HubSpot Marketing Hub Update: An Overview Of The New Email Sidebar

The March 2025 update to HubSpot’s Email Marketing Editor includes a subtle but powerful change: a new sidebar. This is more than a simple cosmetic update – using the sidebar will make designing, editing, and managing your email campaigns even faster and easier. Here’s an overview of what you need to know about the latest feature.

What does the new sidebar include and how does it work?

The aim of the new sidebar is to streamline the email creation and management process by making important features available to users in a more accessible and intuitive format. For example:

Navigation

The new sidebar includes all the most commonly used tools and options in one place, so that instead of searching through various drop-down menus to edit your design settings or content blocks, you can access everything from one place. For regular email users, the time savings will quickly add up, and may also encourage greater uptake of some of the advanced features not used as frequently by users.

Email Building

The drag-and-drop functionality of the email building tools included with HubSpot are one of its most appealing features, and the new sidebar makes it easier than ever to build unique marketing emails in less time. You can now drag elements like images, buttons, and text blocks into your email templates directly from the sidebar, making it easier and more efficient to organise your content.

Dynamic Editing

The sidebar gives you instant access to the personalisation tools you need to tailor each marketing email to its intended audience and to align with your brand identity. Selecting one of your email’s image blocks, for example, reveals suggested image-specific editing options such as resizing. For text blocks, meanwhile, the sidebar might suggest various fonts, styles, and formatting tools. This dynamic feature helps to speed up your editing process and make your email campaigns more consistent in style and appearance.

Quick Links

The new sidebar gives you rapid access to your prebuilt layouts, custom templates, and saved sections, helping your marketing team (and agency, if you’re using one) maintain a brand-specific style and layout across multiple campaigns. The tool also saves time by making it easier for your team to reuse proven components in future emails.

Responsive Design Previews

An email that looks one way on your laptop screen and quite another on your recipient’s phone is a perennial issue with email marketing. The HubSpot Email Marketing Editor now supports real-time previews for a variety of mobile and desktop formats within the new sidebar. This helps you create more responsive designs that look great on every screen size and operating system, while also speeding up the editing process. You won’t need, for instance, to continually switch to your separate preview mode to see how the email looks in different contexts.

Next steps

Taking full advantage of the tools included in the new sidebar will save your team valuable time creating and editing emails, while making it easier for users to adopt the full range of HubSpot email editing tools.
