What emailverifier.dev is
emailverifier.dev checks email addresses before they enter product workflows such as signups, lead forms, free trials, and CRM imports. Its checks cover address structure, likely typos, mail-routing DNS, provider type, disposable or role-based status, and mailbox acceptance or catch-all behavior when available. Results distinguish deliverable, risky, undeliverable, and unknown addresses, keeping uncertain checks separate from confirmed failures. Domain reports classify providers as disposable, known free mailbox services, or neither, with risk and routing details. Teams can use a REST API, a remote MCP server with verify_email and check_domain tools, or a public demo that requires no key. Each verification or domain check uses one project credit; the demo allows 10 checks per hour without consuming credits. Bulk jobs accept CSV or TXT files or pasted addresses, handle up to 5,000 unique addresses, and retain the original rows with added results. Completed bulk files expire after seven days. The free plan includes 1,000 starter credits and one API key per project. A 20,000-credit pack costs $10, paid once-time purchase.
