I want to be able to mailto all user with a link/button.

To display one user mail is @syv.ePost:

@{
    var syvs = CurrentPage.Children.OrderBy("kommun");
}

  @foreach (var syv in syvs)
                        {
<tr>
 <td data-title="E-post">
                                    @if (!string.IsNullOrEmpty(syv.ePost))
                                    {

                                        <a href="mailto:@syv.ePost" target="_top">@syv.ePost</a>
                                    }
                                    else
                                    {
                                        <text>&nbsp;</text>
                                    }
                                </td>
                            </tr>

This will list all e-mails.

Now I want to make a button that mails to all when clicking it.

I tried doing like this:

   @*@foreach (var syv in syvs)
        {
           <a href="mailto:@syv.ePost" target="_top">@syv.ePost</a>

        }*@

But this list all the mail again. I want one link that mails to all. How do I do it?
