CF7 won't send…

Hello,

I am trying to setup a contact form but it is not sending…

My contact form is a little bit complicated because I added HTML and CSS, I don’t know if this is the problem.

<p><table style="width:100%" div="tablecontact">
  <tr style="height: 50px;">
    <td class="desccontact"><p>Nom <b>(*)</b></p></td>
    <td><p>[text* votre-nom id:champnom]</p></td>
  </tr>
  <tr style="height: 50px;">
    <td class="desccontact"><p>Prénom <b>(*)</b></p></td>
    <td><p>[text* votre-prenom]</p></td>
  </tr>
  <tr style="height: 50px;">
    <td class="desccontact"><p>Adresse e-mail <b>(*)</b></p></td>
    <td><p>[text* votre-email]</p></td>
  </tr>
  <tr style="height: 50px;">
    <td class="desccontact"><p>Téléphone <b>(*)</b></p></td>
    <td><p>[text* votre-telephone]</p></td>
  </tr>
  <tr style="height: 50px;">
    <td class="desccontact"><p>Ville <b>(*)</b></p></td>
    <td><p>[text* votre-ville]</p></td>
  </tr>
  <tr style="height: 50px;">
    <td class="desccontact"><p>Année de naissance</p></td>
    <td><p>[text votre-annee placeholder "JJ-MM-AAAA"]</p></td>
  </tr>
  <tr style="height: 50px;">
    <td class="desccontact"><p>Comment souhaitez-vous être contacté(e) <b>(*)</b></p></td>
    <td><p>[checkbox votre-choix "E-mail" "Téléphone"]</p></td>
  </tr>
  <tr style="height: 50px;">
    <td><p></p></td>
    <td><p>[submit "Envoyer" class:boutonenvoyer]<input type="reset" class="boutonreset" value="EFFACER"/></td>
  </tr>
</table></p>
