Last updated: March 21, 2026

1. Purpose

This Acceptable Use Policy ("AUP") defines the acceptable and prohibited uses of Huppmail's email delivery service. This AUP is incorporated into and forms part of the Huppmail Terms of Service. All users of Huppmail must comply with this policy at all times.

Huppmail maintains a strict anti-spam stance to protect the deliverability and reputation of all users on the platform. Violations of this policy harm every user's ability to reach inboxes reliably.

2. Prohibited Content

You may not use Huppmail to send, distribute, or facilitate the delivery of:

  • Spam: Unsolicited bulk email, including commercial messages sent to recipients who have not opted in to receive them.
  • Phishing: Messages designed to deceive recipients into revealing personal information, credentials, or financial data, or that impersonate another person or organization.
  • Malware: Messages containing or linking to viruses, trojans, ransomware, spyware, or any other malicious software.
  • Illegal content: Any content that violates applicable local, national, or international laws or regulations.
  • Harmful content directed at minors: Adult or sexually explicit content sent to or targeting individuals under the age of 18.
  • Violence and hate: Content that promotes, incites, or glorifies violence, terrorism, or hatred against individuals or groups based on race, ethnicity, religion, gender, sexual orientation, disability, or any other protected characteristic.

3. Prohibited Practices

The following practices are strictly prohibited when using Huppmail:

  • Purchased or harvested lists: Sending emails to recipients whose addresses were purchased, rented, scraped, or harvested from third-party sources. All recipients must have been collected through your own direct relationship.
  • Sending without valid consent: Sending emails to recipients without valid opt-in consent. You must have verifiable evidence of consent for each recipient on your mailing list.
  • Ignoring unsubscribe requests: Failing to honor unsubscribe or opt-out requests within 48 hours of receipt. All marketing emails must include a functional unsubscribe mechanism.
  • Falsifying sender information: Forging, manipulating, or misrepresenting email headers, sender addresses, or reply-to addresses to disguise the origin of messages.
  • Undisclosed third-party relaying: Using the service to relay or send emails on behalf of undisclosed third parties without transparent identification of the actual sender.
  • Circumventing limits: Attempting to circumvent sending limits, rate limiting, throttling, or any other usage restrictions through technical means, including creating multiple accounts for this purpose.
  • Email bombing and harassment: Using the service to send large volumes of emails to a single recipient or a small group of recipients with the intent to disrupt, harass, or overwhelm their email systems.

4. Compliance Requirements

You are responsible for ensuring that your use of Huppmail complies with all applicable laws and regulations, including but not limited to:

  • CAN-SPAM Act (United States) — requirements for commercial email, including identification, opt-out mechanisms, and truthful headers.
  • General Data Protection Regulation (GDPR) (European Union) — requirements for processing personal data and obtaining valid consent.
  • Canada's Anti-Spam Legislation (CASL) — requirements for express or implied consent and identification requirements.
  • Any other applicable anti-spam, data protection, or electronic communications laws in the jurisdictions where your recipients are located.

5. Monitoring

Huppmail monitors sending patterns and key metrics to maintain platform health and protect all users. We track:

  • Bounce rates: Accounts with a bounce rate exceeding 5% may be flagged for review and subject to sending restrictions.
  • Complaint rates: Accounts with a spam complaint rate exceeding 0.1% may be flagged for review and subject to sending restrictions.
  • Sending patterns: Unusual spikes in volume, sudden changes in recipient domains, or other anomalous behavior may trigger automated review.

Flagged accounts will be notified and given the opportunity to address the issue. Persistent high bounce or complaint rates may result in enforcement action as described below.

6. Enforcement

Violations of this AUP are handled through a graduated enforcement process:

  1. Warning: For first-time or minor violations, we will issue a written warning with specific details of the violation and required corrective actions.
  2. Temporary suspension: For repeated violations or failure to address a warning, your sending privileges may be temporarily suspended while the issue is investigated and resolved.
  3. Permanent ban: For continued violations after suspension, or for users who demonstrate a pattern of non-compliance, the account will be permanently terminated.

Immediate termination: Severe violations, including but not limited to phishing, malware distribution, and illegal activity, will result in immediate account termination without prior warning. We reserve the right to report such activity to the relevant authorities.

7. Reporting Abuse

Include any relevant email headers, message content, and details of the suspected violation. We investigate all reports promptly.
