wordperss contact form 7 doesn’t send html content

i’m pretty new to wordpress and contact form, so i’ve installed wp
and contact form 7 and then, i installed ckeditor to make it more nice for the user.

Then, i created a new form with this code:

<p>השם שלך (חובה)<br />
[text* name placeholder "השם שלך"] </p>

<p>האימייל שלך: (חובה)<br />
[email* email placeholder "האימייל שלך"] </p>

<p class="block">נושא<br />
[text subject placeholder "נושא ההודעה"] </p>

<p class="block message">ההודעה שלך<br />
[textarea message class:ckeditor placeholder "תוכן ההודעה"] </p>

<p class="block submit-wrapper text-left">[submit "שלח"]</p>

And those in settings i checked the option “use html content”.
When i sent the email from the site (on the local, using xampp) and the enail was sent but the [textarea message] wasn’t there.
After that, i unchecked the “use html content” and sent the email again.
The message was there but it was a plain text, the html tags were escaped.

Any help? thanks 🙂
