two copies of the same lead
- Compliance breaks when an unsubscribe applies to one record but not the dupe
Matching strategies
- Exact match — work email, primary domain, phone — fast and high-precision
- Fuzzy match — Levenshtein on names, normalized domains, geocoded addresses — catches the soft dupes
- Probabilistic / ML match — combines signals into a confidence score; tune the threshold
How TexAu helps
Dedupe inside a TexAu table before push to the CRM — match on email + domain + normalized name, merge per your rules, and write only canonical records downstream.
