If your company's firewalls are generally restrictive (certain commonly used sites are blocked), you will need to allowlist the following email sending domains from Udemy (and all their subdomains) to ensure delivery of invitation emails and operation of the password reset function:
- a) udemy.com
- b) udemymail.com
Please note: the invitation emails are sent in a HTML format. As a result, your email provider must be able to receive emails in a HTML format for users to accept their invitations.
