How It Works
Gmail clips emails larger than 102KB, hiding content behind a "View entire message" link. Keep HTML under 80KB and optimize images to avoid clipping and improve deliverability.
How Email File Size Affects Deliverability
Large emails load slowly, use more mobile data, and can be clipped by Gmail. When content is hidden behind a "View entire message" link, fewer subscribers see your full call to action.
Minimise HTML, compress images, and avoid unnecessary styling to keep emails lightweight and fast-loading.
