Midwife Email List
Midwifery data is one of the most fragmented segments in healthcare provider intelligence. Between Certified Nurse-Midwives, Certified Professional Midwives, and Certified Midwives, three different credential types with different licensing, different databases, and different practice settings all serve the same patient population. Building an accurate midwife list means navigating all three.

Why Midwife Data Has Coverage Gaps
The midwifery workforce is divided across three primary credential types, each with its own regulatory framework. Certified Nurse-Midwives (CNMs) are the largest group, with approximately 12,000 active practitioners according to the American College of Nurse-Midwives. CNMs are advanced practice registered nurses with graduate-level education who can prescribe medications and practice in hospitals, birth centers, and home settings. They appear in the NPI registry and have taxonomy codes.
Certified Professional Midwives (CPMs) number roughly 3,000 active practitioners. CPMs are credentialed through the North American Registry of Midwives (NARM) and primarily attend births in home and birth center settings. Here's the critical data gap: most CPMs do not have NPI numbers because they don't bill insurance through the NPI system. They're invisible to any data vendor that relies solely on the CMS NPI Registry. If your product serves the out-of-hospital birth market, an NPI-only list misses a substantial portion of your target audience.
Certified Midwives (CMs) are the smallest group, recognized in only a handful of states. CMs have the same graduate-level education as CNMs but come from non-nursing backgrounds. Their small numbers and limited state recognition mean they're often absent from both nursing and medical databases.
Practice setting fragmentation compounds the data challenge. CNMs in hospital systems are buried in OB/GYN department listings alongside obstetricians, nurse practitioners, and physician assistants. Their individual contact information is locked behind institutional directories. CNMs in birth centers and home birth practices are easier to identify individually but may not maintain traditional office addresses or practice websites. CPMs in home birth practice often operate from their residences with no commercial address at all.
What a Midwife List Includes
NPI number (where available) and credential type. CNMs have NPI numbers and nurse-midwife taxonomy codes in the CMS NPI Registry. CPMs and CMs often do not. A comprehensive midwife list must source CPM data from NARM certification records, state licensing databases, and birth center affiliation records rather than relying on NPI alone.
Credential classification: CNM, CPM, or CM. This distinction matters for targeting. CNMs prescribe medications, work in hospitals, and make clinical purchasing decisions similar to other advanced practice providers. CPMs work in out-of-hospital settings and purchase birth supplies, fetal monitoring equipment, and practice management tools for independent practice. Your product dictates which credential type you need.
Verified email. Hospital-employed CNMs have institutional email addresses with the same gatekeeper challenges as other hospital-based providers. Birth center CNMs and CPMs typically have practice-domain or personal business emails that are more directly accessible. We verify deliverability at the mail-server level for all records.
Practice setting. Hospital, freestanding birth center, home birth practice, community health center, or OB/GYN group practice. Practice setting determines product needs: hospital-based CNMs use institutional equipment and supplies, while birth center and home birth midwives purchase their own portable equipment, birth supplies, and fetal monitoring devices.
Birth center affiliation. For midwives practicing in birth centers, the affiliated center is identified. Birth centers are growing in number (roughly 400 accredited centers in the US) and represent concentrated purchasing opportunities for birth supply companies, equipment vendors, and EHR providers specializing in midwifery workflows.
State licensing status. Midwifery licensing varies dramatically by state. Some states license all three credential types. Others only recognize CNMs. A few states have no licensing pathway for CPMs at all. State-level licensing data helps vendors understand where their target midwife population is legally practicing and which states have the densest midwife presence.
Common Data Problems with Midwife Lists
The most widespread problem is CNMs being buried in hospital OB/GYN department listings. When a CNM works for a hospital system, their name appears alongside obstetricians, maternal-fetal medicine specialists, and OB/GYN nurse practitioners in the department directory. Data vendors that scrape hospital websites may categorize the entire department as "OB/GYN providers" without distinguishing CNMs from physicians or NPs. If your product is specific to midwifery practice (birth balls, midwifery-specific EHR modules, independent practice tools), reaching the CNMs within a hospital OB/GYN department requires credential-level filtering that most databases don't provide.
