Standard headers should be 600 pixels wide and 200-300 pixels tall. For retina, create at 1200px and display at 600px. Keep files under 200KB for reliable loading.
Image-heavy emails can trigger spam filters. Maintain at least 60% text to 40% images. Always include alt text and never send image-only emails.
JPG for photographs, PNG for graphics with transparency. Avoid SVG and WebP as support varies across email clients.
One hero header plus 1-3 supporting images is optimal. Too many slow loading, increase spam risk, and distract from your CTA.
Many clients support GIFs but not all. Outlook does not animate GIFs. Design the first frame to work as a static fallback. Keep GIFs under 500KB.
