Mailto Generator prepares a mailto link containing an email recipient and supported message fields such as subject and body. A mailto link asks the visitor's configured mail application to compose a message. It does not send the message automatically, and behavior depends on the user's installed client, browser settings, and support for optional fields. Web development utilities are useful for checking a focused part of a page before integrating it into a larger design. The browser, document structure, styles, and surrounding application still affect the final behavior. Start with a clear example and a specific destination, such as a stylesheet, page head, link, or test fixture. After preparing the result, check it in context and at more than one viewport size where relevant. A small isolated preview cannot demonstrate every interaction with an existing website.

How to use this tool

1. Enter a short example that represents the intended page or design. Keep the original values available so you can compare the result.
2. Enter the recipient and desired message fields, generate the link, and test it with the mail client used in your workflow.
3. Review the example below and compare its expected behavior with a small sample of your own input before continuing.
4. Use the result in a small test page or relevant browser workflow, then check its appearance and behavior before adding it to a live website.

SEE IT IN PRACTICE

A worked example

Recipient hello@example.com; subject Hello world

mailto:hello@example.com?subject=Hello%20world

Spaces in query values are percent-encoded so the subject can be represented safely in a URL-style link.

A mailto link delegates to the user's client

Clicking the link normally opens a compose window in the configured mail application, where the user can review and send the message. The site does not receive a delivery confirmation from generating or opening that link. A visitor without a configured client may have a different experience, so keep a readable contact address available when practical. Optional fields such as subject and body are conveniences, not a guarantee that every mail client will preserve the same formatting.

Encode fields without hiding their contents

Spaces, line breaks, ampersands, and other punctuation need suitable URL encoding in query values. Test a subject containing a space and a short multi-line body before relying on a longer template. The address and prefilled message are visible in page source and can be copied, so avoid embedding private information. Keep prefilled text concise and useful rather than assuming a mailto link can serve as a complete form submission system with validation and tracked delivery.

When this tool is useful

• Create a contact link with a useful subject
• Prepare a prefilled support inquiry link
• Understand mailto URL encoding

Tips for a better result

• Check recipient spelling, subject encoding, line breaks, and the behavior when no default mail client is configured.
• Inspect the result in its actual context. Inherited styles, relative paths, document structure, and browser support can change how a correct-looking snippet behaves after integration.
• Keep the source and the settings used for this result together. That makes a later comparison or correction easier, especially when another person needs to reproduce the same outcome.
