Terms of Service
Last updated 2 July 2026
These terms govern your use of SPFWise. By using the site or its tools, you agree to them. If you do not agree, please do not use the service.
The service
SPFWise provides tools to analyze the public email-authentication configuration of a domain and to explain and help fix issues. The free tools are available without an account. Paid plans, when offered, add monitoring, reports and related features under the plan you choose.
Acceptable use
Use SPFWise only for lawful purposes. Do not use it to attack, overload, or probe systems you do not own or have permission to test, to scrape or resell the service at scale, or to attempt to break, reverse engineer, or disrupt it. We may rate-limit or block abuse.
Accuracy
We work hard to read DNS correctly and grade it fairly, but DNS can be inconsistent, cached, or mid-change. Results are informational and are not a guarantee about your deliverability or security. Always confirm important changes yourself before relying on them.
Availability
The service is provided on an as-available basis. We may change, suspend, or discontinue any part of it at any time, and we do not promise it will be uninterrupted or error-free.
No warranty
SPFWise is provided as-is and as-available, without warranties of any kind, whether express or implied, including fitness for a particular purpose. You use it at your own risk.
Limitation of liability
To the maximum extent allowed by law, SPFWise is not liable for any indirect, incidental, or consequential damages, or for any loss of mail, data, revenue, or reputation, arising from your use of or inability to use the service.
Changes to these terms
We may update these terms from time to time. Changes take effect when posted on this page, and the date above will reflect the latest version.
