Email Size Checker
Check your email HTML size, image count, and Gmail clipping risk. Gmail clips emails over 102 KB, hiding your footer, CTA, and unsubscribe link.
About this tool
Gmail clips emails larger than 102 KB, cutting off the bottom of your message and replacing it with a "[Message clipped]" link. This means your call-to-action, footer, and even your unsubscribe link can disappear. Use this tool to check your email's HTML size before sending. Keep emails under 50 KB for best results. If your email is too large, reduce inline CSS, minimize table nesting, and compress images. For a comprehensive deliverability check, run your domain through our deliverability score checker and verify your SPF records, DKIM setup, and DMARC policy.
