How Contact Enrichment Works for Recruiters
Recruitment contact enrichment typically uses a multi-provider waterfall: the system queries cached data first (free), then premium providers in sequence until a verified result is found. This approach minimises cost while maximising coverage. A typical waterfall checks company records, then email pattern databases, then phone directories, then live verification services.
The enrichment process for a single contact usually takes 2-5 seconds and follows this sequence:
- Cache check — previously found data is returned instantly at zero cost
- Email pattern matching — generates likely email patterns (first.last@, f.last@) and verifies via SMTP
- Provider lookup — queries data providers for verified email and phone
- Verification — validates email deliverability via MX record and SMTP checks
Email Enrichment vs Phone Enrichment
Email enrichment has a higher success rate (70-85% for Australian business contacts) and lower cost per match than phone enrichment (40-60% success rate for direct dials). Most recruitment agencies start with email enrichment for outreach campaigns, then use phone enrichment selectively for high-value prospects where a direct call would accelerate the sales cycle.
Choosing an Enrichment Provider for Australian Recruitment
Australian-specific considerations when choosing enrichment tools:
- +61 number coverage — many US-built tools have poor Australian mobile number coverage
- Toll-free filtering — reject 1800/1300 numbers that reach switchboards, not decision-makers
- ASIC/ABR integration — Australian company data from government registries is more reliable than scraped sources
- Verification accuracy — check provider claims against your own domain; catch-all domains inflate reported accuracy
