Rich Text Email

Rich text email allows basic formatting (bold, italics, lists) without full HTML layout.

Definition & Examples

What is Rich Text Email?

Rich text email is an email format that bridges the gap between plain text emails and full HTML emails, offering essential formatting capabilities while maintaining simplicity and universal compatibility. Rich text format (RTF) allows senders to enhance their messages with basic styling elements such as bold and italic text, different fonts and colors, bulleted and numbered lists, and text alignment options, without the complexity of HTML coding or advanced layout design.

This format provides an optimal balance for email marketers who want to improve message readability and visual hierarchy without creating elaborate designs that may render poorly across different email clients. Rich text emails are particularly valuable for maintaining a professional appearance while ensuring broad accessibility and fast loading times across all devices and platforms.
