What I want in macOS is what Apple doesn’t give to Mac users in Notification Center. The option to review and respond instantly to an email message without having to switch gears and open up or move to the Mail app.
Fortunately for the email impaired among us, there’s a Mac add-on that’s much like having Mail within a pop up window that only pops up when there’s incoming email. It’s called Herald and it’s free. A simple pop up comes with most of the tools you need to catch and respond to incoming email on the fly.
See? That looks just like a mini-email app, complete with From:, To:, Subject and a few paragraphs of the email text. What’s that on the bottom of the notification pop up window?
It’s the Quick Action Toolbar which lets you read, reply, delete and more without switching over to Mail. The whole shebang is customizable, too. Change the window size, color style, font, screen position, and even transparency right from the Preferences.
Preferences is where Herald shines. Not only can you adjust Herald’s notification window look and feel, but you control Herald’s action on a per mailbox basis, determine which email account gets notifications, and much more.
If you love settings then you’ll love using Herald because it’s as customizable as a Mac Mail utility can get.
Herald is a free plugin for Mail and while it works well, but every time Apple puts out a new version of Mail then Herald needs to be updated, too. That happens to Spam Sieve and many other Mac Mail plugins.
