How to Embed Images in Email: CID, HTML Inline & Linked Images

The text provides an overview of methods for embedding images in emails, focusing on three main techniques: CID (Content-ID), HTML inline embedding with Base64 encoding, and linked images. Each method is examined for its advantages and disadvantages, such as compatibility with various email clients, impact on email size, and ease of implementation. CID images, while supported by many desktop clients, often do not display correctly in webmail services like Gmail. Inline embedding simplifies the process but can increase email size significantly, while linked images keep emails light but may face blocking issues. The text also emphasizes the importance of testing emails across different clients and devices to ensure images render correctly and highlights best practices like using alternative text for accessibility. Additionally, it warns against relying solely on images in emails to avoid deliverability issues and suggests maintaining a balanced image-to-text ratio. The text concludes by advising readers to consider their audience when choosing an embedding method and to test emails thoroughly before sending.
