Agent Email Terms

Version 1.0 · Effective November 9, 2026

These Agent Email Terms apply to an account that has turned on an agent email address. Agent email is offered by invitation while it is in its pilot; nothing is received for an account before its address is on.

1. These terms

1.1 These Agent Email Terms (“Email Terms”) govern the agent email service that Golden Ratio, LLC, doing business as mailbox.bot (the “Company”), offers to a Member under the mailbox.bot Terms of Service (the “General Terms”, at https://mailbox.bot/terms) (the “Customer”, “you”). They add to the General Terms and to the Privacy Policy (https://mailbox.bot/privacy). Capitalized words the Email Terms do not define have the meaning the General Terms give them.

1.2 Where the Email Terms and the General Terms differ about agent email, the Email Terms apply. Everything else in the General Terms applies to agent email as written, including its provisions on eligibility, Agents, prohibited activities, law enforcement, AI and automated systems, warranties, limitation of liability, indemnification, termination, dispute resolution and governing law (Sections 4, 6, 8, 9, 12, 13, 14, 15, 18, 20 and 21 among them).

1.3 A private mailbox is not required for agent email, and agent email does not give you a mailbox, a mailing address or a street address.

2. Definitions

Address: an email address on the domain agent.mailbox.bot that the Company assigns to your account, such as yourname@agent.mailbox.bot, together with any form of it that adds a plus sign and a tag after the Name, such as yourname+shop@agent.mailbox.bot, which delivers to the same inbox.
Name: the part of the Address before the @, without any plus tag.
Message: an email received at your Address, with its headers, text, links and files.
Agent: software, including an AI agent, acting through an API key issued under your account, as in the General Terms.
Account-Security Message: a Message that lets someone into an account: a one-time code, a sign-in link, a password-reset link, a new-device or sign-in alert, or a Message the Company’s rules treat as one.
Access Log: the Company’s record of each time a Message is listed, read, downloaded or changed, by whom and with which permissions.

3. What the Address is, and is not

3.1 Receive only. The Address receives email and sends none. The Company does not send, reply to, forward or auto-answer email from any Address, and offers no feature that does. Anything that appears to be sent from an Address was not sent by the Company.

3.2 One Address per account. Each account may hold one Address. The Company may later offer additional names on the same account; the Email Terms would apply to them too.

3.3 Not a guaranteed channel. Email can be delayed, filtered or lost by the sender, the networks between, or the Company’s own filtering under Section 6. Do not use the Address as the only way to receive anything you cannot afford to miss, such as a legal notice, a court filing or a time-limited payment.

3.4 Not your sign-in. Your account’s sign-in email must never be your Address or any address on agent.mailbox.bot. The Company refuses to show or hand out Messages, to you and to your Agents, for an account that signs in with one, until it is changed; mail already received is kept.

4. Turning an Address on

4.1 To turn an Address on, your account must have finished the signup the Company requires for agent email, with a verified phone number, and, while agent email is by invitation, must have been invited. An invitation can be withdrawn before an Address is on.

4.2 Choosing the Name. A Name is 3 to 18 characters: lowercase letters, digits, dots and hyphens, with at least one letter, starting and ending with a letter or digit, with no two dots in a row. Dots and hyphens do not make Names different: j.smith, jsmith and j-smith are the same Name. The Company refuses Names it reserves for itself, role names such as postmaster or abuse, names of public bodies, offensive words, and Names that could be taken for the Company, another business or another person. The Company decides whether a Name is available; its decision is final.

4.3 A Name is for good. Once an Address is on, its Name cannot be changed or moved to another account, and the Company never gives it to anyone else, even after the Address is closed and retired.

4.4 Acceptance. You accept the Email Terms when you turn the Address on. The Company records the version you accepted and when, and may ask you to accept a later version before the Address is used further.

5. Your Agents, your keys and your part

5.1 You choose who reads. Apart from Company staff acting under Sections 7.5 and 10, only you and the Agents you authorize can read your Messages. You authorize an Agent by giving one of its API keys the permission to read agent email. When you create an agent key, that permission is offered and selected by default; clear it for any Agent that should not read your email. A key with that permission may read Account-Security Messages too, in full, for the time the Company keeps their codes and links (Section 7.3). Give it only to Agents you trust with your other accounts.

