Webmail rendering covers layout differences across email clients and how to design for consistency.
Webmail Rendering refers to how your email displays in browser-based clients like Gmail and Outlook on the web. Different clients handle HTML and CSS differently, which can cause spacing bugs, broken buttons, or clipped content. Good rendering guidance focuses on simple HTML, tested layouts, accessible buttons, and predictable typography. For automation templates, rendering matters because small issues scale fast across large sends.
