Image blocking
Image blocking is when an email client prevents images from loading automatically in a message.
Image blocking occurs when an email service disables the automatic display of images within emails to protect user privacy or reduce bandwidth. This can affect how recipients perceive an HTML email, as visual content may be hidden until they manually allow images. Marketers must account for image blocking by using alt text and ensuring the email's message is still clear without images, as it impacts engagement and tracking.
