Frequently Asked Questions

Can I check only whether an address is disposable?

Yes. A separate disposable-email check reports that flag without requesting the full validation result.

Does a free-provider address mean the address is invalid?

The free-provider flag identifies the provider type. Read the other validation signals to assess the address.

Does this connection upload a mailing list for bulk verification?

The available checks accept one email address per call, with no mailing-list upload operation.
