Hero Images
Does your email pass the ‘squint test’?
The hero image is the wordless proposition of your email.
Does your hero image show your customer what the email is about?
Including text overlay in your hero image?
This is most effective when the text sits at the top of the image and acts as your email headline.
Be sure the font size displays clearly and legibly on small mobile devices.
Get the size right.
Hero images, and all images that span the width of your email should be 600-800 pixels wide.
Resizing your image in your email software yields best results for resolution and accurate sizing.
