Disposable email checker
Enter a domain or an email address to see whether it belongs to a known throwaway email provider.
Disposable (temporary) email services give out inboxes that vanish after minutes or hours. People use them to dodge sign-up forms, trials and newsletters. Addresses on these domains rarely become customers and often bounce soon after.
When to use it
- You see a suspicious sign-up and want a quick check of the domain.
- You want to know whether a domain belongs to a well-known throwaway provider.
- You are deciding whether to block such addresses on your form.
How to read the result
- "Disposable" means the domain is on our list of common throwaway providers.
- "Not listed" does not prove the address is good: new disposable services appear all the time.
- For a full answer on a specific mailbox, use email verification, which also checks the domain and the mailbox.
Frequently asked questions
Should I block disposable emails at sign-up?
For trials and free tiers, yes. They are rarely real customers. For newsletters, a confirmation email is a fair alternative.
Is the list complete?
No. It covers well-known providers. A verification service keeps a much larger and constantly updated database.
Are aliases such as Gmail plus addresses disposable?
No. They are real mailboxes and valid, just with a tag after the plus sign.
