Update timeline

  1. identified Jul 10, 2024, 08:11 PM UTC

    For Simon Mail customers, it has been identified that the inclusions of a preheader in both the email template and the campaign configuration causes rendering errors in some email clients, resulting in a blank page. This issue is not immediately discernible because it manifests differently across various email service providers (ESPs). We are actively working on implementing safe guards to restrict this configuration. More immediately, to avoid this issue, clients should refrain from using duplicate preheaders and follow best practices outlined in our documentation. If they encounter rendering issues during testing, they should remove the preheader from either the template or the campaign configuration.

    We are continuing to work on a fix for this issue.

  3. resolved Jul 10, 2024, 10:48 PM UTC

    Safe guards have been implemented to ensure proper rendering in cases of multiple pre header configurations. It is still recommended that best practices are followed per our documentation.
