    Comcast Emails Not Receiving JotForm Notifications

    Asked by BrenKoch on January 22, 2015 at 09:07 AM

    For some reason the notifications emails will not work with Comcast.net emails. When I signed up I did not even get the intro email. I saw it when I looked at the email log. It seems to be going out but is not being received, although I tried with several Comcast emails. It works with gmail.  Is there an issue specifically with Comcast.net emails?

    Thank you,

    Hi Brenda,

    I believe Comcast might be blocking our JotMail IP addresses, please try contacting them and ask to whitelist our IP addresses and domains? Here's a guide on what you might need to do or tell them.

    To prevent bounce related issues you can check this guide:


    For general whitelisting of our JotMail IP addresses see this guide:



    I would recommend that you check both guide to troubleshoot your email notifications correctly.

    I hope this works. Let us know if you need more assistance.

    Thank you.
