1. Core Rule
Use MailSub.Site only for lawful, permission-based, accurately identified email. If a campaign would reasonably cause recipients, mailbox providers, or regulators to view it as spam, deception, or abuse, it is not allowed.
2. Consent and Recipient Lists
You may send only to recipients who have a valid basis to receive the message.
- Allowed: direct opt-in, double opt-in, existing lawful basis where permitted by law, or transactional and relationship messages that fit the law and the message type.
- Not allowed: purchased, rented, scraped, harvested, appended, guessed, brokered, auto-enrolled, or copied lists from third parties without valid transferable permission.
- Not allowed: signup forms using pre-checked consent boxes for marketing.
- Not allowed: sending to old or dormant lists that you cannot reasonably validate.
3. Proof of Permission
You must keep sufficient records to show how each recipient was added to your list. Those records should include, where relevant, signup date, signup source, form language or notice shown at signup, and any confirmation event.
4. Accurate Identity and Content
- Do not use deceptive, misleading, or forged headers, display names, subject lines, or sender identities.
- Do not impersonate another person, business, or domain without authority.
- Do not disguise marketing as personal, conversational, or transactional email.
- Do not hide the sender or route mail in ways meant to evade filtering, reputation systems, or enforcement.
5. Unsubscribes and Suppression
- Every marketing email must contain a clear unsubscribe method.
- Where required by mailbox-provider rules or applicable law, messages must support one-click unsubscribe.
- Unsubscribe requests must be honored promptly, and in any event within the stricter of applicable law, mailbox-provider requirements, or our internal safety rules.
- Recipients who unsubscribe, hard bounce, or complain must be suppressed from future campaigns unless and until they validly re-subscribe.
6. Technical Sending Standards
To send at scale, you may be required to implement SPF, DKIM, DMARC, valid forward and reverse DNS, secure transport, and standards-compliant message formatting. We may require additional operational controls such as rate limits, dedicated domains, or complaint-loop enrollment.
7. Spam Complaint Thresholds
MailSub.Site monitors complaint counts and complaint rates because they are essential to protecting deliverability. Unless a stricter standard is communicated for a specific account, the default complaint framework is:
- 0.10% or higher: warning, closer review, or remediation request.
- 0.20% or higher: temporary sending limits, campaign review, or mandatory list cleanup.
- 0.30% or higher: immediate pause, suspension, or termination review.
We may act sooner when complaint spikes, abuse patterns, or mailbox provider signals show elevated risk even if the numeric threshold has not yet been crossed.
8. Bounce and Hygiene Expectations
- Repeated hard bounces, invalid addresses, or clear list-decay signals may trigger review or sending limits.
- You must remove or suppress addresses that repeatedly soft bounce if continued sending is no longer reasonable.
- We may require list reconfirmation or hygiene work before restoring full sending access.
9. Prohibited Content and Conduct
- Spam, phishing, malware, credential theft, or malicious attachments.
- Fraudulent offers, counterfeit goods, illegal products, or unlawful financial schemes.
- Identity abuse, domain spoofing, or unauthorized relay activity.
- Content intended to evade mailbox filtering, reputation systems, or complaint tracking.
- Use of the platform to test stolen lists, enumerate inboxes, or probe deliverability of unauthorized recipient data.
10. Monitoring and Review
We may review list source information, complaint and bounce metrics, authentication status, sample message content, unsubscribe handling, and related operational data to investigate abuse or preserve network health. This review is limited to what is reasonably necessary to run the service and enforce this policy.
11. Enforcement
We may take any of the following actions:
- warning or request for clarification;
- requirement to provide consent evidence or remediation steps;
- campaign hold, throttling, or account-level sending limits;
- suppression requirements or mandatory list cleanup;
- temporary suspension; or
- immediate termination for severe or repeated violations.
Severe violations include phishing, malware, forged identities, deliberate evasion of unsubscribe requirements, or obvious use of non-permission-based lists.
12. Appeals
If we pause or suspend an account, you may contact [support email] to request review. We may ask for list source details, campaign samples, authentication records, or other evidence before restoring service.
