Time lag with filling out form and receiving confirmation

I am experiencing 15-20 minutes before someone fills out my form and I receive the email. Any ideas?

I've sent a test submission to the form and immediately I checked for email history to see if the email delivered. I was able to see that the email delivered as soon as we receive the submission.

The latency could be due to the email server. I request you to go through the guide on setting-up-email-alerts-to-prevent-email-bouncing-related-issues and follow the instructions provided. Also, Whitelisting-JotMails-IP-Addresses should help in avoiding some issues with receiving emails.

Please get back to us if the issue still persists. We will be happy to look into this issue further.

Thank you!!
