By accessing or using WhyIsMyEmailLate (the "Service"), you agree to be bound by these Terms of Service. If you do not agree with any part of these terms, you must not use the Service. These Terms apply to all visitors, users, and anyone else who accesses or uses the Service. We reserve the right to update these Terms at any time, and your continued use of the Service after any modification constitutes acceptance of the updated Terms.
WhyIsMyEmailLate is a free, browser-based utility that parses raw email headers to visualize SMTP routing paths and calculate transit delays between mail transfer agents. The Service is provided for informational and diagnostic purposes only. All analysis runs client-side in your browser; no email data is transmitted to or processed by any server operated by WhyIsMyEmailLate. The Service does not send, forward, block, or otherwise interact with any email messages.
The Service is provided "as is" and "as available," without warranty of any kind, express or implied. WhyIsMyEmailLate makes no representations or warranties regarding the accuracy, completeness, reliability, or fitness for a particular purpose of any analysis output. Email header timestamps are self-reported by individual mail servers and may be affected by clock synchronization errors, server misconfiguration, intentional header modification, or other factors outside our control. Analysis results are diagnostic estimates intended to guide investigation — they do not constitute verified measurements, legal evidence, forensic proof, or any form of certification regarding email delivery. Do not rely solely on this tool's output to make business-critical decisions without independent verification.
To the fullest extent permitted by applicable law, WhyIsMyEmailLate and its operators, employees, contractors, and affiliates shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages — including but not limited to loss of profits, loss of data, or business interruption — arising out of or related to your use of or inability to use the Service, whether based on warranty, contract, tort (including negligence), or any other legal theory, even if WhyIsMyEmailLate has been advised of the possibility of such damages. Your sole remedy for dissatisfaction with the Service is to stop using it.
You agree to use the Service only for lawful purposes and in a manner that does not infringe the rights of others. You must not use this Service to analyze email headers obtained without proper authorization or consent from the email account owner. You must not use the Service in any way that violates applicable local, national, or international law or regulation. You must not attempt to reverse engineer, decompile, scrape, or systematically extract data from the Service. You must not use automated tools to generate artificial traffic to the Service. We reserve the right to terminate access to the Service for any user we believe is in violation of these terms.
