Frequently Asked Questions
What's the best image size for email marketing?
For most email campaigns, 600px width is the standard. This ensures your images display properly across all email clients without horizontal scrolling. For retina displays, you can use 1200px wide images but ensure they're coded to display at 600px.
How much should I compress email images?
Aim for a balance between quality and file size. Our email presets use 70-90% quality depending on the image type. Hero images can use slightly lower quality (70-80%) while logos and text-heavy images should use higher quality (85-90%).
Should I use PNG or JPEG for email images?
Use JPEG for photographs and images with many colors. Use PNG for logos, icons, and images that require transparency. Note that some older versions of Outlook have issues with PNG transparency.
How can I ensure images load quickly in emails?
Keep total email size under 100KB when possible, use appropriate compression, host images on a fast CDN, and always include alt text. Consider using progressive JPEG encoding for larger images.
Do I need different image sizes for mobile email?
Modern email clients handle responsive images well. Use our standard 600px width and ensure your email template includes responsive CSS. The images will scale appropriately on mobile devices.
