There are several reasons why emails may not display correctly:
Email Client Compatibility: Different email clients (like Gmail, Outlook, Apple Mail) render HTML and CSS differently, causing inconsistencies. Responsive Design Issues: Emails that are not optimized for mobile devices may look fine on a desktop but become unreadable on smaller screens. Image Blocking: Some email clients block images by default, which can disrupt the layout and visual appeal of the email. Broken Links: Incorrectly coded hyperlinks or tracking links can break, leading to a poor user experience. Character Encoding: Incorrect character encoding can make special characters and symbols appear as gibberish.
