Changelog - May, 2025

New Features

Email Config UX/UI

Custom UI Labels

The new textOverride option replaces any string in the Email Editor, overriding the default localisation wherever needed so the interface uses your own wording.

Overriding a label lets the editor use terminology your audience recognizes while keeping brand consistency. Rename a feature (say Merge Tags to Placeholders), reword the locked-section alerts, or fill a translation gap without waiting for a full release.

Add a textOverride object to TOPOL_OPTIONS. Each key is the dot-notation path to an original string, and each value is the replacement text.

textOverride: {
   "editor.personalisations": "New Label for Merge Tags",
   "forms.section_locked": "New Message for Locked Sections",
// "path to any original string using dot-notation": "Your Custom String"
},

For the full list of editable strings and further details, see the documentation.

Improvements

Email Config UX/UI

More Theme Customization Options

A theme's colors settings now control the background color and opacity of any locked structure or content block, aligning them with your brand or custom color theme. For full details, see the documentation.

Email API

New Endpoint for Deleting Custom Templates

The new Remove Template endpoint deletes templates from your custom library through an API call, so the editor's premade picker only shows the templates you choose. For full details, see the documentation.

Email Config Integration

Conditional Syntax Support for Sparkpost

Setting emailServiceProvider to sparkpost in TOPOL_OPTIONS enables SparkPost's conditional syntax in templates, including conditional chaining with AND/OR operators. For full details, see the documentation.
