Checks - Email Love

The Builder checks every email as you edit it. Checks catch things like empty required fields, links that go nowhere and missing alt text before the email leaves the Builder.

Where checks show

Insights: the lightning icon at the top of the right panel opens Email insights. It lists what to fix, with Open field to jump to each one. Click Refresh checks to run them again.
Share: the first line of the menu says All checks pass, how many warnings to review, or how many issues block export.
The Style panel: with nothing selected, a link shows how many things to look at in Insights. A selected section shows its own checks.

Always checked

These run on every email:

Required fields are filled in.
Every image has alt text or is marked decorative.
The email has a subject line.
Links use https, mailto, tel or a merge tag.
No placeholder images or empty buttons are left.

Team checks

Team checks are rules your team chooses for a design system. Set them in the design system’s Brand styles › Team checks. Each one is Off, Warn or Block.

Check	What it looks for
Links go somewhere real	No placeholder addresses like example.com or #, and no empty button or navigation links.
Merge tags are set up	Every merge tag exists in the workspace, so none shows as plain text.
Preview text is set	The email has preview text. Without it, inboxes show the first words of the email.
Subject length	The subject isn’t so long that inboxes cut it off.
Required phrase in subject or preview text	The subject or preview text includes a phrase you set.
Under Gmail’s 102 KB limit	The email is small enough that Gmail won’t hide the end of it.
No starter text	No lorem ipsum, “Add your CTA” or Assistant placeholders left in the email.
Unsubscribe link	The email has a link to unsubscribe or manage preferences.
Components are up to date	Every section uses the latest published version of its component.
Links have UTM tracking	Tracking is added to web links on export.
Words to avoid	Words from the Words list in AI knowledge, with what to say instead.
Footer dates match this email	Dates in the footer’s small print that the rest of the email doesn’t mention.
Text has enough contrast	Text that’s hard to read against its background.
The headline is an H1	In Assistant drafts, the main headline is a real heading and nothing is bigger.
Links go where their words say	A button or link whose words don’t fit where it goes.
Best sellers are filled in	Empty best-seller slots when the brand guide lists products.
No repeated buttons	Two buttons in a row that go to the same place.

The last five only warn. They can’t block.

What Block does

A check set to Block stops the email leaving the Builder until it’s fixed. That covers Copy HTML, Download HTML, Download MJML, Download PDF, pushes to your email platform, Publish to web and Export to image. Test emails still go, so you can check a draft in an inbox. Warn shows the problem but doesn’t stop anything.
