# Use Reply-To header when available

You can enable or disable this setting in `Queue > Edit`.

This feature is handy in situations where you have an external form where you ask your visitor to share their email address among other things. The form is set up to send the contents as an email to some email address, and puts the visitor email address in the Reply-To header.

This is how a Wordpress "Contact Us" form works for example.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.supportress.com/queues/use-reply-to-header-when-available.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
