Unlike plain text emails that only show basic, unformatted words, this means your emails can include your logo, branded colors, buttons, and formatted text.<\/p>\n When someone opens an HTML email, their email client reads the code and displays your design. Most email platforms today support HTML, making it the standard for marketing campaigns<\/a> and customer communications.<\/p>\n Most marketers don\u2019t hand-code these emails because HTML email builders and AI-driven tools automatically generate the HTML behind the scenes, so you can focus on content and design rather than coding.<\/p>\n HTML emails contain two versions in one message: the HTML version with full design and a plain text fallback. Email clients automatically choose which version to display based on the recipient’s settings.<\/p>\n The HTML part controls everything visual: your layout, colors, fonts, images, and buttons. The plain text version strips away formatting but keeps your message and links intact for recipients who prefer simplicity or use older email clients.<\/p>\n Choosing between HTML and plain text depends on your goals and audience. HTML emails excel when you need visual impact and tracking capabilities. Plain text works for transactional messages or audiences who value simplicity.<\/p>\n\n\n
