The Autoresponder email is not being sent

To whom it may concern, 

I create a registration form, and the registration is working but the autorresponse email is not being send. I followed all your instructions, but I still it is not working.

Could it be because I used the encrypted form? I try to find how to change this settings in case that was the problem, but I did not find them. 

Could you please help me?

Thank you for you promt answer. 

Thank you,

I set your autoresponder sender email to our default sender. It's blank earlier when I checked it, maybe that's the reason why autoresponder is not sending.

Can you please check and try submitting your form if you can receive the autoresponder?

Let us know how it goes :)
