Email Builder Errors: Blank Screen

Incident Report for Blackthorn

Update

We're currently investigating an issue affecting the Email Template Builder page and the BeeFree integration used for creating and editing email templates. Some users are experiencing continuous loading when attempting to access the builder.

While we work on a permanent fix, two workarounds have helped some users temporarily regain access. First, performing a hard browser refresh has been effective in some cases. On Windows, this can be done by pressing Ctrl + F5, and on Mac by pressing Cmd + Shift + R. Second, switching to an alternative browser such as Safari or Microsoft Edge has allowed some customers to access the builder successfully.

We will provide further updates as soon as we have more information regarding the root cause and a long-term resolution. Thank you for your continued patience and understanding.

Update

We’re continuing to investigate the issue relating to our Email Template Builder page continuous loading and the BeeFree integration for creating/editing Email Templates.

Our first recommendation is to safelist the following IP Addresses (from the “Network Access” section in the Setup menu) as this has allowed for Email Template creation in several impacted environments. These addresses are used within Beefree SDK for outbound communication:
54.78.90.148
52.16.171.98
52.58.39.32
18.158.188.143

If your team are unable to make those IP Address changes in the “Network Access” Set up menu, there are several email options available in the interim:
Using Classic or Lightning email templates, we’d be happy to assist with configuring a flow to send your communications.
Using your existing marketing tools, we can help generate a Salesforce list of Attendees/Event information to be imported into the tech stack and sent externally.

Please let the Support team know if you need help walking through either path. We’ll be sure to provide an update as soon as we have more information about a resolution.