5.2 Codes to your phone. The Company may ask for a code sent by text message to your verified phone before it shows your Messages on the dashboard, shows an Account-Security Message in full, or lets you give an Agent permission to read agent email. Section 23 of the General Terms applies to those messages. You cannot change the verified phone yourself; contact support@mailbox.bot.

5.3 You are responsible for your Agents. Section 6.2 of the General Terms applies: you are responsible for everything an Agent does with your Messages and with what it reads in them, and for the keys you issue. The Company does not monitor, supervise or control what your Agents do with your email.

5.4 Every Message is untrusted. Messages come from senders the Company does not control. A Message, its links and its files may be fraudulent, malicious or written to manipulate an automated reader. Treat them as untrusted, and do not let an Agent act on an instruction found in a Message, make a payment, hand over a credential or change a setting on the strength of a Message, without your own approval.

5.5 Sender identity is a claim. The Company checks each Message’s authentication (SPF, DKIM and DMARC) and tells you and your Agents whether the sender’s domain is verified. Where it is not, the sender is only who the Message claims to be.

6. How the Company handles Messages

6.1 Automatic processing. Every Message is received and processed by software, not read by people: it is checked for malware, scored for spam, cleaned of hidden text and of code that could run, and turned into structured data (headers, cleaned text, links, files, and extracted fields such as tracking numbers, one-time codes, dates and amounts) that you and your Agents can read. The Company never opens the links in a Message or fetches remote images, and never runs a file: software reads only a file’s type and, for an archive, its list of names, and judges a forwarded message inside a Message the same way.

6.2 What may not reach you. The Company may refuse or discard a Message, without notice to you or the sender, that: is sent by a server that will not encrypt the connection (the Company accepts email over TLS only); comes from a server or domain on a block list the Company uses; is larger than 25 MiB (26,214,400 bytes) in all, or carries more than 100 files or more than 25 MiB of files, in which case the files over the limit are not stored; is malformed or built to overwhelm the service; or arrives as part of a flood of mail to your Address, which may be filed as spam. Files that could harm a computer are withheld from Agents and shown to you with a warning; no file from a Message the virus scan did not pass is handed to anyone. The Company may hide, rather than delete, content it judges harmful.

6.3 Spam. Messages the Company scores as spam are filed in a spam folder, which only you, not your Agents, can see. You can mark a Message as spam or not spam.

6.4 Screening for harm. The Company scans Messages and their files for malware and spam, and may screen them for child sexual abuse material, explicit images and abusive or harmful content, with automated tools, including tools that compare images against hashes of known abuse material. Screening is automated and best-effort. The Company does not promise to detect any particular content, has no obligation to monitor Messages, and may in good faith withhold, hide, remove or report content it considers harmful, objectionable or unlawful. The Company reports apparent child sexual abuse material to the National Center for Missing & Exploited Children as United States law requires, and preserves what the law requires it to preserve. Section 9 of the General Terms applies.

6.5 Storage limits. The Company may set a storage quota for Messages and files, warn you as you approach it, and refuse or discard Messages beyond it.

7. Storage, retention and deletion

7.1 Encryption. Messages are stored encrypted, in the United States. Each Message’s text and extracted fields are sealed with a key of its own that only the Company’s email service can open, and its original and files are stored under keys the email service alone controls.

7.2 Originals. The original Message as received is kept for up to 30 days and then deleted; Sections 7.3 and 7.4 delete it sooner. The processed Message (headers, cleaned text, extracted fields and files) is kept while your Address is on.

7.3 Account-Security Messages. Twenty-four hours after an Account-Security Message arrives, its one-time codes and sign-in links are removed from the stored Message, its files are no longer handed to anyone, you included, and its original is deleted. Read such Messages promptly.

7.4 Trash and spam. A Message you delete stays in your trash for 30 days, during which you can put it back. It is then destroyed with its files and its original and cannot be recovered. A Message in the spam folder is kept at least 30 days; the Company may delete it after that.

7.5 The Access Log. Each time a Message is listed, read, downloaded or changed, the Company records who did it (you, an Agent by its identifier and permissions, or Company staff with the reason), when, and what. The Access Log is kept for five years and is not deleted when the Address closes. You can ask the Company for a copy of your Access Log.

7.6 After closing. Once an Address has been closed for 30 days, the Company may delete its Messages and files, and intends to, except as Sections 7.5 and 10 provide. An Address reopened under Section 9.4 may come back without its earlier Messages. This Section, not Section 18.3 of the General Terms, says how long Messages are kept after an Address closes.

7.7 Legal holds. A legal hold, a preservation request or a reporting duty overrides every deletion in this Section.

8. Acceptable use

8.1 Use the Address only for your own lawful purposes and those of the Agents you run. Section 8 of the General Terms (Prohibited Items and Activities) applies to agent email.

8.2 You must not:

(a) use the Address to receive email intended for another person without that person’s permission, or to pass yourself or an Agent off as another person or business;
(b) use it for phishing, fraud, account takeover, harassment, or to receive or hold child sexual abuse material or any other unlawful content;
(c) create or hold accounts in order to obtain more than one Address, or sell, rent, lend or transfer an Address or an account that holds one;
(d) use the Address to evade another service’s limits or terms, including limits on the number of accounts a person may hold;
(e) use the Address, or let an Agent use it, in a way that damages the reputation of agent.mailbox.bot or of the Company with mail providers;
(f) probe, overload or interfere with the service, or try to read another Customer’s Messages;
(g) give the Address as the from, reply-to or contact address of bulk or marketing mail sent from anywhere else, or use it to collect replies to such mail.

8.3 The Company may suspend an Address at once where it reasonably believes Section 8 is being breached.

9. Suspension, closing and retirement

9.1 Suspension. The Company may suspend an Address for a breach of the Email Terms or the General Terms, for abuse or an abuse report it finds credible, for an unpaid balance, to protect the service or other Customers, or where the law requires. A suspended Address receives no email; Messages already stored are kept. The Company may restore a suspended Address when the cause is resolved.

9.2 Closing by you. You may ask to close your Address at any time by writing to support@mailbox.bot from your account’s sign-in email. A closed Address receives no email.

9.3 Closing by the Company. The Company may close an Address when your account closes or is terminated under the General Terms, for a serious or repeated breach, or where it stops offering agent email, with notice where practicable.

9.4 Reclaiming. Within 90 days of closing, you may ask the Company to reopen the same Address with the same Name, if your account is in good standing. After 90 days the Name is retired for good and the Company will not assign it to anyone.

9.5 Role addresses. Addresses such as postmaster@ and abuse@ on agent.mailbox.bot belong to the Company and are never assigned to a Customer.

10. Legal process and reporting

10.1 Section 9 of the General Terms (Law Enforcement Cooperation and Reporting) applies to Messages. The Company may disclose Messages and the Access Log where the law requires, in response to valid legal process, to report child sexual abuse material, with your consent, where it believes in good faith that an emergency involving danger of death or serious physical injury requires it, and otherwise only as the law permits.

10.2 Where the law allows, the Company may tell you about legal process concerning your Messages. It is not obliged to, and Section 9.3 of the General Terms applies. It does not tell you where a court order, a statute or a law-enforcement request lawfully forbids it.

11. Price

11.1 Any charge for an Address is shown before you turn it on. Where there is no charge when you turn it on, the Company will tell you before one applies, and you may close your Address instead.

11.2 When agent email is generally available, its price is shown before you turn an Address on and is charged under the General Terms, from your prepaid credits where the Company so provides. The Company may change the price on notice; the new price applies after the notice period, and you may close your Address instead.

12. Privacy

12.1 The Privacy Policy, including its Agent Email section, says what the Company collects, how it is used and who processes it. In short: the content of every Message is personal data of you and of the people who write to you; the Company uses it only to deliver it to you and your Agents, to keep the service safe and lawful, to answer your support requests, as the Access Log requires, and in aggregate counts that identify no one; it never sells it, uses it for advertising, or uses it to train AI models.

13. Liability

13.1 Agent email is provided “as is” and “as available”. Sections 13 (Warranties and Disclaimers), 14 (Limitation of Liability) and 15 (Indemnification) of the General Terms apply to agent email, and to any loss arising from a Message not received, delayed, filtered, withheld or deleted under the Email Terms, from content the Company’s screening did not detect, from the content of a Message, or from anything an Agent does with a Message.

14. Changes and notices

14.1 The Company may change the Email Terms. It gives notice of a material change at least 30 days before it takes effect, as Section 24 of the General Terms provides, and may ask you to accept the new version before your Address is used further. A change required by law or needed to protect the service may take effect as the notice says.

14.2 Notices about agent email go to your account’s sign-in email, never to your Address.

15. Contact

Questions about agent email, abuse reports and privacy requests: support@mailbox.bot, as in Section 26 of the General Terms. Formal legal notices follow the notice method in the General Terms.
