Email Quality Checks
Friday, September 25, 2026
What it is
<p>Email Quality Checks are a built-in AI review in HubSpot's email editor. They scan your email before you send, looking for spelling and grammar, spam triggers, broken links, missing token fallbacks, date formatting, a weak first-sentence hook, off-brand voice, and more.</p>
Why it matters
<p>That review used to live across test sends, browser extensions and Slack pings to a teammate. Email quality checks bring it into the editor you are already working in.</p>
The Take
Ooh, broken links stands out to me.
Broken links is the check that stood out to Madelyn first, ahead of spelling and spam triggers, because it is the one that gets past a human read every time. She has started seeing the checks in the portals she works in, and as a self-described terrible speller she puts spelling help near the top of what AI is actually good for. The hidden gem is custom checks. Product marketers can encode the rules they keep repeating to the sales team, always call it this and never describe it like that, so whoever is sending the email that week gets the same guardrails without a Slack ping. Casey's example from a client was orphan lines, the single word left stranded on the last line of a paragraph; it is not clear the checks get that granular yet, but it is the kind of formatting rule this is built to hold.
