What Makes an HTML Email Template

What Is an HTML Email Template?

An HTML email template is a pre-designed file that uses HTML (HyperText Markup Language) and inline CSS (Cascading Style Sheets) to create visually appealing and structured emails. These templates can include text, images, buttons, and links, all styled and formatted to enhance readability and engagement.

Unlike plain-text emails, HTML emails can:

• Display images and brand logos
• Use fonts, colors, and layout designs
• Include clickable calls-to-action (CTAs)
• Be mobile-responsive
• Track open rates and link clicks via embedded tracking pixels
