Several factors contribute to lossy issues in email marketing:
Email Filters: Many email clients and servers have filters that may strip out certain elements like images or links to reduce spam. Image Compression: When images are compressed to lower file sizes, some quality is inevitably lost. HTML/CSS Rendering: Different email clients render HTML and CSS differently, which can result in the loss of formatting or even truncation of content. Text Truncation: Some email clients have character limits that can cause the truncation of long emails.
