Frequently Asked Questions

What is a mailto link?

A mailto link is an HTML anchor tag with a `href` attribute starting with the `mailto:` scheme. When clicked, it instructs the operating system or web browser to open the user's default email program (like Apple Mail, Microsoft Outlook, or Gmail in Chrome) with specified recipient parameters pre-filled.

How do you create line breaks inside a mailto body?

In HTML or standard text, you use `\n` or `<br>`, but inside a URL, you must use percent encoding. A standard carriage return and line feed (CRLF) is written as **`%0D%0A`**. Our generator automatically converts any line breaks you type in the text box into proper `%0D%0A` markers.

Is there a maximum character length for mailto links?

Yes. While the RFC protocol doesn't define a strict limit, many browsers and operating systems impose query limits on protocol handlers. To ensure your mailto link works seamlessly across all versions of Internet Explorer, Chrome, Outlook, and Apple Mail, try to keep the total generated URL under **2,000 characters**.

How do I prevent email scrapers from spamming my mailto address?

Directly publishing `mailto:admin@domain.com` in plain HTML allows bot scrapers to harvest your address for spam lists. You can mitigate this by obfuscating the email link in your source code using hexadecimal entity encoding or loading it via simple JavaScript click event triggers rather than standard anchors.
