Email Quality Checks

What is it?

Email Quality Checks are a built-in AI review in HubSpot's email editor. They scan your email before you send, looking for common issues: spelling and grammar, spam triggers, broken links, missing token fallbacks, date formatting, a weak first-sentence hook, off-brand voice, and more.

 

Why does it matter?

Sending email well means catching the small things and the strategic ones: a stray typo, a token that never populated, a subject line that reads as spam, a first sentence that won't pull anyone in, a brand voice that drifts off. Today that review lives across test sends, browser extensions, and Slack pings to a teammate. Email quality checks bring it into the editor you're already working in.

 

How does it work?

Open an email in HubSpot, click "Quality check," and the panel runs every enabled check against your current email content. Results come back grouped into errors, warnings, and suggestions.

 

Click any issue to jump to that spot in the editor. Many issues identified include a one-click auto-fix.

In Settings > Marketing > Email > Quality Checks, you can toggle checks on or off.

Includes out-of-box quality checks that scan your email for issues related to:

  • - Spam (Does anything about this email increase the risk of being treated as spam?)
  • - Grammar (Are there typos or grammatical errors like incorrect punctuation, sentence fragments, etc?)
  • - Semantic meaning (Does this email make sense as a whole, is it consistent with no contradictory claims?)
  • - Brand voice (Does this email align with our organization’s configured brand voice?)
  • - Personalization check (What is the fill rate for personalization token used in email based on my audience I'm sending to?)
