Email Quality Checks

What it is

Email quality checks are a built-in AI review in HubSpot's email editor that scan an email before send. They look for spelling and grammar issues, spam triggers, broken links, missing token fallbacks, date formatting, a weak first-sentence hook, off-brand voice, and more. Teams can also add custom AI-powered checks for specific voice, tone, or content requirements, and adjust severity to match how strict the review should be. This is now in public beta for Marketing Hub Starter, Professional, and Enterprise.

Why it matters

Pieces of this have already existed. HubSpot has been flagging missing token fallbacks and broken links for a while. The new and meaningful piece is the breadth, especially the custom AI voice and tone checks. Most teams have a quality bar that lives across test sends, browser extensions, and Slack pings to a teammate, and those reviews never quite scale. Now that it's rolling out more broadly in public beta, bringing that review into the editor where the work happens compresses the loop for a lot more portals at once.
