Terms of Service

1. Acceptance of Terms

mail.cx is operated by SICHUAN HAONI E-COMMERCE CO., LTD. By accessing or using mail.cx, you agree to be bound by these Terms of Service. If you do not agree to these terms, you must not access or use the service.

2. Service Description

mail.cx provides web-based inbox services, email receiving functionality, and related developer features for testing, integration, and email workflow use cases. The service is receive-only and does not provide email sending functionality. Inboxes and related message data may expire automatically after a limited period of time. Pro subscribers get additional features, including custom domains, dedicated system domains, API access, and extended retention. Free accounts do not include these features.

3. Accounts

You may use certain parts of the service without creating an account, where such access is made available. Some features require registration with a valid email address and password. You are responsible for maintaining the confidentiality of your login credentials and for all activities that occur under your account. We reserve the right to suspend, restrict, or disable accounts that violate these Terms of Service or otherwise pose a risk to the service or its users.

4. Acceptable Use

You agree not to use mail.cx for any unlawful, harmful, abusive, or fraudulent purpose. Prohibited uses include, but are not limited to:

• Sending, distributing, or supporting spam, phishing, malware, or other malicious content
• Fraudulent activity, impersonation, or identity theft
• Unauthorized automated registration or abusive activity on third-party services
• Violating applicable laws, regulations, or third-party rights
• Attempting to interfere with, disrupt, or attack the service infrastructure, or misusing the API, domains, or inboxes in a manner that harms the platform or other users

5. API Usage

API access is subject to usage limits, rate limits, and plan-specific restrictions. Exceeding those limits may result in throttling, temporary suspension, or access restrictions. You are responsible for keeping your API credentials secure. API tokens must not be exposed publicly or shared in an unauthorized manner. We may suspend or revoke API access in cases of abuse, misuse, security risk, or violations of these terms.

6. Abuse & Rate Limits

To protect the service and all users, mail.cx enforces rate limits and automated abuse detection. By using the service, you acknowledge and agree to the following:

• Mailbox creation, API calls, and other operations are subject to per-IP, per-account, and global rate limits. These limits vary by plan — Pro users enjoy higher quotas.
• Automated systems monitor for abnormal patterns, including excessive authentication failures, repeated invalid requests, and high-frequency operations. Accounts or IP addresses that trigger these thresholds may be temporarily or permanently banned without prior notice.
• Attempts to circumvent rate limits — such as rotating IPs, forging client identifiers, or scripting around throttling — are considered a violation of these Terms and may result in immediate suspension.
• Bans may be applied automatically or manually by our team. Banned users will receive an appropriate HTTP error response. We are not obligated to disclose specific thresholds or detection criteria.
• If you believe a ban was applied in error, contact us at service@spamcage.com with your account details.

7. Service Availability

mail.cx is provided on an "as is" and "as available" basis. While we aim to provide a reliable service, we do not guarantee uninterrupted availability, error-free operation, or permanent access to any feature. We may modify, restrict, suspend, or discontinue any part of the service at any time, with or without notice.

8. Data Retention and Limitation of Liability

mail.cx is designed for short-term developer testing and email workflow usage. Messages, inboxes, and related data may expire automatically and may be permanently deleted after expiration. We do not guarantee message retention, recovery, or long-term storage. You should not rely on mail.cx for critical, sensitive, or business-essential communications. To the fullest extent permitted by law, mail.cx and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, emails, business, revenue, or opportunity arising out of or related to your use of, or inability to use, the service.

9. Termination

We reserve the right to suspend, restrict, or terminate access to the service, in whole or in part, at our sole discretion, with or without notice, if we believe your use violates these Terms of Service, creates legal or security risk, or may harm the service, users, or third parties.

10. Refund Policy

mail.cx offers a single paid plan, Pro, billed at $9.9 per year. Our order process is conducted by our online reseller Paddle.com (Paddle.com Market Limited or the relevant Paddle entity). Paddle.com is the Merchant of Record for all our orders, and Paddle's Buyer Terms and Refund Policy apply to your order in addition to these terms. Paddle provides all customer service inquiries and handles returns. We offer a 15-day money-back guarantee on your first Pro subscription payment: if the service is not right for you, request a refund within 15 days of that payment and we will refund it in full. The guarantee covers the initial subscription payment only — automatic renewal payments are not refundable, and no refund is given for the unused part of a period you have already paid for. Nothing in this section limits any statutory cancellation, withdrawal, or refund rights you have under the consumer law that applies to you; where those rights are greater, they apply.

How to request a refund

Request a refund through Paddle using the support link in your payment receipt or the billing page linked from your dashboard, or email us at service@spamcage.com with the email address on your account and your Paddle receipt ID. We review every request and aim to respond within 3 business days. Approved refunds are issued by Paddle back to the original payment method; the time it takes to appear on your statement depends on your bank or card issuer.

What happens after a refund

• Your account returns to the Free plan as soon as the refund is processed, and new mail is kept for 1 hour instead of 72 hours.
• API keys stop working immediately, because API access on api.mail.cx is a Pro feature. Your keys are not deleted, but they cannot be used until you subscribe again.
• Custom domains stop receiving mail and dedicated system domains are no longer available, because both are Pro features. Your domain configuration is kept, so mail delivery resumes if you subscribe again.
• Mail already stored in your inboxes is not deleted early; it expires under the retention it was received with.

Cancellation

You can cancel at any time on the Paddle billing page linked from your dashboard — cancellation is handled by Paddle, not by us, and the same page is where you update your payment card. Pro stays active until the end of the period you have already paid for and is not renewed after that. Cancelling on its own does not produce a refund of the current period. If a renewal payment fails, the account is downgraded to the Free plan, with the same effects listed above.
