Must have. Rated 5 out of 5 stars

I'm using this since ~1,5 years now. Never got a single problem. Works perfect for me, I get notified about important mails sorted into a special folder only. No more distraction by notifications about low-priority mails. :-)

Rated 5 out of 5 stars

I always searched for a way to get informed when getting high-priority mails within a specific folder, filled by filters. The folder based alerts provided by Mailbox Alert are just perfect. 5 stars.
