Why is Testing Across Different Email Clients Important?
Testing across different email clients is crucial because each client renders HTML and CSS differently. What looks perfect in Gmail might be a mess in Outlook. Ensuring that your emails are consistently displayed across various platforms can significantly improve user experience and increase engagement rates.

How Do Email Clients Differ in Rendering?
Email clients differ significantly in how they handle HTML and CSS. For example,
Gmail strips out external CSS and certain HTML elements. On the other hand,
Outlook uses the Word rendering engine, which can lead to unexpected formatting issues. Understanding these differences helps in designing emails that look good universally.
