At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
We are sending the form emails based on our logs. You can check your email history for more information: https://www.jotform.com/help/364-Why-I-am-not-receiving-email-notifications. Please check your spam folder for the emails and make sure to mark them as not spam.
I see that you are using a custom email address as the sender email of the form, you have it through SMTP method. You may consider asking your hosting provider if they can find some logs related to your email account. They have the control to check this for you.
Lastly, try to separate the recipients in the form into different notifiers. One notifier for each recipient. Check if that works.
