DataZapp

What Is DataZapp?

DataZapp is a marketing data platform that specializes in phone and email append services — the process of adding missing contact details to a list of names and addresses. For real estate wholesalers, this means uploading a property owner list and receiving back cell numbers, landlines, and email addresses at a low per-record cost.

The platform operates on a pay-as-you-go model starting at around $0.03 per matched record. There's no monthly subscription required, which makes it practical for wholesalers running occasional campaigns rather than continuous operations.

DataZapp also offers a mobile app called REI-Vision for driving-for-dollars workflows, letting you trace individual addresses in the field. Beyond real estate, they serve political campaigns, home services, and B2B markets — real estate is one vertical among several.

Who Is DataZapp Best For?

DataZapp is a strong fit for wholesalers and real estate investors who need to append contacts to large mailing or cold calling lists cheaply. If you're buying a 10,000-record tax-delinquent list and want to add phone numbers before dialing, DataZapp's per-record pricing makes bulk processing affordable.

It works well as a secondary data source too — run your list through DataZapp to fill gaps left by a primary skip tracer. The REI-Vision mobile app is a nice bonus for investors who regularly drive neighborhoods.

If you need deep investigative skip tracing for a specific hard-to-find owner, a more specialized tool may return better results. DataZapp excels at speed and volume, not complex individual traces.

Our Verdict

DataZapp is a budget-first choice for bulk phone and email appends. The pay-as-you-go pricing removes commitment risk, and the $0.03 per-match rate is competitive for large lists. The trade-off is that it's a commodity data append tool, not a wholesaling-specific platform. Expect straightforward results without the investor-oriented coaching or integrations that niche tools offer.
