Disposable email domain check

Enter a domain or an address to see whether it belongs to a known throwaway email service.

disposable · mailcut

The check reads public DNS records only. No email is sent and the address is not stored.

Throwaway services hand out inboxes that disappear after minutes or hours. People use them to download something, test a trial or avoid a newsletter. The addresses rarely turn into customers, and many stop working soon after they are collected.

Good uses

  • A sign-up looks suspicious and you want a quick look at its domain.
  • You want to see if a domain is one of the well-known throwaway providers.
  • You are deciding whether your form should refuse such addresses.

What the answer means

  • "Disposable" means the domain is on our list of common throwaway services.
  • "Not listed" is not a guarantee: new services appear all the time.
  • To judge a specific address, run a full verification, which also checks the domain and the mailbox.

Frequently asked questions

Should I block disposable addresses?

On free trials and downloads, usually yes. For newsletters, a confirmation email is a gentler choice.

Is your list complete?

No list can be. It covers well-known services and is updated, but a verification check is more reliable than a lookup.

Do disposable addresses cost credits to verify?

They are checked like any other address and are labelled Disposable in the report.
