Quick answer: Therapist email list providers supply contact data for licensed therapy professionals, such as mental health counselors, marriage and family therapists, psychologists, physical therapists, occupational therapists, and speech-language pathologists. The right provider depends on which therapy professions you need, how records are verified against state licenses or NPI data, how often they are refreshed, and whether you need a campaign-ready list or platform access.
This guide compares the main sources of therapist data, lists the questions to ask before you buy, and gives a simple test to run on any provider’s sample. For an overview of the therapist audience itself, see our therapist email list guide.
