Hi from the team at Symprex, we hope 2026 is going well for you so far.

This update covers a busy period of work across the platform. Alongside a significant set of internal improvements to reliability, security, and tooling, we've shipped two customer-requested features: the ability to exclude specific users and groups from signature rules, campaigns and disclaimers, and intellisense functionality in our HTML editor.

User and Group Exclusions for Rules, Campaigns and Disclaimers

You can now exclude individual users or groups from signature rules, campaigns and disclaimers. This gives you finer control over how these are applied, without needing to restructure your existing configuration. The exclusion options follow the same familiar interface as the existing user and group selectors.

Template HTML Editor Improvements

As part of our ongoing improvement plans for the template editor, we have introduced IntelliSense autocomplete for our HTML editor, including field completion, operator support, and full Scriban syntax highlighting. These changes make working with functions and template fields easier and help to expose advanced functionality to those customers requiring this.
