# `mail_drop_address_with_free_email_provider`: a mail-drop address with a free email provider

The postal address is a commercial mail-receiving agency or mailbox rental, and the email is at a free consumer provider.

- Appears in: `flag`
- Billing: Free. The consistency analysis is arithmetic over answers already paid for and never costs a credit of its own.

`is_mail_drop` comes from the mail-drop lists installed for that country, and answers null where none is installed — silence, never false.

Mail drops are a legitimate service used by travellers, small businesses and people without a fixed address. The flag names a combination, not wrongdoing.

**What to do.** Relevant where you need to reach someone at a residential or registered business address; otherwise ignore it.
