Whitelisting JotForm IP Addresses and Domains

Whitelisting JotForm IP Addresses and Domains

Please contact your email service provider and request them to add JotForm's IP addresses to their whitelist.

It is also a good idea to add and to your contacts lists and whitelist our common domain names below.

    We are not getting the verification code when adding a replacement email into sender email so it will be from our google apps g-suite account - This is confusing for us. Can you guide us please.

    This is a non profit account and the board members change every 2 years so we prefer not to do the smtp with a user name and password as that will change every 2 years.


    Customize the content of the email and the address of the sender.

    Users can receive emails using your own SMTP server instead of JotForm's servers.

    I have had my network admin whitelist everything in this list however Outlook is still placing jotform submission emails into quarantine...

    Can you please assist?

  • sophiamanley

    I am having emails being rejected from sending on gmail coming from IP addresses other than these.

    Are there any additional IP addresses that are not listed?

    I am going through them all and so far am seeing two that are being rejected and that are not listed on this list.

  • agmark

    The largest subnet Exchange Online will allow whitelisted in the connection filter is /24. This is a huge list. What are other options? Can our emails be narrowed down to a specific range?

  • BrightstarTelecom


    I've added 3 of the JotFrom emails to my Gmail contact.

    But I can't find where I can add the whitelist of domains list and IP.

    Can you please provide guidance to me?

    Thanks - Billy

    We use Rackspace web mail and when trying to add IP addresses above, the window says that the IP address is not valid.

    Please assist further. I am not a technician and I do not understand what I am doing incorrectly.

  • jniewenhuis

    Which one of these can I use for FTP? At least a FQDN. Please help...
    Thank you.

  • Russell Durtschi

    How about getting yourselves off of blacklists so we don't have to whitelist a bunch of stuff.

  • Dion Hardin

    I am attempting to access this link and it times out every time. I can whitelist my client and it works. I have added the whitelist information above and that does not work either. Any extra advise or is there possibly a redirect somewhere that is causing this timeout?

    Thank you

  • ModernDayAgent

    Well, I got yours but why did I not get my clients reports?

  • kumc

    Would it be possible to notify your customers when this list is updated?
    It would allow us to better serve our customers. Please and thank you.

  • Judy Boles

    I am not getting JotForm notifications on my Comcast email. How can this be fixed?

  • netcent

    Huh? No one in their right mind would whitelist this list!

    Whitelist all of amazonaws as a sender? Really?

    Class Bs and Cs you don't even own or control?

    Do you have any idea how many attacks and how much spam comes from some of these ranges?

    I don't know who came up with this but you've just made the decision of renewing very easy.

    What is the latest list? Is there a dedicated support article for office 365?

  • Eric Williams

    This list is no longer current. Please update with a current list of IP addresses that we need to add to the white list:

  • marcusantebi


    This happened with one of my email accounts and there was something you were able to do on your end to get them not to bounce.

    Can you please do that again for the email address:

    Thank you!

    I have not been receiving forms that are filled out, and just now forwarded them through jot form, but they have not arrived either. what the heck is going on, I've received close to 100 forms already, this is really annoying that it would stop now.

  • Book of Charms

    I found it :)
    My apologies for the inconvenient :)

  • Book of Charms

    Hello, I have a question :)

    Thank u very much.
    Good Day :)
