Desktop email notifier

Please direct me to the correct forum. Nothing seemed to apply.

I have several Pop3 email accounts set up in Apple Mail...genealogy, business, bills, family, etc.

My email client is GoDaddy and they provide a webmail desktop notifier which is OK.

But, even though it says you can add up to 10 accounts, only five actually work.

I find it handy to glance up and see how many mails are new.

It's a lot easier than getting account info for each account in Apple Mail.

I've spent a few hours searching for something that would work, but almost anything that looks useful is for Windows.

I have looked through the app store, too.

Any suggestions?

Thank you,
