Changelog - July, 2025

New Features

Email Config

Subscription-Based Feature Access

The Plugin now enforces feature availability by subscription plan. Some users could previously reach advanced features not included in their plan; that was unintentional and is now fixed. This is less a new feature than a correction, but it affects every other feature, so it belongs here.

All features are now strictly limited to the subscribed plan. On the Plugin for Startup plan, features exclusive to Plugin Expansion or Plugin for Business are no longer accessible without an upgrade to a plan that includes them. Loading a feature outside the plan leaves it uninitialized and prints a warning in the browser console.

This brings behavior in line with the documentation and pricing. For the features in each plan, see https://topol.io/pricing. To keep using advanced functionality, upgrade to a plan that includes the features you need.

Email Docs

New Guide: Topol Plugin Integration with Next.js

A step-by-step tutorial now covers integrating the Plugin into a Next.js application using the official React wrapper. It walks through API token setup, secure configuration, client-only components, and embedding the editor, aimed at developers building in-app email editing with React and Next.js.

The tutorial is in the Tutorials section, or here.

Improvements

Email Blocks

More Support for VML Tags in HTML Blocks

HTML Blocks now allow <v:*> tags, and the HTML editor no longer flags them as invalid.

These <v:*> tags are VML (Vector Markup Language), useful for advanced styling and layout in Outlook, such as rounded buttons or background images that render consistently across versions. <v:rect> and <v:fill>, for example, create a background image with a fallback color in Outlook-specific environments.

Bugfixes

• Email Fixed a major issue where the Video Block often showed colored stripes instead of YouTube thumbnails. If a thumbnail still fails to display, re-enter the video URL in the Video Block Options panel.
• Email The Undo button label in the maximized HTML code editor now correctly reads "Back".
• Email The code editor no longer removes lines on a quick press of the "Fix errors" button.
