Last Updated: April 7, 2026

This Acceptable Use Policy ("AUP") governs your use of the Sendmux platform operated by Jonah and Associates Pty Ltd. This AUP is incorporated into and forms part of our Terms of Service. Capitalised terms not defined here have the meanings given in the Terms of Service.

1. General Principles

Sendmux is an email routing and orchestration platform. You are responsible for all email content routed through the Service, including emails sent by AI agents operating under your account. You must comply with all applicable laws and regulations in every jurisdiction where your emails are sent or received.

Circumvent rate limits, quota restrictions, or access controls
Use the Service to conduct denial-of-service attacks or similar actions against any target
Reverse-engineer, decompile, or attempt to extract the source code of the Service

3. Default Sending Account

The default sending account provided to new tenants is subject to additional restrictions:

Maximum sending volume as published in our documentation
Content must comply with the sending provider's acceptable use policies
We may suspend default account access at any time for abuse, without prior notice
Continued misuse of the default account may result in account termination

4. Email Authentication

You must properly configure email authentication (SPF, DKIM, DMARC) for any custom domains used with the Service. Failure to maintain proper authentication may result in degraded deliverability and is considered a violation of this AUP if it affects the Service's shared infrastructure reputation.

5. Reporting Abuse

If you become aware of any violation of this AUP, please report it to contact@sendmux.ai. We investigate all reports and take appropriate action.

6. Enforcement

6.1 Actions We May Take

If we determine that you have violated this AUP, we may take one or more of the following actions at our sole discretion:

Issue a warning
Throttle or rate-limit your sending
Suspend access to the default sending account
Temporarily suspend your account
Permanently terminate your account
Report illegal activity to relevant authorities

6.2 Process

For non-urgent violations, we will typically notify you and provide an opportunity to remedy the violation before taking enforcement action. For severe violations (such as phishing, malware distribution, or illegal content), we may take immediate action without prior notice.

6.3 Appeals

If you believe enforcement action was taken in error, you may contact us at contact@sendmux.ai to request a review.

7. Changes to This Policy

We may update this AUP from time to time. We will notify you of material changes through the Service or by email. Continued use of the Service after changes take effect constitutes acceptance.
