Mailto Link Generator: A Practical Guide
Use Mailto Link Generator to prepare an email URI with an address, optional subject and message. Opening a mailto link asks the visitor’s configured email application to compose a message. It does not send email automatically.
How to Use Mailto Link Generator
- Enter Email address.
- Add the desired Subject and Message.
- Generate the mailto URI.
- Use it as a link destination and test with an email application.
A Compose Action, Not a Send Action
The generated URI encodes subject and body parameters. Support and formatting can vary between email clients. Long prefilled messages may exceed practical URL or client limits.
The recipient address becomes public when the link is published. Do not place confidential information in the prefilled message or assume that clicking the link confirms a successful email.
Worked Example
A Contact sales link can prefill a subject such as Product enquiry. The visitor still reviews the draft and chooses whether to send it.
On a device without a configured mail handler, the link may open a setup prompt or fail to start a composer.
Wrap an ordinary web URL in an anchor: use the HTML Link Generator.
Understand encoded parameter values: use the URL Encoder.
Checks and Common Mistakes
- Check the address for typos.
- Keep prefilled content concise.
- Do not put secrets in a public URI.
- Test line breaks and special characters.
Frequently Asked Questions

No. The visitor’s email client controls composition and sending.
Why does nothing open?
The device may not have a registered email handler.
Can I use it as a contact form?
It is a different workflow and depends on the visitor’s mail application.
