Hey everyone, I'm hoping to tap into the collective wisdom of this subforum on a pesky Gmail clipping issue that's been driving our team a bit batty this week! 😅

We're sending a fairly standard HTML newsletter via our ESP (Postmark, in this case), and a significant portion of our Gmail recipients are seeing the dreaded "Message clipped" view. The classic advice is to check for overly long lines in the HTML source, which we've done meticulously. We're using a proper HTML template with a head and body, our CSS is mostly inline (with a style block for media queries), and we've run the raw source through every linter and validator we know. No single line exceeds even 500 characters, let alone the 998-character limit often cited. We're also well under the 102KB total size threshold.

Here's a simplified skeleton of our template structure, which I *thought* was clean:

```html

/* Media queries here */

```

Things we've already ruled out:
* **Line length:** As said, we've minified and beautified the code. Lines are short.
* **Total size:** The entire HTML document is ~85KB.
* **ESP additions:** We've inspected the raw source Postmark sends out. No huge tracking pixels or appended content is pushing us over a limit.
* **Content:** It happens even with very text-light, simple promotional emails.

My current hunch is that it might be related to **how Gmail's proxy processes the HTML**, perhaps counting something differently, or maybe something about our nested table structure (though it's only 2-3 levels deep). I'm also wondering if the `style` block in the head, despite being valid, could be a factor.

I'd love to hear from anyone who's fought and won this battle:
* Did you find a "hidden" culprit, like a specific character count *after* Gmail's processing?
* Are there particular HTML elements or attributes that seem to trigger clipping?
* Any tools besides the usual validators that gave you a true "Gmail's-eye view" of the message?

I'm a big believer in automating diagnostics, so if there's a way to script a test for this, I'm all ears! Thanks in advance for sharing your war stories and solutions.

Happy integrating,
Bob
