Mailto Link Generator is designed for the exact search intent behind “mailto link generator”. Generate a mailto: link with recipient, subject, body and other supported fields using URI-safe encoding. Generate a mailto: link with recipient, subject, body and other supported fields using URI-safe encoding. Basic syntax mailto:user@example.com opens the user's configured mail handler. Query fields Fields such as subject and body are added as query parameters and should be percent-encoded. Client behavior The generated URI requests a compose action; exact handling depends on the user's browser, operating system and email client. Worked example: mailto:hello@example.com?subject=Project%20Update pre-fills a subject in compatible clients. Common practical uses include Create website email CTAs; Prefill support subjects; Build event contact links; Generate copy-ready mailto HTML. Important limitations: Mail-client support varies. Very long URIs can be impractical. A mailto link does not send email automatically. Key questions this page should answer include: What is a mailto link? A URI that opens a configured email client or handler. Can I add a subject? Yes. Can I prefill the email body? Yes where supported. Why encode spaces and special characters? To keep the URI syntactically valid. Does clicking mailto send the email? No. The page should stay focused on this differentiator: Standards-style URI encoding plus clear client limitations. The tool should appear before the explanatory copy so a visitor can complete the task immediately, then use the supporting content to verify the method and understand the result. The explanation should keep terminology consistent with the calculator or converter interface, because a mismatch between labels in the tool and labels in the content can create confusion and weaken search-intent alignment. Where the calculation or transformation has edge cases, the page should state them directly instead of implying that every input is valid. The worked example should mirror the real inputs accepted by the tool and show enough arithmetic or transformation logic for the result to be independently checked.
