- Device & OS
- not provided
- Scenario
- Submitting a PDF form by email using a mailto action and attempting to include formatted links in the generated message.
- Observed behavior
- HTML links in the email body appear as plain text tags rather than formatted, clickable hyperlinks.
Before configuring your PDF form's email submission button, note that the 'mailto' protocol does not support HTML formatting. Have your complete, raw URLs ready to use instead of HTML anchor tags.
Use Full Plain Text URLs in the Email Body
Since PDF mailto actions send data as plain text, providing the complete URL ensures most modern email clients will automatically convert it into a clickable link.
A PDF mailto action does not interpret HTML anchor tags (like <a href="...">). Instead, it sends the entire email body as plain text.
Because of this universal protocol limitation, you cannot reliably force a formatted hyperlink from the PDF side. The recipient's email application is ultimately responsible for detecting URLs and making them clickable.
Open your PDF form editor, right-click the button configured for email submission, and select 'Properties'.
In the Properties dialog box, click on the 'Actions' tab to view the button's behavior triggers.
Select your 'Submit a form' or 'Execute a menu item' action that contains the mailto string and choose to edit it.
In the body parameter of your mailto link, type the complete URL including the protocol (e.g., https://www.example.com) instead of using HTML tags. Save the changes.

Frequently Asked Questions
Why do my HTML tags show up as text in the email generated from a PDF?
The 'mailto' protocol used by PDF forms only supports plain text. Any HTML tags, such as anchor tags for links, will be passed exactly as written rather than being rendered as formatted web elements.
Can I force the recipient's email client to make the link clickable?
No, you cannot force this from the PDF side. However, providing the complete URL (starting with http:// or https://) makes it highly likely that the recipient's modern email client will automatically convert it into a clickable hyperlink.
Is there a workaround to send HTML emails from a PDF form?
A direct mailto action cannot send HTML. A common workaround is to submit the PDF form data to a custom server-side script (like PHP) via a web URL instead of an email address. The server script can then format the collected data into a rich HTML email and send it securely.
Does this plain text limitation apply to all PDF readers?
Yes, this is a universal limitation of the standard mailto URL scheme and how desktop email clients process data passed from external applications. It is not a restriction specific to Acrobat or WPS PDF.
