Email Preview
Preview HTML, Markdown or .eml email at phone, email and desktop widths; flag what Gmail and Outlook don't support; plain-text version.
About this tool
Paste an email's HTML or Markdown, or open an .eml file, to see it at phone, email and desktop widths, with a list of what Gmail and Outlook drop and a plain-text version.
The email is cleaned before it is shown: scripts, forms, event handlers and frames are removed, and the preview is drawn in a sandboxed frame where nothing can run. Remote images and fonts are always blocked, and links do not open.
Everything stays in your browser. HTML up to 2 MB and .eml files up to 10 MB are read.
