Find out whether Gmail will clip the email before you send it.

What does the gmail clipping checker do?

Measure the exact UTF-8 weight of an HTML email, see its distance from Gmail’s approximate 102KB clipping threshold, and identify comments, styles, whitespace, and embedded data adding weight. The immediate result is an email-size report with the approximate clipping point. That makes the tool useful when a focused question needs an answer before a file is handed off, a campaign is trafficked, or a production workflow begins.

The scope is intentionally narrow. It is designed for solving one focused email-production problem, not for replacing the complete production process. A useful result should make the next decision clearer while leaving the original file, design, or workflow under the user’s control.

Your files and inputs are processed locally in this browser and are not uploaded to Hypermatic. Local processing reduces unnecessary data exposure, but it does not remove the need to follow the privacy, confidentiality, and retention requirements that apply to the source material.

How should the gmail clipping checker be used?

Start with the same input that will be used in production whenever possible. Draft content, substitute files, and approximate dimensions can be useful during exploration, but the final check should use the actual export, final copy, destination, or supported range.

Work through the steps in order and keep the generated result beside the source. If the result identifies a warning, decide whether it is a real production problem, an acceptable tradeoff, or a limitation of a browser-based inspection before changing the underlying work.

• Paste the final HTML or choose the exported file.
• Measure its encoded size and inspect the markup contributing to the total.
• Trim unnecessary code, then repeat the check using the final ESP-processed message when possible.

How should the result be interpreted?

A browser tool can make measurable signals visible, but it cannot reproduce every application, platform, rendering engine, policy, or team constraint. Treat the report as evidence for a decision rather than a universal guarantee. The strongest verification is the final HTML in the email platforms and client environments the campaign must support.

Pay particular attention to edge cases that are easy to miss during a quick check: unusual fonts, long or localized content, hidden metadata, external dependencies, different aspect ratios, browser-specific behavior, and last-minute source changes. Re-run the tool whenever the production input changes materially.

• Leave a safety margin because an email platform may inject tracking and rewritten links.
• Measure the delivered HTML rather than relying only on the source template.
• Keep the unsubscribe link and other required footer content safely above any clipping risk.

Common questions about gmail clipping checker

At what size does Gmail clip an email? Gmail is widely documented as clipping message HTML at approximately 102KB. The delivered message can be larger than the source because an email platform may rewrite links or add tracking markup.

Are hosted images included in the clipping size? The image files themselves are not included when they are loaded from remote URLs, but their HTML, URLs, attributes, inline styles, and any embedded base64 image data do count.

Is the gmail clipping checker free? Yes. You can use it without an account or signup. The focused result is generated directly in your browser.

When does Emailify become the better workflow?

The free tool is the right choice for a quick individual check, calculation, preview, or template. It remains useful even if the task only occurs once and no broader production workflow is needed.

Emailify becomes more practical when the same job turns into designing responsive campaigns and exporting production-ready email HTML from Figma. At that point, keeping the work close to the Figma source reduces repeated exports, copy-and-paste steps, inconsistent decisions, and handoff drift.

Before adopting any workflow, compare the time spent on the recurring manual process with the setup and review required by the tool. The goal is not to add another application; it is to remove repetitive work while preserving the quality checks that still need human judgment.
