Doctor Email List sells US physician and clinician contact lists as one-time CSV downloads, one file per medical specialty. There are 36 files covering 1,190,183 clinicians counted once each by NPI: 31 physician specialties plus podiatrists, nurse practitioners, physician assistants, chiropractors and optometrists. Each file starts from the CMS Doctors and Clinicians national file (release dated Aug 18, 2026) and the NPPES registry: name, credential, NPI, practice name, phone, address, medical school and graduation year. We add the practice website and an email address only where one was found and passed an SMTP check, printed with its check date. Email coverage is partial. A specialty file costs $295 and all specialties cost $995, paid once with no subscription. If more than 5% of the verified emails hard-bounce on your first send within 30 days, the list price is refunded. Practice contact data only: no patient data, no home addresses. Physicians can opt out by NPI.
