Form submissions beings saved but email not always recieved.

Hello, 

I implemented jotform on our Shopify contact page. The first two forms worked flawlessly and submissions were saved and email notifications were received. However after the first one email notifications were not being sent email. Submission were being saved to the jotform inbox. This behavior happened while doing the Test email function also. 

Hello mac_hoque,

I'm sorry for the trouble caused to you.

Upon checking your forms email alerts, I did not find any issue with it. The submission emails should work normally and you should have received the submission emails.

Our email server log confirms that the submission emails are being sent successfully to email address "mac.hoque@puritycosmetics.com". Please check the logs here:
