Scott’s Gmail Alert 4 can do all of this for you, monitoring multiple Google Accounts and alerting you when something needs your attention. Each account can be assigned a different colour label so when an alert is displayed you can tell at a glance which account it relates to.
The appearance of alerts can be customized in terms of colour, size and transparency, and you can also opt to show an on-going message count so you always know the state of your inbox. A great feature of the program is the scheduling option. This can be used to change when Scott’s Gmail Alert 4 checks Google for new alerts – if there are times of the day when you would rather not be bombarded with alerts, you can configure these as quiet hours.
[advt]There are a number of programs that can be used to monitor Google Inboxes, but Scott’s Gmail Alert 4 takes things to the next level, supporting not only additional Google services but also multiple accounts. As an added bonus, the program can also be run from a USB drive so it can be used on any computer.
