Terms of Service

Effective November 11, 2026

These terms govern your use of Backburners (backburners.ai), operated by Knudsen Services, LLC ("we", "us"). By creating an account or using the service, you agree to them.

The service

Backburners sends scheduled test emails from mailboxes you connect to seed inboxes we own, and reports where they land. Results are measurements from our seed inboxes and are not a guarantee of how any other recipient's mail provider will treat your email.

Your account and mailboxes

• You must provide accurate information and keep your password secure.
• You may connect only mailboxes you own or are authorized to use, and you authorize us to send test emails from them as described in the service and our Privacy Policy.
• You can disconnect a mailbox at any time from your dashboard.

Acceptable use

You may not use Backburners to send spam or unlawful content, to violate Google's or Microsoft's terms, to interfere with the service, or to access accounts or data that are not yours. We may suspend or close accounts that do.

Fees

If you subscribe to a paid plan, the price and billing terms will be shown before you are charged. Unless stated otherwise, fees are non-refundable except where required by law.

Disclaimers

The service is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not guarantee that the service will be uninterrupted or error-free, or that test results will predict deliverability.

Limitation of liability

To the fullest extent permitted by law, Knudsen Services, LLC will not be liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue or data. Our total liability for any claim relating to the service is limited to the amount you paid us in the 12 months before the claim, or US$100 if greater.

Termination

You may stop using the service and ask us to delete your account at any time. We may suspend or end your access if you breach these terms. Sections that by their nature should survive termination will survive.

Changes

We may update these terms. We will change the effective date above and, for significant changes, notify you before they take effect. Continued use after that means you accept the updated terms.

Governing law

These terms are governed by the laws of the State of Missouri, USA, without regard to conflict-of-law rules. Disputes will be resolved in the state or federal courts located in St. Louis County, Missouri.
