Pre-configured for Email's limits. Target size: 1 MB · Recommended width: 600px.
Aim for under 1 MB — ideally 200–500 KB. Many clients throttle load time for larger images.
Outlook 2007–2019 shows only the first frame of an animated GIF. Design the first frame to be meaningful on its own.
600 px is the standard email content width for desktop. Use 320 px for mobile-first campaigns.
