Major Release
Blast Governance – Access Permissions
We've introduced new Blast Access Permissions, giving teams greater control over who can view and manage individual Blasts.
What's New:
Global and Restricted Access: Blasts can now be restricted to specific Team Members and Admins. By default, newly created Blasts are set to Global access.
Private Blast Transition: Existing Private Blasts will automatically transition to Restricted access, with permissions granted to the original Blast Creator and all Admins. Access permissions can be updated even after a Blast has been sent.
Blast Visibility: Restricted Blasts will only appear in Blast tables for Team Members with appropriate access. In Insights, these Blasts will continue to appear as Restricted, or Private in Legacy Insights, for reporting purposes.
Manage Access: A new Manage Access option is available in both the Blast Editor and the ellipsis (⋯) menu in Blast tables, making it easier to review and update permissions.
Access Level Column: A new Access Level column is available in Blast tables to help identify each Blast's visibility settings.
Note: The Access Level column will automatically appear for Team Members using the default Blast table layout. Those who have previously customized their tables can manually add the column using Edit Table.
Minor Improvements
Blasts – Streamlined Navigation
To make accessing your Blasts faster and easier, we've removed the Blasts > Recents page.
Selecting Blasts from the navigation menu will now take you directly to Blasts > Drafts.
News Digest – Header Image Improvements
We've made it easier to customize your News Digest header images with more flexible upload requirements.
Flexible Image Dimensions: Header images now accept any image dimensions and will automatically resize to 600 pixels wide within the News Digest.
Increased File Size Limit: The maximum image file size has increased to 3 MB, with GIF files retaining a separate limit of 1,600 KB.
Audience – Bulk Update Improvements
We've improved the Audience bulk update experience to make managing Manual Segments easier.
Clearer Segment Options: Updated descriptions within the bulk selection tools now clarify that Segment updates apply specifically to Manual Segments.
Segment Search: Added a search option to the Update Manual Segments window, allowing Team Members to quickly find the Segments they need.
Audience – More Flexible Import Headers
Manual Audience imports now recognize both "email" and "email address" as valid column headers for email addresses.
This provides additional flexibility when importing Audience lists without needing to rename columns.
Bug Fixes
Microsoft Teams – Instance Switching
Fixed an issue in the Microsoft Teams integration that could prevent Team Members from switching between Cerkl instances when an instance had no available Content.
