Open a marketing email from almost any company today, and you will see heavy layouts, bright images, custom web fonts, and interactive buttons. But look at communications between software engineers, system admins, and open-source contributors, and you will find they almost exclusively use plain-text emails. Why?
1. Speed and Bandwidth
An HTML email can easily be several hundred kilobytes in size. A plain-text email is usually just a few kilobytes. For developers working in terminals, over slow SSH connections, or simply valuing speed, plain-text loads instantly, every single time.
2. Uncompromising Security
HTML emails can execute scripts, load remote tracking pixels, and trigger vulnerabilities in email clients. Plain-text contains zero executable code. It cannot load remote assets, meaning it is impossible for senders to track your reading habits or infect your machine with malware.
3. Accessibility and Device Compatibility
HTML layouts often break on different screens, especially on smartwatches, e-readers, or terminal-based email clients (like Mutt). Plain-text is universally supported, readable by every screen reader, and looks perfectly clean on any device.
This is why Echo Line displays emails in text-only format. It keeps you safe, saves database storage, and delivers the raw information you need without marketing bloat.
