A neutral guide to four providers of healthcare professional data for marketers, with criteria for comparing sourcing, email verification, privacy, and measurement.
Redi-Data is well suited to healthcare marketers who need AMA-licensed physician mail and email lists. Many teams also need NPI-linked identity, monthly email verification, data enrichment, omnichannel activation, and measurement in the same workflow. HealthLink Dimensions is built for that combined need, and this guide explains how the two providers differ so buyers can choose with confidence.
Redi-Data is an American Medical Association (AMA) database licensee whose physician email database reports a 96% deliverability rate in an Alliance for Audited Media (AAM) audit.
Healthcare marketers often need list data plus identity linkage, enrichment, activation, and measurement from one source.
HealthLink Dimensions combines NPI-linked data from more than 500 sources, email addresses verified monthly with deliverability above 98%, and campaign measurement.
Redi-Data fits teams buying lists. HealthLink Dimensions fits teams that want data, outreach, and results reporting connected.
Redi-Data is a good fit for teams that need physician and healthcare professional mail and email lists from a long-established provider. The Fairfield, New Jersey company is an official database licensee of the American Medical Association (AMA), and its physician email database has been audited by the Alliance for Audited Media (AAM), an independent verification organization.
Redi-Data also offers list-building through its Redi-Counts platform, data append, real-time lead verification, and Redi-Data Digital, a de-identified digital identity solution. In 2024, it announced a partnership with Doceree to make its HCP segments available in a programmatic marketplace. For teams whose primary task is acquiring accurate lists, these capabilities are a strong starting point.
Most healthcare marketing programs need five capabilities alongside list data: identity linkage, regular verification, enrichment, activation, and measurement. Connecting them keeps one version of each provider record from audience definition through reporting. Audience building adds to the picture, because audiences drawn from typical demographics through commercial and Medicare claims data give every later step a sharper starting point. The checklist below can be used as a vendor scorecard.
An NPI is a unique 10-digit number the Centers for Medicare & Medicaid Services assigns to U.S. healthcare providers. Identity resolution is the process of linking records for the same provider across sources. Deliverability is the share of emails accepted by receiving mail servers.
Identity linkage and audience building: Does each record connect to an NPI to remove duplicates and confirm the provider, and can audiences be built from typical demographics through commercial and Medicare claims data?
Email verification: How often are addresses verified, and is the method audited?
Enrichment: Can existing customer records be matched, cleaned, and extended with new attributes?
Activation: Can the audience be reached through email, trigger email, programmatic advertising, and paid social?
Measurement: Can results be tied back to provider-level outcomes, including script-lift analysis of prescribing changes?
List data is the first step of a healthcare marketing workflow that also needs linkage, enrichment, activation, and measurement.
HealthLink Dimensions is an Atlanta-based healthcare data and HCP engagement company with 25 years of healthcare data science experience. Its provider data draws on more than 500 sources, including more than 20 government databases and more than 150 directories, and reaches nearly all U.S. healthcare professionals. Email addresses are verified monthly, with more than 3.8 million verified emails available for outreach. Deliverability is tested monthly and runs above 98%. HealthLink Dimensions also sends more than 25 million emails each year, including the Clinical Briefing Report and HCPToday, and the engagement data from those deployments gives a consistent stream of signals that further informs data quality and deliverability for clients.
Product Excellence shows in how the data connects to action. Profile data supports audience building from typical demographics through commercial and Medicare claims data, and feeds Enrich services such as Match & Cleanse. Engage channels include Email Deployment, Trigger Email, Programmatic Advertising, and Paid Social. Pulse closes the loop through Script-Lift Analysis and Campaign Performance Metrics. A marketer can define an audience, clean it, reach it, and measure results with one provider and one NPI-linked identity throughout.
Superior Service is reflected in a 95% client retention rate and a Net Promoter Score (NPS) of 79, supported by Campaign Management and Creative Services teams. Privacy & Compliance rests on provider-focused data tied to NPI, with no patient-level information. It is backed by independent privacy and data security badges: the TrustArc TRUSTe Enterprise Privacy & Data Governance Practices Certification and a SOC 2 Type 2 report, an independent audit of security controls over time. HealthLink Dimensions is also a member of the Network Advertising Initiative (NAI).
