keytoe on "[Plugin: Contact Form 7] Get email form form on_sent_ok"

Hi,

I have succesfully updated the success message after submitting contact form 7 on my wordpress site.

However, I would like to be able to display the e-mail address in the succes message. Is this possible and if so, how can I do that?

I need the e-mail adres for a tracking pixel which I'm implementing. The img is correctly shown right now, but I'm missing the e-mail address:

on_sent_ok: "var div = document.getElementsByClassName('wpcf7-response-output wpcf7-display-none wpcf7-mail-sent-ok')[0].innerHTML = '<img src="https://tl.tradetracker.net/?cid=10978&pid=16524&tid=datumplaatsen&eml=<?php echo $_POST['your-email']; ?>&descrMerchant=viaofferteform&descrAffiliate=viaofferteform" alt="" width="1" height="1" border"0" />'"
