Match rate is the percentage of records you submit for enrichment that a data provider can successfully match against their database and return results for. If you send 10,000 contacts and the provider finds and enriches 7,500, the match rate is 75%. Match rate is the single most important metric for evaluating an enrichment provider because it directly determines how many records you'll actually get data back on.
Why It Matters
A provider with amazing data quality but a 30% match rate leaves 70% of your database untouched. High match rates matter because the records you most want enriched, the ones missing data, are often the hardest to match. Using multiple providers in a waterfall approach (trying the next source when the first one doesn't match) can push overall match rates from 60% with a single provider to 85%+ with three.
What Affects Match Rate
- Input data quality: Records with full names and company domains match better than records with just an email or just a name
- Provider coverage: Each provider has different strengths. Some cover SMB better, others enterprise. Some are strong in US, others internationally
- Record freshness: People who changed jobs recently may not appear in the provider's database yet. Newer data matches worse
- Industry coverage: Some providers have deep coverage in tech/SaaS but thin coverage in healthcare, manufacturing, or government
- Waterfall strategy: Using multiple providers sequentially improves overall match rates by catching records that any single provider misses
Example
A company sends 20,000 contacts to Provider A. Match rate: 65%. They send the 7,000 unmatched records to Provider B. Match rate on the remainder: 45%. They send the remaining 3,850 to Provider C. Match rate: 30%. Combined match rate across all three: 87%. Single-provider would have been 65%. The waterfall approach found 4,400 additional matches.
