Email notifier!

Were you able to locate a good working email notifier that works with few differing email providers (incl. few email accounts from one email provider), and access via the notifier directly your email accounts.

I am using dynadvance Notifier, despite claiming that they can list all email accounts
from various email providers. HOWEever, it doesnt list my gmail accounts, and does only notify me on my yahoo that is the first listed account, for the others I dont get any email notification!

What were your user experiences on features/functionality; freeware/value for money?

Which email provider are you actually using, and why?
