I am not getting submissions from the website, although it says Thank you Submitted

I did a test and a client stated that they submitted forms; however, it's not coming through.

Please assist!!!

It seems to me based on your issue that if a client is telling you they submitted on your embedded form and you didn't receive it you are probably referring to not receiving the email notification.

Have you tried logging into your account to see if the submission is there in the submission viewer?

Please see https://www.jotform.com/help/269-How-to-View-and-Export-Form-Submissions.

If it's not going to your email address then you may first want to check your spam folder and additionally I would recommend these two guides below to assist you further:
