Alliance has confirmed year over year improvements in deliverability and clinician identity accuracy as HealthLink continues to refine and verify its national healthcare provider database.
Accurate healthcare provider data is the foundation of effective healthcare marketing. Marketers depend on the ability to reach verified clinicians with confidence, and that level of precision requires constant attention to data quality, identity resolution, and independent validation. HealthLink Dimensions prioritizes these standards through its data governance framework and annual audits conducted by the Alliance, formerly BPA Worldwide. Their independent certification provides transparency into the accuracy, completeness, and readiness of the HealthLink provider database.
Deliverability Has Risen for Three Consecutive Years
The most notable trend in the past three Alliance audits is the consistent increase in email deliverability. The Alliance validated the following progression:

-
2023: 90.3 percent
-
2024: 96.1 percent
-
2025: 98.4 percent
This improvement reflects ongoing investment in verification practices, including monthly re checks using trusted deliverability partners and real world engagement feedback from more than 20 million email deployments each year. These practices raise deliverability, improve long term communication performance, and protect the sender reputation of marketers deploying campaigns through their own systems. High deliverability ensures greater inbox placement and more reliable outreach to clinicians across specialties and care settings.
High Identity Accuracy and a Continuously Refined Provider Database
Alliance audits have consistently confirmed that more than 94 percent of all email addresses in the HealthLink database link to a verified clinician identity. This level of accuracy supports precise segmentation and NPI level targeting across email, programmatic, and social channels. HealthLink maintains both professional and personal email addresses for clinicians, which increases reach and supports better engagement across multiple practice environments.
The database is refined continuously to reflect the realities of the clinical workforce. Every month, two to 2.5 percent of providers change roles, locations, affiliations, or retire. New clinicians also enter practice. HealthLink updates the Golden Provider Record for each clinician daily to reflect these shifts, ensuring that only current and contactable providers remain in the master dataset. Alliance audits confirm that this active curation process maintains accuracy at national scale.
What These Improvements Mean for Healthcare Marketers
Accurate and continually verified provider data produces measurable value across campaigns and channels. Improved deliverability and high identity match rates help healthcare marketers:
-
Reach clinicians reliably across email, programmatic, and paid social
-
Protect sender reputation and reduce bounce related disruption
-
Reduce waste and improve return on media spend
-
Activate precise, compliant audience segments
-
Trust that their targeting is based on independently validated data
This foundation strengthens performance across all four HealthLink product families. It improves HealthLink Profile and Enrich data feeds, enhances activation through HealthLink Engage marketing channels, and increases the accuracy of measurement and attribution in HealthLink Pulse.
Looking Ahead
HealthLink will continue investing in verification, identity resolution, and daily data maintenance to keep its provider database accurate and activation ready. Independent audits by the Alliance remain an important part of that commitment. Three consecutive years of improvement demonstrate that HealthLink’s approach produces results. Deliverability is rising, identity accuracy remains strong, and the database continues to reflect the most complete and current view of the U.S. clinician population.
Healthcare marketers depend on accurate data to reach the audiences that matter most. And independent Alliance audits confirm that HealthLink delivers the accuracy, transparency, and measurable improvement required to support successful clinician engagement strategies.
