Cart layout HTML content is generated when an email trigger runs or when you use the Personalization test send. If you send directly from your messaging provider, you may see older HTML that doesn’t reflect recent cart changes.
Why the email can look the same
Depending on your messaging provider setup:
Profile field method – Cart HTML, for example,
cart_html, is loaded into a profile field in your messaging provider when generated.URL merge method – Cart HTML is requested at send time from a Personalization‑generated URL and merged into the email body.
In both cases, HTML is generated or cached only when:
A trigger in Personalization sends an email.
You use the Test send feature in Personalization.
If you run Test send from your messaging provider only:
The provider uses existing stored or cached HTML.
Recent cart layout edits do not appear in the send.
How to see your changes
To ensure your email uses the latest cart layout:
In Personalization, go to Triggers.
Use the Test send option from Personalization, not from your messaging provider.
Or, trigger a live email send through Personalization.
This forces Personalization to regenerate and send updated cart HTML to your messaging provider.
Tip
If changes still don’t appear, check that your trigger is linked to the correct cart layout in Content > Cart Layout.
