Frequently asked questions
What is EmailCheck?
EmailCheck is an email verification service that checks any address for validity, disposable/temporary domain, MX record, spam risk, domain age and more. Call it via REST API, upload CSVs from the dashboard, or run a deep SMTP reachability check on your most valuable addresses.
Is EmailCheck really free?
New registered users receive 30 free credits with no credit card required. After that, purchase a one-time credit pack or subscribe monthly to continue.
What's the difference between email check and reachability check?
Email check is a fast verdict based on syntax, MX records, disposable lists, spam signals and typo detection — milliseconds per call. Reachability check opens a real SMTP conversation with the mail server to confirm the mailbox actually accepts mail: slower, deeper, and the right tool to run before sending to a high-value address.
How does disposable email detection work?
EmailCheck cross-references the email domain against an up-to-date database of known temporary and throwaway mail providers, returning a boolean disposable field in the API response in real time.
What does the API response include?
The response includes MX record status, disposable flag, spam risk, blocklist status, domain age, domain authority, role account detection, alias detection, normalized email, and a spelling suggestion when a typo is detected.
Do I need to sign up to use the API?
You can verify any email instantly on the homepage with no account. To get a persistent API key, usage tracking and higher quotas, create a free account in under a minute.
