Email autoresponder is not working?

I see that your form in question is form 61186198637467, and its autoresponder functionality appears to be working fine.

Upon checking your form email history, I do see that your emails were being rejected by their recipients, and the reason is simple - you should not use URLs of any kind as the "Sender Name", or subject line of your emails, because your recipients will most likely reject your emails as spam.

In your Sender Name field, please make sure to either use an actual name (such as your personal or company name), or to leave it set to JotForm. All emails that failed had your URL set as the Sender Name and subject of the email:

May I ask also what is the purpose of your forms?

I see that your form 61185963022454 is ranking high in our phishing detector, and seems to be asking for bank account details and PayPal account. This is considered a phishing activity and you must not collect credit card or banking details through our forms, as described in our terms:

Please remove such fields from your form(s), or your account may be automatically suspended. If you are looking to receive payments through your JotForm forms, you must do so through using one of our supported payment tools:
