Perfect mail notification extension, does exactly what is promised certainly when you contribute an amount you will have this fixed on most browsers.

I've been using this extension for years, always been happy with is.

One feature request: I would like to have the ability to have an email account added, but for it not to include emails from that account added in the little red number. (I have my wife's email accounts added on the desktop, but I don't need a running tally of how many emails she has unread, and I don't want to be bothering her and telling her to clean out her email accounts.)

I have been using this add-on for close to one year now and it has been a lifesaver when I am waiting for a reply knowing when it arrives. EXCELLENT! Highly recommended.

I just realized I've been using this addon since 2011? 2012? It's been a massive amount of time, and it's still one of the first I install when setting up a new browser.

I can't recall ever having an issue, it's rock solid and works perfectly for how I use email.

I monitor 9 diff. email addresses from Checker Plus. Nothing better.

Unobtrusive and easy to use, this add-on has really helped me be more mindful of my messages. I'm easily distracted and the fact that there is a built-in reminder via the 'Repeat Notification' function is wonderful. The UI is easy to navigate and the customization options are near endless, so you can easily match Checker to any other themes you might be using. The only problem I ran into was with upgrading (which was entirely on my end), so I reached out about it and got a super fast feedback message from Jason that sorted things out immediately (Thanks again for that!)

I'd 100% recommend this add-on to anyone, but especially to people like me that are more accustomed to Discord and Steam style desktop message notifications and looking for a similar interface.
