does what it says on the tin. it notifies you when you have unread emails. HOWEVER, recently there was an update that locked MANY previously free features behind a $20 USD paywall (despite the fact that the popup CLAIMS you can donate ANY amount, i guess $19 and lower doesn't count as any).
These features aren't anything advanced either, any and all customization, changing what buttons appear on the popup, the works. Way shittier add-on. Use only as a notification bell that opens gmail and nothing else.

Good addon but leaving the placeholders for premium only features in menus is a dick move. Promptly removed.

This is a good extension! I would definitely recommend it, but I have to complain. Why are you expecting us to donate just to get extra features that shouldn't even be put behind a paywall? I know you want people to donate, but don't put simple things such as themes and being able show or hide specific buttons behind a paywall, it's just not worth it. I would only put the more advanced features behind the paywall. (Also I'm rating this one star since it seems like the dev doesn't want to reply to anyone.)

:D

Works perfectly, it's really helpful having multiple accounts and being able to mark read/unread/delete is convenient

I love this extension

This addon cannot count the unread emails in my gmail account, always display the wrong number.

This extension is the only reason I'm on top of my emails. Sometimes a little buggy (no longer syncs if I read/deleted an email properly) but still excellent at keeping me up to date on my inboxes.
