Physician Email Data by Specialty, Verified and NPI-Matched
Verified physician email contacts by specialty, NPI-matched, and Monthly Refresh.
Trusted by Global Clients and Agencies
Physician contacts by specialty: verified counts
All counts from March 2026 delivery. Email accuracy verified at 94-96% per specialty.
When a pharma brand team, a CME provider, or a healthtech company needs to reach physicians, the first question is always the same: how many verified contacts exist in this specialty, and how accurate are the emails?
EmailAddress.ai publishes actual verified contact counts by physician specialty, not estimates, not ranges. Exact counts from a database refreshed on a Monthly Refresh cycle, cross-referenced against the CMS NPI registry, and verified for email deliverability before delivery.
Physician email data is a licensed dataset of verified professional email addresses for medical doctors and advanced practice providers, organized by specialty, sub-specialty, state, and NPI. EmailAddress.ai's physician database covers 28 specialty groups with 94-96% verified accuracy, NPI cross-matching on 2.5M+ records, and Monthly Refresh cycles.

What makes this data usable, not just large
A list of 134,470 internists is only as valuable as the deliverability of the email addresses it contains. EmailAddress.ai applies three verification layers before delivery that most physician data providers skip entirely.
NPI cross-matching
2,587,330 physician and advanced practice records are matched against the current CMS NPI registry. Records that do not match an active NPI are flagged and reviewed before inclusion. NPI matching catches name variations, credential changes, and retired practitioners that would otherwise remain in the dataset as dead weight.
Email deliverability verification
Every physician email address passes through our own catch-all email verification engine, the same engine that powers our email verification product. Catch-all domains, common in hospital and group practice environments, are resolved using our multi-step SMTP validation process. The result is 94-96% verified accuracy on delivered physician records.
Monthly Refresh
Physician contact data has a documented decay rate, practitioners retire, relocate, change affiliations, and shift specialties. Our Monthly Refresh of the full dataset, combined with continuous NPI registry monitoring between cycles, keeps the dataset current in a way that annual refresh cycles cannot.
How physician email data is licensed
Physician email data is available as a one-time licensed extract, an API-accessible query, or a CRM-integrated recurring delivery. Common use cases include:
Pharma approved email
Specialty-segmented physician lists delivered in Veeva-compatible field format, with NPI as the primary matching key for CRM deduplication.
Medical education outreach
CME providers and medical publishers licensing physician email data for specialty-specific newsletter recruitment, continuing education invitations, and conference announcements.
Healthtech sales and marketing
EHR vendors, medical device companies, and digital health platforms building physician prospect lists by specialty, practice size, and geography.
CRM enrichment and match-and-append
Health systems, IDNs, and payer organizations enriching existing provider records with missing email addresses, updated specialty classifications, and NPI verification.
Compliance note for physician data
Physician email data licensed from EmailAddress.ai covers professional contact information only, name, specialty, NPI, professional email address, practice affiliation, and address. The dataset does not include patient data, prescribing records, or any clinical information.
All physician data licenses include lawful-basis documentation covering GDPR (for international records), CCPA, and HIPAA-adjacent standards for data handling. We do not claim HIPAA certification. Buyers are responsible for their own compliance obligations for their specific outreach use case.
