A little mail. A little responsibility.

These terms apply to the PlateMail app, API, and website operated by William Martin. By using PlateMail, you agree to these terms and the community rules. If you do not agree, do not use the service. The privacy policy explains how information is handled.

You must be at least 13 to use PlateMail. Declare your age band accurately and do not use another account or change your declaration to bypass teen safeguards. If you are under 18, use PlateMail only with permission from a parent or legal guardian where required. Use it only where doing so is permitted, and never interact with it while driving.

Use an email address you control and complete verification when requested. Keep account credentials and verification codes private. Do not impersonate someone, use another person’s account, evade a restriction, or automate abuse.

Other drivers do not see your account email on a note. Authorized moderators can associate activity with your account to investigate reports and enforce these rules. Public anonymity is not a promise that activity cannot be investigated.

Anyone can add a plate, and multiple accounts can follow the same state and plate text. A plate inbox is not private: anyone who adds it can read its available notes and replies, including older mail. Adding a plate does not establish ownership, registration, identity, or a right to speak for its driver.

Removing a plate unsubscribes only your account. It does not remove another person’s access or clear the shared history. Adding it again can restore access to available older mail. The plate preview is illustrative and may not match a specialty or historical design.

A message is limited to 280 characters and can have one mailbox reply. A person following that plate can reply to someone else’s note. That reply is visible with the note in the shared plate inbox.

Messages sent by or delivered to accounts aged 13–17, including replies, require moderator approval before delivery. Review can delay or prevent delivery, including in shared inboxes. Sending and receipt are also subject to service limits, blocking preferences, moderation, and availability; PlateMail does not promise that a particular driver will receive or read a note.

You remain responsible for what you send. You give us permission to store, transmit, display in the shared plate inbox to people who add that plate, and moderate content as needed to operate PlateMail.

Do not send threats, harassment, hateful or sexual content, scams, private identifying information, or repeated unwanted contact. Do not use PlateMail for emergencies, stalking, locating a person, publishing allegations, or coordinating a confrontation. Read the full community rules.

We can review reports, hide or remove content, limit activity, and suspend or ban accounts to protect the service and its users. Automated filters can make mistakes; a filtered word is not approval of a message’s meaning. Attempts to evade blocking, rate limits, verification, or moderation can lead to restrictions.

For a question about a moderation decision, contact support with the relevant details. Do not include passwords, verification codes, or another person’s private information.

PlateMail is provided as available and can change as we improve it. Features may be interrupted, messages may be removed under these rules, and access may be limited for maintenance or abuse prevention. Nothing in these terms limits rights or obligations that cannot lawfully be limited.

PlateMail is not an emergency service, government service, vehicle-registration authority, or substitute for contacting the appropriate authorities when someone is in immediate danger.

You can stop using PlateMail and delete your account from the app. Removing a plate or uninstalling the app is not the same as requesting account deletion.

We may update these terms and will identify the new version by the date on this page. A limited, pseudonymous keyed email hash can remain for 90 days after deletion of a banned account to prevent re-registration with the same email; see the privacy policy. Questions about these terms can be sent to PlateMail support.
