Image Blocking
When email clients stop images from loading automatically, so people see empty boxes or alt text instead of pictures. This protects users from tracking and unsafe content, so you should never rely only on images to tell your message.
Image blocking is when an email app holds back your images until the person clicks to show them. The text loads, but the pictures do not. People might see empty boxes or your alt text instead of your design. It is common in tools like Gmail, Outlook, and Apple Mail.
This matters because a big image only email can look broken when images are off. If your logo, product photos, or main call to action live only in images, many people will miss them. That can hurt clicks and sales. It also makes your brand feel less trustworthy.
A simple way to handle image blocking is to write strong alt text and plan for a text first layout. Put key details like offers, prices, and buttons in real HTML text. Use images to support the message, not carry all of it. Before you send, preview your email with images turned off and check that it still makes sense.
