Gmail message is clipped when email is triggered through a published AJO Journey, but the same email is not clipped during Proof Testing

Question

We are facing an issue with an email created using the AJO Drag-and-Drop Email Designer.

Proof Testing: Email is received in Gmail and renders completely without clipping.
Published Journey: The same email is received in Gmail with “Message clipped – View entire message.”
AJO Content Check shows “No issues detected.”
We are using the Drag-and-Drop implementation and do not see an Optimize HTML size option.

Could you please help us understand why the email is being clipped only when triggered through the published Journey and how we can prevent Gmail from clipping the message?

Please also confirm whether Journey execution/personalization/tracking can increase the final HTML size compared with the Proof Test version.

We can provide the Journey, email template, recipient details, and screenshots if required.

​@shivangisinghGmail clips anything over ~102 KB of raw HTML — not image size, just markup/text/links. Proof Tests and published journeys don't produce identical HTML, so the published one is likely crossing that line.Yes, tracking + personalization can increase final HTML size vs. Proof.Multiple reasonssuch asTracking (Click/open tracking is on by default, and it rewrites every link into a long Adobe redirect URL. More links = more bytes),Mirror page link is inactive in proofs and only goes live in the real send, adding size only in production, and also, Proofs use test/sample profiles so real profiles can trigger longer loops, offers, or fallback text than your test data did.
