Change Email Recipient Based on Field Value

Yes! You can use field values in the Email To field.

For example, the To field can be [DEPARTMENT]@mc4wp.com

And then in the form you would have

<select name="DEPARTMENT" required id="department">
    <option value="" disabled selected hidden>Select</option>
    <option value="support">Support</option>
    <option value="admin">Administration</option>
  </select>

I do strongly recommend to not set the whole email address dynamically, as that would allow someone to send emails to arbitrary addresses via your site. That is why in the above example the domain is “hard coded” and only the part before the @ sign is dynamically set by the website visitor.

Hope that helps. If you have any questions, please let me know!
