Herald – Apple Mail Email Notification Plugin [Mac]

When it comes to mail notifiers that notify about the incoming mail, we have seen plenty of them in Windows. There are some standalone GMail Notifiers, Outlook Notification plugins, etc. But what about Mac?

Herald, unlike other notifiers, is a beautifully coded plugin for the Mac OS X email client called Apple Mail. Apple Mail(which is also called Mail.app) is an email client from Apple that is integrated in every Mac OS X operating system.

It is totally customizable. Once installed, you will get a pop-up alert every time a new mail arrives. The best thing about this plugin is that you can perform actions directly from within the notification dialog. Weather you want to View, Delete, Reply, or Mark it as Read, all options are given at the bottom of the notification dialog.

The message window is scrollable which means you can read the email without shifting to Apple Mail. Once read, you can then reply, delete, or perform some other actions. Below are some screenshots showing the General, Appearance, and Mailboxes tabs.

According to the developer Mail plugins are not officially supported by Apple, but Herald has been rigorously tested. Did I forget to mention that it groups all emails in a single notification window in order to reduce clutter? You can flip through them easily.

It works on Mac OS X 10.6 Snow Leopard. Enjoy!


  1. Hi. I have os x 10.6.8, I downloaded Herald, and tried to install it. It states it cannot work on my system because it requires 10.8 or newer. Anyone have suggestions? It states it works on 10.6 Snow Leopard, but I cannot get it to install. Any information would be greatly appreciated. Thanks!!

  2. Not clear at all how this works. Can it make notifications even if Mail is not launched? If not, whaza big deal? Mail already has sound notifications.

  3. From the looks of things I will be added to the list of satisfied customers. Thanks for this plugin

  4. Herald is great. I tried GrowlMail, and even though I like Growl, I didn’t like GrowlMail at all. Herald has a much better pop-up window, the toolbar is incredibly useful and well-designed, and the entire operation is smooth and easy.

  5. I have the same problem with 10.6.4 and Mail 4.3. We all kindly ask the author of Herald to make some fix.

  6. I just loaded mac os 10.6.4 and that means version 4.3 of mail I think, and it says that herald is no longer compatible. do you have a fix?


  7. I'm looking for alarms to continue to sound until the e-mail is acknowledged? Can Herald provide this feature?
