What is the ideal image size for email?

For email body images, 600 pixels wide at 70-80% quality is ideal. This keeps file sizes under 100 KB while maintaining good visual quality across all email clients.

How is this different from Resize for Email?

Resize for Email only changes dimensions. Email Ready Image is a pipeline that both resizes and compresses in one step, producing smaller file sizes optimized for fast email delivery.

What file size should email images be?

Individual email images should ideally be under 200 KB, with total email size under 2 MB. Our default settings typically produce images around 50-100 KB, perfect for email.
