Clients not receiving emails after submission

Hi,

I had these forms all set and tested and everything was working great.   Then 4.0 happened.   In testing the forms I fill them out and use my own email address so that I can see if it comes in.    I used my personal comcast email address and am still waiting 4 hours now and nothing has come in.    I did a form with my personal gmail address and the client email came in right away.

We are about to take all these forms live and it's going to be crazy making is some people are getting them and some aren't.

Here are the forms I have tested.   I figured if you can help me fix these I can  maybe fix the others.

Thanks in advance

I have checked your forms and received immediately your email auto-responders: 

I have checked your email history and found some blocked emails, you can also check it on your end by following this guide: https://www.jotform.com/help/293-How-to-View-All-Your-Form-Email-History 

What I would suggest you is to first check this guide to avoid email bouncing issues: https://www.jotform.com/help/208-How-to-Prevent-Email-Bouncing-Related-Issues 

You could also check the emails in our bounce list and remove them so they receive emails from JotForm: https://www.jotform.com/help/262-How-to-Remove-Your-Email-Address-from-Bounce-List 

If you're still facing issues with emails not being sent, you could also set up a custom sender email address using the SMTP method, this way you avoid using the Jotform default addresses and use your own mail server info.
