Acceptable Use Policy

One rule above all: only email people who asked to hear from you. Everything below is the detail.

Last updated — May 22, 2026

This Acceptable Use Policy (the "AUP") governs your use of Cyber Mail 9000 (the "Service"), operated by McPherson Enterprises, LLC, doing business as Cyber Mail 9000 ("we", "us"). It is part of, and incorporated by reference into, our Terms of Service. By using the Service you agree to follow this AUP. If you do not agree, do not use the Service.

We send email on behalf of our customers. The trust we have with mailbox providers — Gmail, Outlook, Yahoo, Apple, and others — is shared across everyone who sends through us. One bad actor can damage deliverability for every other customer. This policy is how we keep that from happening. We enforce it strictly and without apology.

1. Consent is the only acceptable basis for sending

You may only send email through the Service to recipients who have given you direct, verifiable, and recent permission to email them. Permission must come from the recipient themselves — for example, by subscribing through your own signup form, creating an account on your site, enrolling in your course, or opting in to receive your content.

You must be able to document, for any recipient, how and when they opted in. We may ask.

2. Prohibited lists — zero tolerance

You may not send email to addresses that were:

  • Purchased, rented, or leased from any third party.
  • Scraped, harvested, or crawled from websites, social media, directories, or any other source.
  • Collected by a third party and transferred to you, including co-registration, "appended" lists, and lead-broker lists.
  • Obtained from any source where the recipient did not knowingly opt in to receive email from you specifically.
  • Compiled by guessing, generating, or appending addresses to names or domains.

The fact that an address appears on a list you legally possess does not mean you have consent to email it. Consent is not transferable between senders.

3. Prohibited sending practices

You may not use the Service to:

  • Send unsolicited email, cold outreach, or "spray and pray" campaigns of any kind.
  • Falsify, forge, or obscure the sender, the From, Reply-To, or routing information, or use a subject line that misrepresents the content of the message.
  • Send to addresses harvested for the purpose of evading spam filters or spam traps.
  • Mail addresses that have unsubscribed, hard-bounced, or filed a spam complaint against you.
  • Continue mailing a list that consistently generates high bounce or complaint rates (see Section 8).
  • Relay email through the Service for a third party who has not agreed to this AUP.
  • Operate the Service as a sending engine for another email platform, or resell sending capacity, without our written permission.

4. Prohibited content

You may not use the Service to send or promote:

  • Anything illegal under applicable law, or that facilitates illegal activity.
  • Phishing, credential harvesting, malware, ransomware, spyware, viruses, or any deceptive content designed to defraud or compromise the recipient.
  • Content that infringes another party's intellectual property or privacy rights.
  • Hateful, harassing, threatening, or defamatory content, or content that incites violence.
  • Sexually explicit material, or any content harmful to minors.
  • Deceptive, fraudulent, or "get rich quick" schemes, pyramid or multi-level marketing recruitment, and chain messages.
  • Content that violates the export, sanctions, or trade-control laws of any jurisdiction.

5. Restricted content

Some content is legal but carries elevated deliverability and abuse risk. The following categories are permitted only with prior written approval from us, and may be subject to additional monitoring or volume limits: cryptocurrency, digital assets, and trading; gambling and betting; pharmaceuticals, nutritional supplements, and CBD; debt relief, credit repair, and payday lending; firearms; and adult-oriented (but lawful) products. If you are unsure whether your content qualifies, ask us before sending.

6. Required elements in every email

Every message you send through the Service must:

  • Accurately identify you as the sender in the From name and address.
  • Use a subject line that honestly reflects the content of the message.
  • Include a clear, working unsubscribe link, and the one-click unsubscribe headers the Service adds automatically (RFC 8058).
  • Include a valid physical postal mailing address for your business, as required by the U.S. CAN-SPAM Act and similar laws.
  • Comply with all applicable email and privacy laws, including the CAN-SPAM Act (U.S.), CASL (Canada), the GDPR and ePrivacy rules (EU/UK), and any others that apply to you or your recipients.

7. Unsubscribes

Unsubscribe and opt-out requests must be honored promptly and permanently. The Service processes one-click unsubscribes immediately and automatically. You may not require a recipient to log in, pay a fee, provide information beyond an email address, or take any other step to opt out. You may not re-add or re-import an address that has unsubscribed.

8. Bounce and complaint thresholds

High bounce and complaint rates signal poor list hygiene and threaten deliverability for every customer. You are expected to keep your hard bounce rate below 5% and your spam complaint rate below 0.1% — the thresholds enforced by our upstream email infrastructure. The Service automatically suppresses addresses that hard-bounce or file a complaint, and they may never be emailed again. If your rates approach or exceed these thresholds, we may pause your sending without notice while we investigate.

9. Domain authentication

Managed Sending customers must verify their own sending domain with DKIM, SPF, and DMARC before the Service will deliver any mail on their behalf. You may not send from a domain you do not own or control. Sending is blocked until verification is complete.

10. Security and system integrity

You may not:

  • Probe, scan, or test the vulnerability of the Service or circumvent its security.
  • Interfere with or disrupt the Service, its infrastructure, or other customers' use of it.
  • Access the Service or its data through any means other than our published interfaces.
  • Use the Service to gain unauthorized access to any system, account, or data.

11. Monitoring and enforcement

We monitor sending activity, bounce and complaint rates, and abuse reports. We do not routinely read the content of your messages, but we may inspect content when investigating a suspected violation of this AUP.

If we believe you have violated this AUP, we may, at our sole discretion and with or without prior notice, depending on severity:

  • Issue a warning and request that you correct the problem.
  • Throttle, pause, or suspend your sending — for one brand or your entire account.
  • Remove offending content or lists.
  • Terminate your account under the Terms of Service.
  • Report illegal activity to law enforcement.

Because shared sending reputation is involved, we will act immediately and pause sending first when an active threat to deliverability is present, and investigate afterward. Pausing sending for an AUP violation does not entitle you to a refund of fees or sending credits.

12. Reporting abuse

If you received an unwanted email sent through the Service, or believe a customer is violating this AUP, report it to abuse@cybermail9000.com. Please include the full message with headers where possible. We investigate every report.

13. Changes to this policy

We may update this AUP as laws, mailbox-provider requirements, and abuse patterns evolve. Material changes will be posted on this page with a new "Last updated" date. Continued use of the Service after a change means you accept the revised AUP.