CPMs are systematically missing from NPI-based databases. Since most CPMs don't participate in insurance billing, they don't have NPI numbers and don't appear in the CMS registry. A data vendor that builds their midwife list from NPI data alone captures CNMs but misses the entire CPM population. For companies selling home birth supplies, portable fetal monitoring equipment, or birth center management tools, CPMs are a primary customer segment that NPI-only sourcing can't reach.
Confusion with doulas inflates midwife lists. Doulas provide emotional and physical support during labor but aren't healthcare providers, don't deliver babies, and don't prescribe medications. Some data vendors classify doulas as "birth professionals" alongside midwives, or tag doulas with midwifery-related keywords scraped from their websites. A doula cannot use medical equipment, prescribe supplements, or make clinical purchasing decisions. Including doulas in a midwife list wastes outreach on contacts who aren't your market.
Address data is particularly unreliable for home birth midwives. A CPM or CNM in home birth practice visits patients' homes and may not have a dedicated office address. Their NPI address (if they have one) might be a home office, a PO box, or a birth center where they have privileges but don't maintain a full-time presence. Traditional address-based territory mapping doesn't work well for this segment of midwifery.
How Provyx Builds Midwife Lists
Provyx builds midwife lists from multiple data sources because no single database captures the full midwifery workforce. We start with the CMS NPI Registry for CNMs, filtering by nurse-midwife taxonomy codes. Then we supplement with NARM certification data for CPMs, state midwifery licensing databases, birth center affiliation records, and professional association membership data.
Credential-type classification is applied to every record. Each midwife is tagged as CNM, CPM, or CM based on their credentialing body and state license type. This lets you target the specific credential segments relevant to your product. A pharmaceutical company needs CNMs (who prescribe). A birth supply company may want both CNMs and CPMs. A birth center management platform wants midwives affiliated with freestanding centers regardless of credential type.
Practice setting identification goes beyond what NPI data provides. We classify each midwife's practice environment based on their employer, birth center affiliation, and practice type indicators. Hospital-employed CNMs are tagged separately from independent practice CNMs, birth center CNMs, and home birth midwives. CPMs are classified by primary practice setting (birth center vs. home birth) and geographic coverage area.
Every email is verified for deliverability. CAN-SPAM compliance is built into our data handling. Delivery is in CSV or Excel format, filterable by credential type, practice setting, birth center affiliation, state, and geographic area. Whether you're a prenatal supplement company, a fetal monitoring equipment vendor, a birth center management software provider, or a midwifery continuing education organization, the list covers the specific midwife segment you need to reach.
Frequently Asked Questions
How many midwives are there in the United States?
There are approximately 12,000 Certified Nurse-Midwives (CNMs) and roughly 3,000 Certified Professional Midwives (CPMs) in the US, for a combined total of about 15,000. Certified Midwives (CMs) add a small number in the few states that recognize the credential. The CNM count is more precise because CNMs are in the NPI registry; CPM counts are estimated from NARM certification data and state licensing records.
What's the difference between a CNM and a CPM for targeting purposes?
CNMs are advanced practice registered nurses who can prescribe medications, practice in hospitals, and bill insurance. They're reachable through NPI data and hospital directories. CPMs are credentialed through NARM, primarily attend births at home and in birth centers, and most don't have NPI numbers. For pharmaceutical or clinical products, target CNMs. For home birth and birth center supplies, include both CNMs and CPMs.
Can you include birth center facility data?
Yes. We identify freestanding birth centers and their affiliated midwives. There are roughly 400 accredited birth centers in the US, and we capture facility name, location, affiliated midwives, and contact information. Birth centers are valuable targets for supply vendors, equipment companies, and EHR/practice management software providers.
What companies typically buy midwife email lists?
Common buyers include prenatal vitamin and supplement companies, birth supply distributors, fetal monitoring equipment vendors, birth center management software providers, midwifery-specific EHR vendors, childbirth education programs, midwifery continuing education organizations, and maternal health nonprofits. Pharmaceutical companies also target CNMs specifically for prescribing-related outreach.
