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.

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.

We made progress on the issue impacting the Email Template Builder functionality. Testing for the bug fix has been completed successfully. The leadership team is now coordinating with BeeFree, our email template plugin provider, to determine the best approach for delivering the solution to our customers. Our development team has identified a workaround that has shown the highest success rate so far. When prompted with a blank Email Template Builder screen, they recommend clearing your browser cache and performing a hard reload of the page through the browser console. To assist with this, we’ve included a short video demonstration outlining the exact steps. https://www.loom.com/share/ec7d529983d646b29e8736207ca09512 We appreciate your continued patience as we work toward a permanent resolution and will provide further updates as soon as more information becomes available.

**Root Cause:** Unanticipated updates in either the BeeFree editor or Salesforce infrastructure introduced a timing issue where the BeeFree script began executing before essential page elements were fully available, resulting in frequent failures of the Email Template Builder to load properly. **Resolution:** We modified the EmailEditor page to ensure the BeeFree script initialises only after all necessary page elements have finished rendering. This fix is now included in our April '25 release.
