What is HTML Email?

Quick Answer

An email with formatted design, images, and custom layout built using HTML and CSS.

HTML emails use HyperText Markup Language to create visually rich messages with custom layouts, brand colors, images, buttons, and responsive design. HTML email is the standard for marketing campaigns. Best practices: use inline CSS (not stylesheets), test across 30+ clients, include a plain-text fallback, optimize images (<100KB), and use a max-width of 600px. MisarMail's editor outputs optimized HTML compatible with all major clients.
