Ah, it works! Thank you.

This is the formular code:

<table width="600" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td>Dit navn (p?kr?vet)</td>
    <td> </td>
    <td>[text* your-name] </td>
  </tr>
  <tr>
    <td>Din e-mail (p?kr?vet)</td>
    <td> </td>
    <td>[email* your-email] </td>
  </tr>
  <tr>
    <td>Emne</td>
    <td> </td>
    <td>[text your-subject] </td>
  </tr>
  <tr>
    <td valign="top">Din besked</td>
    <td> </td>
    <td>[textarea your-message] </td>
  </tr>
  <tr>
    <td> </td>
    <td> </td>
  <td>Kundet?ller: [checkbox Kundetaeller]</td>
</tr>
<tr>
  <td> </td>
  <td> </td>
  <td>[submit "Send"]</td>
</tr>
</table>

I also included [Kundetaeller] in Message

The source for the “Kundet?ller” cell looks like this:
<td>Kundet?ller: <span class="wpcf7-form-control-wrap Kundetaeller"><span class="wpcf7-checkbox"></span></span></td>
