Use the signal when deciding whether an account needs another contact method. Avoid describing every match as fraud.
Frequently refreshed domain data
Disposable email checker
Check whether an address is tied to a known temporary or throwaway email provider.
What is a disposable email address?
Disposable email services provide temporary inboxes that can be used for one-time registrations or short-lived messages. They can be technically deliverable while still being poor-quality addresses for accounts, CRMs or mailing lists.
How this checker works
EmailValidly checks the submitted domain against a large community-maintained disposable-domain blocklist loaded into the production verifier and refreshed periodically. A domain not appearing in the list is not a guarantee that it will never behave like a temporary-email service, but known disposable providers are flagged immediately.
Put the result to work
Treat a blocklist match as one piece of evidence
This tool compares the address domain with a disposable-domain dataset. It is useful for spotting known temporary-mail services, but neither a match nor an absence from the list identifies the person behind an address.
Submit one address
Use the actual address supplied by the visitor or contact.
Read the match wording
A match means the domain appears in the dataset. No match means only that it was not found.
Choose a proportionate response
For accounts needing durable access, ask for an alternative or use an ownership confirmation flow.
Worked examples
What the evidence tells you
Illustrative scenarios, not live results for the addresses or records shown. Open a scenario to see the next action.
01Domain appears in the dataset
Disposable-domain match
The service is on the current list. Some people use temporary mail for privacy rather than abuse.
Next action Explain why a lasting address is needed.
02Domain is absent from the dataset
Not found in blocklist
A newly launched or private temporary-mail service may not be listed.
Next action Combine with your normal account checks.
03Custom forwarding address
Not necessarily disposable
Forwarding and aliases can provide long-term delivery while hiding a personal inbox.
Next action Do not equate privacy with a throwaway address.
Use it with a purpose
Where this tool fits
Contact-list review
Mark matched domains for review so the list owner can decide whether those records still belong.
Before you decide
Questions about this tool
Can the list catch every temporary domain?
No. New domains appear and existing services can switch domains.
Will the checker tell me when an address expires?
No. It checks a domain list, not a mailbox lifetime.
Does no match guarantee a permanent inbox?
No. It also says nothing about mailbox existence or permission to send.
