• Use Alt Text: Ensure accessibility when images fail to load.
• Test Across Email Clients: Make sure your images look good on all platforms.

FAQs

What is the best image format for email newsletters?

JPEG is generally best for photographs, while PNG is ideal for images with text or logos.

If a photo is already a PNG and does not need transparency, follow the PNG-to-JPG conversion steps to create a smaller, broadly compatible copy.

Can I use GIFs in emails?

Absolutely. GIFs are great for animations but make sure the file size is manageable.
