Litmus Scope is a free bookmarklet for creating web versions of emails for sharing.
Litmus Scope works for most web mail clients, such as Gmail. Litmus Scope is useful if you want to share an email design; it also has a code inspector for quickly seeing the magic behind the curtains.
It’s also useful for non-designers: you might want to share an email with many people without actually emailing them. Litmus Scope can also obscure your personal information in an instant, thereby making this app even more useful.
