Effective Date: Feb 03, 2026

This Acceptable Use Policy ("AUP") governs your use of UNMTA LLC's email infrastructure services ("Services"). By using our Services, you agree to comply with this AUP. Violation of this AUP may result in suspension or termination of your account.

1. Permitted Use

UNMTA provides dedicated email infrastructure for legitimate, permission-based email communications. You may use our Services to send:

Transactional emails (order confirmations, password resets, account notifications)
Marketing emails to recipients who have provided consent
Newsletters and content updates to opted-in subscribers
Business communications where a legitimate relationship exists

2. Prohibited Content

You may not use our Services to send emails containing or promoting:

Illegal content — Any material that violates applicable laws or regulations
Phishing or fraud — Deceptive messages designed to obtain sensitive information or defraud recipients
Malware or harmful code — Viruses, trojans, ransomware, or links to malicious software
Scams — Advance-fee fraud, pyramid schemes, fraudulent investment opportunities, or deceptive offers
Affiliate marketing — Emails primarily promoting affiliate links or offers, regardless of list quality
Impersonation — Messages falsely representing the sender's identity or organizational affiliation
Harassment or threats — Content intended to harass, threaten, or intimidate recipients

Legal content in regulated industries (including adult, cannabis, gambling, cryptocurrency, and political communications) is permitted provided you comply with all applicable laws, maintain proper recipient consent, and adhere to all other provisions of this AUP.

3.1 Permission Required

All recipients must have provided consent to receive email from you. Acceptable forms of consent include:

Single opt-in — Recipient actively submitted their email address through a signup form, registration process, or explicit request
Confirmed opt-in (double opt-in) — Recipient confirmed their subscription via a verification email
Transactional relationship — Recipient has an existing business relationship and the email relates to that relationship

3.2 Prohibited List Sources

The following list sources are strictly prohibited:

Purchased or rented email lists
Scraped, harvested, or crawled email addresses
Lists obtained through co-registration where your specific communications were not disclosed
Appended email addresses (adding emails to existing contact records via third-party data)
Lists shared or transferred from other organizations without explicit recipient consent for your communications
Email addresses collected through deceptive means or without the recipient's knowledge

3.3 List Hygiene

You are responsible for maintaining clean, engaged email lists. We recommend:

Removing hard bounces immediately
Re-confirming consent for lists that have not been mailed in over 12 months
Implementing engagement-based list management to remove chronically unengaged subscribers
Honoring all unsubscribe requests within 10 business days (or shorter if required by applicable law)

4. Sending Requirements

4.1 Message Content Standards

All emails sent through UNMTA must:

Clearly identify you as the sender
Include a valid physical mailing address
Provide a functioning unsubscribe mechanism for commercial emails
Use accurate, non-deceptive subject lines
Comply with CAN-SPAM, CASL, GDPR, and all other applicable email regulations

4.2 Authentication

You must properly configure email authentication for all sending domains:

DKIM signing (configured through your UNMTA control panel)
We recommend implementing DMARC policies to protect your domain reputation

4.3 Third-Party Sending

Sending email on behalf of third parties (ESP, platform, or agency use cases) is permitted exclusively on our Platform plan. If you operate a platform where your customers send email through your UNMTA infrastructure:

You are responsible for ensuring your customers comply with this AUP
Your customers must adhere to the same consent and list requirements as direct UNMTA senders
You must have a contractual relationship with your customers that obligates them to follow email best practices
You remain liable for all email sent through your account, regardless of originating customer

5. Complaint Thresholds and Monitoring

5.1 Complaint Rate Standards

We monitor spam complaint rates across major mailbox providers. The following thresholds apply:

Below 0.1% — Healthy; no action required
0.1% to 0.3% — Warning; you may be contacted to discuss remediation
Above 0.3% — Suspension; sending may be paused until the issue is resolved

Complaint rates are calculated as spam complaints divided by emails delivered, measured on a rolling basis per mailbox provider.

5.2 Bounce Rate Standards

Excessive bounce rates indicate list quality issues:

Hard bounce rates above 5% may trigger a review of your list acquisition practices
Repeated high bounce rates may result in sending restrictions

5.3 Response Requirements

When UNMTA contacts you regarding an abuse complaint or requests information about your sending practices:

You must respond within 24 hours
You must provide requested documentation (consent records, list sources, sending context)
Failure to respond promptly may result in precautionary suspension

6. Enforcement

6.1 Graduated Response

For most violations, we follow a graduated enforcement approach:

Warning — Notification of the issue with required corrective action
Temporary suspension — Sending paused until the issue is resolved
Permanent termination — Account closed for repeated or unresolved violations

We reserve discretion to skip steps based on severity and your responsiveness.

6.2 Immediate Termination

The following violations result in immediate account termination without prior warning:

Phishing, fraud, or scam emails
Distribution of malware or harmful code
Sending to purchased, rented, or harvested lists
Any activity that poses immediate harm to UNMTA's infrastructure, reputation, or other customers
Illegal activity

6.3 Effect of Termination

Upon termination for AUP violations:

All sending is immediately disabled
No refunds will be issued for the current billing period
You may be prohibited from opening future UNMTA accounts

While we do not routinely monitor the content of emails sent through our Services, we reserve the right to review message content, templates, and sending patterns:

In response to complaints or abuse reports
When investigating potential AUP violations
To ensure compliance with applicable laws
To protect UNMTA's infrastructure and reputation

7.2 Pre-Approval Requirements

We may require pre-approval before you send certain categories of content. If your sending involves content that may require special consideration (high-volume promotional campaigns, regulated industries, or content that has historically generated elevated complaint rates), we may ask you to submit samples for review before sending.

7.3 Infrastructure Protection

We reserve the right to:

Throttle or temporarily suspend sending to protect deliverability
Require changes to your sending practices or configurations
Implement additional verification or security measures on your account
