Mail Policy – Welcome to Nan Cloud

Mail Policy


  1. General Mail Usage

Our email service is intended for lawful and legitimate purposes only. Customers are responsible for ensuring that their use of our email services complies with all applicable laws, regulations, and this Mail Policy. Prohibited activities include, but are not limited to, sending unsolicited bulk or commercial messages (spam), phishing, email spoofing, or engaging in any activities that may compromise the security or integrity of our email servers.

  1. Mailing Lists

Customers who operate mailing lists must follow these guidelines:

a) Obtain explicit consent from all recipients before adding them to the mailing list. This can be done through a confirmed opt-in process, such as sending an email with a confirmation link to the recipient’s address.

b) Provide an easy and transparent method for recipients to unsubscribe from the mailing list. Unsubscribe requests must be honored promptly.

c) Ensure that mailing list content is relevant, lawful, and does not violate our Acceptable Use Policy or any applicable laws and regulations.

d) Regularly update and maintain the mailing list to remove invalid or inactive email addresses, which may help reduce bounce rates and improve overall deliverability.

  1. Mail Sending Limits

Our servers limit outgoing emails to 500 messages per hour for each domain. Any emails sent over this limit will bounce back and will not be delivered. Customers are responsible for monitoring their email usage and ensuring that they do not exceed the hourly limit.

  1. Penalties for Policy Violations

Violations of this Mail Policy may result in immediate suspension or termination of your account, without prior notice. We also reserve the right to cooperate with law enforcement agencies in the investigation of any suspected illegal activities, including the provision of customer information as required by law or court order.

  1. Changes to the Policy

We reserve the right to modify or replace this Mail Policy at any time, at our sole discretion. We encourage you to periodically review this Policy to stay informed of any changes. Your continued use of our services after any changes to this Policy constitutes your acceptance of the updated terms.

Any mailing list MUST comply with all guidelines set forth by the United States. These can be found at
