This article covers the SPF authentication process for JotForm and how it's managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

At present time, JotForm does not support DKIM signing for custom domains.

Please consult this article to find out what are JotForm's sending IPs and their sender domains list.

For any issues regarding SPF alignment for your custom domain, please contact JotForm's support team, here.

Once you establish that JotForm is an authorized sender for your domain, you will need to add the service in your Enabled Senders.

You will find more detailed information on how to add a service for your domain in Valimail, here:

Note: We encourage you to use the comment section for any useful information about your sending service, such as the name of the service owner, change request ticket numbers, etc.
