I am not recieving auto responder notification emails.

I have submitted your forms twice with different email addresses and received the email auto-responder in both accounts: 

Maybe the email address you're using is in our bounce list, please provide us with that and we will check it for your. 

You may also check and remove it from our bounce list by following this guide: How-to-Remove-Your-Email-Address-from-Bounce-List

We look forward to your response.
