What's new — week of Aug 17, 2026

This week’s changes brought powerful new ways to personalize your newsletters, connect with HubSpot, and streamline your content workflow.

Audience

• Connect your HubSpot account to sync your contacts into Letterhead, with each HubSpot list appearing as a tag you can use to build segments, and engagement data from your sends flowing back to HubSpot contact fields automatically.

Newsletters

• Show a block to only certain readers by setting conditions based on tags or segments, so different people see different content in the same send without building separate editions.
• Turn on decorative heading lines for an entire newsletter at once from your text styles, rather than switching them on one heading block at a time.

Curations

• Choose a story’s image from your company gallery instead of uploading it again when adding stories to your library by hand.
• Pick curated content from your whole company’s pool when working at the company level, with a filter to narrow by the site a story came from.
