    I need the IP addresses to give to my internet provider so they can be whitelisted.

    We have a list of IP addresses, mail servers and domain names available in this user guide. However, the IP list might not be helpful because our IP addresses is constantly changing. You can ask your email provider to whitelist the mail servers and domain list instead. Here's the link: https://www.jotform.com/help/145-Whitelisting-JotMails-IP-Addresses.

    If you're still having email issues, we recommend you to use your own SMTP server as the Sender Email. Here's a guide: How-to-Setup-SMTP-for-a-Form.

    Additionally, you can try adding (noreply@jotform.com) and (noreply@formresponse.com) to your Contact Lists or Address Book.

    Hope that helps. Thank you.
