Proprietary Algorithm + Waterfall Fallback

Our enrichment engine uses a proprietary algorithm to locate emails. When our primary system doesn't find a result, we cascade through a waterfall of secondary sources maximizing match rate without extra work on your side.

Proprietary Algorithm + Waterfall Fallback

Reverse Email Lookup

Already have an email address? Run it in reverse. Crustdata resolves an email back to a full professional profile name, title, company, and 90+ additional datapoints.
