OB/GYN Email List | 140,414 Verified Contacts | SparkDBi

Trusted by 2,600+ world-class brands and organizations

SparkDBi maintains a verified OB/GYN email list covering 140,414 obstetricians, gynecologists, maternal-fetal medicine specialists, gynecologic oncologists, reproductive endocrinologists, and certified nurse midwives across the United States. Every contact is sourced from multiple vetted channels including conference and CME partnerships, state and national professional associations, and healthcare publication networks, then validated through email inbox verification, phone validation, and physical address confirmation before delivery. The database refreshes monthly.

OB/GYN is one of the most commercially diverse specialties in medicine. Women's health drug companies, fertility clinics, maternal-fetal medicine device manufacturers, gynecologic oncology pharmaceutical teams, and contraceptive manufacturers all need verified contact data for the right OB/GYN subspecialist at the right institution. The 15 subspecialties in the SparkDBi database cover the full range of that commercial demand.

Who Uses the OB/GYN Email List

Women's health pharmaceutical companies use the OB/GYN list for outreach across menopause hormone therapy, contraceptive products, uterine fibroid treatments, and endometriosis drugs. Elagolix (Orilissa), relugolix combination therapy (Myfembree), and progesterone formulations are active commercial categories. Each requires specific OB/GYN subspecialty targeting to reach the prescribers most likely to initiate therapy.

Gynecologic oncology drug companies use the list for outreach to gynecologic oncologists managing ovarian, cervical, endometrial, and vulvar cancers. PARP inhibitors (olaparib, niraparib, rucaparib) for BRCA-mutated ovarian cancer, pembrolizumab for cervical and endometrial cancer, and tisotumab vedotin (Tivdak) for cervical cancer are all active commercial programs targeting this subspecialist population.

Fertility and reproductive medicine drug companies target reproductive endocrinologists for outreach on ovarian stimulation protocols, IVF support medications (gonadotropins, progesterone, GnRH agonists and antagonists), and infertility diagnostics. The fertility drug market has grown significantly with increased IVF utilisation rates across most US markets.

Medical device companies use the OB/GYN list for outreach to obstetricians and maternal-fetal medicine specialists who select fetal monitoring systems (Philips, GE Healthcare), ultrasound platforms, and delivery room equipment. Minimally invasive surgery platforms (robotic and laparoscopic systems for hysterectomy, fibroid removal, and endometriosis surgery) also require targeted OB/GYN surgeon outreach.

Contraceptive manufacturers and long-acting reversible contraceptive (LARC) device companies use the list for general OB/GYN outreach across IUD insertion training, new device launches, and patient counselling program support.

OB/GYN Subspecialties and Verified Contacts

The SparkDBi OB/GYN database covers 15 subspecialties across the full OB/GYN care team. All subspecialties are available as individual segments or combined with subspecialty flags.

Key Drugs, Devices and Clinical Areas

Gynecologic oncology is the highest-commercial-intensity subspecialty within OB/GYN. PARP inhibitors have become standard of care in BRCA-mutated ovarian cancer, with olaparib (Lynparza), niraparib (Zejula), and rucaparib (Rubraca) all competing for gynecologic oncologist prescribing decisions. Pembrolizumab has approvals in cervical and endometrial cancer. Bevacizumab remains standard in platinum-sensitive ovarian cancer relapse. These programs require direct outreach to the 905 gynecologic oncologists in the SparkDBi database.

Uterine fibroids and endometriosis are large-market conditions with growing pharmaceutical activity. GnRH receptor antagonists elagolix (Orilissa) and relugolix combination (Myfembree) address both conditions. Surgical fibroid management (myomectomy, hysterectomy) drives demand for minimally invasive surgical platforms. General and specialist OB/GYNs managing these conditions are the target audience for both drug and device outreach programs.

Maternal-fetal medicine specialists manage high-risk pregnancies and are the audience for fetal monitoring technology, antenatal corticosteroids, progesterone supplementation for preterm birth prevention, and newer treatments for postpartum haemorrhage and maternal hypertension.

Contraception and family planning product companies target the broad general OB/GYN population for combined oral contraceptive launches, IUD training programs, and long-acting reversible contraceptive education initiatives.

Data Provenance for the OB/GYN Dataset

The OB/GYN file draws on conference attendance and CME participation records supplied by healthcare education partners, membership directories from state and national OB/GYN associations, subscriber lists from women's health publication networks, and matches produced through SparkDBi's B2B2C verification partnerships. These are the working sources, updated on a rolling basis rather than pulled once and left static.

Federal registries such as CMS and NPPES are checked against these records for cross-reference purposes only. They are not treated as a system of record, since practice moves, retirements, and license changes routinely outpace how current those registries stay.

Every physician record then goes through mailbox-level email verification, phone number validation, and physical address confirmation covering both practice and home addresses. Records that fail any of these checks are removed and re-verified in the following month's refresh rather than left in the file.

NPI Taxonomy Codes for OB/GYN

CMS NPI taxonomy codes for reference. These are useful when specifying subspecialty requirements for a data order or verifying provider credentials independently. SparkDBi cross-references these as one of several validation inputs:

Practice Setting Breakdown

OB/GYN has a distinctive mix of hospital-based and independent practice. About 55% of OB/GYN physicians in the SparkDBi database practice in hospital-employed or academic settings. The remaining 45% are in private OB/GYN groups, multispecialty women's health practices, or fertility clinic settings. Hospital-employed OB/GYNs tend to be in academic medical centres or large integrated delivery networks. Reproductive endocrinologists and fertility specialists are more often in dedicated fertility clinic settings.

Gynecologic oncologists are concentrated in cancer centres and academic medical centres, with the highest density at NCI-designated comprehensive cancer centres and major university hospitals.

Top 10 Hospitals for Obstetrics and Gynecology (2026 World Rankings)

Rankings from the Newsweek World's Best Specialized Hospitals 2026 report. SparkDBi maintains verified contact data for OB/GYN specialists affiliated with each institution.

Geographic and International Coverage

The US OB/GYN database covers all 50 states. Highest concentrations are in California, Texas, New York, Florida, and Illinois, reflecting population density and the locations of major academic women's health programmes.

International OB/GYN data is available for the UK, Italy, Germany, Canada, Spain, and Australia. Contact SparkDBi for current counts by country and by subspecialty.

Deliverability and Inbox Placement

OB/GYN physicians at academic medical centres and hospital systems use enterprise email environments. Gynecologic oncologists at major cancer centres face particularly tight filtering. Private-practice OB/GYNs and fertility clinic physicians use practice-domain email with lighter filtering, generally producing better inbox rates. SparkDBi flags enterprise vs independent domains in delivered datasets so buyers can segment send strategies accordingly.

Data Enrichment and Available Fields

For existing contact lists, SparkDBi can append or verify: NPI numbers (where applicable), subspecialty classifications, hospital affiliations, email addresses, phone numbers, work practice addresses, home addresses, and personal email addresses. Match rates average 74% against the full database.

Compliance

The SparkDBi OB/GYN email list contains no patient data. All records are professional contact information for licensed OB/GYN providers. The database is HIPAA-aligned, CAN-SPAM compliant, and CCPA-aware. Business Associate Agreements are available on request.
