Dynamic Email is a form tag added by Contact Form 7 – Dynamic Text Extension (DTX) that creates <input type="email"> form fields for forms created with Contact Form 7. It expands upon Contact Form 7’s email field form tag, accepting all of the options it does, along with these additional options introduced by DTX.
| Option | Description | Example |
|---|---|---|
| Dynamic value | Set a dynamic default value. It can be static text or a shortcode. The value is shown in the form tag between quotes. | [dynamic_email inputname "CF7_get_current_user key='user_email'"] |
| Cache Compatible | Enable cache compatibility mode for this field | [dynamic_email inputname dtx_pageload] |
These settings are easily configurable using the form-tag generator.

- If the form tag is required, then it will always have an email address value
- If there is a default dynamic value, it will be checked to validate if it is a valid email address
The dynamic_email form tag was introduced in version 4.0.0 of theย Contact Form 7 โ Dynamic Text Extensionย WordPress plugin.
