If this isn’t the cure for email fatigue that you’ve been looking for, then it must come a hair shy of being it. MailSlayer is a browser extension that can take Gmail as you know and love it, and add a series of apps on top of it that will let you start managing all your messages easier than ever.
There are three of these apps: “Notes”, “Snippets” and “Personal Labels”. In general, the “Notes” app lets users add notes to all the emails and threads on their inboxes, while the “Snippets” app makes for typing emails much faster by using and reusing frequent snippets. It’s a bit like using templates, if you will.
For its part, the “Personal Labels” app does pretty much what its name suggests: applying automatic labels to emails, and have them sorted by importance for you according to who the sender is, and the subjects that are being discussed.
These apps are available both for Firefox and Chrome, and they are all bought separately. Each costs $5, and a bundle is likewise offered, letting you get all three apps for just $12 per month.
