Terms of Service

1. Acceptance of Terms

These Terms govern your use of Mail.cx, an independently operated email-receiving service. In these Terms, "we", "us" and "our" refer to the operator of Mail.cx. By using the Service, you agree to these Terms. For any questions about the Service, billing or legal matters, contact . 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 users 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 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. Billing, Renewal and Refunds

mail.cx offers one paid plan, Pro, sold as a one-time payment of $9.9 for one year of access. It does not renew automatically, and nothing is charged again unless you choose to buy another year. Buying another year while Pro is active adds one year to your current end date.

Our order process is conducted by our online reseller Creem (Armitage Labs OÜ, registry code 16977866, Rotermanni 14, Tallinn 10111, Estonia). Creem is the Merchant of Record for all our orders: it processes your payment, issues your invoice, and calculates and collects any applicable sales tax or VAT, which is shown at checkout. The charge appears on your card statement as CREEM.IO*. Creem's Buyer Terms apply to your purchase in addition to these terms.

Customer service for your purchase — questions, invoices and refund requests — is provided by us at . We respond within 3 business days.

15-day money-back guarantee

Your first Pro purchase is covered by a 15-day money-back guarantee: request a refund within 15 days of that payment and it is refunded in full, with no reason required. Later purchases (such as an additional year) and renewal payments of subscriptions bought earlier are not refundable, and no refund is given for the unused part of a period you have already paid for. Creem may also refund a payment where the law or card-network rules require it, for duplicate payments or technical errors, and at its own discretion within 60 days of purchase. Nothing in this section limits the statutory rights you have under the consumer law that applies to you, such as the right of withdrawal of consumers in the European Union; where those rights are greater, they apply. Full details are in our Refund Policy.

How to request a refund

Email from the email address on your account and include the Creem order ID from your receipt. Refunds are handled exclusively by Creem and returned to your original payment method, usually within 5–10 business days depending on your bank or card issuer. If we have not replied within 7 days, you can contact Creem support at creem.io/contact.

What happens after a refund

• The year of Pro bought with the refunded payment ends as soon as the refund is processed. Unless another year you bought is still running, your account returns to the Free plan 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 buy Pro 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 buy Pro again.
• Mail already stored in your inboxes is not deleted early; it expires under the retention it was received with.

No automatic renewal

A one-time purchase ends by itself at the end of its year; there is nothing to cancel, and your account then returns to the Free plan unless you have bought another year. Your dashboard shows the date Pro runs until, and "Orders & invoices" opens the billing portal — also reachable at creem.io/my-orders/login with the email address you paid with — where you can download invoices. If you bought Pro earlier as an automatically renewing yearly subscription, it keeps renewing until you cancel it, which you can do at any time from your dashboard: the renewal stops and Pro stays active until the end of the period you have already paid for, except that a cancellation made in the Creem billing portal takes effect immediately. If a renewal payment of such a subscription fails, Pro features are paused while the payment is retried, and the subscription ends if the payment cannot be collected.
