Thanks a lot Alan for your reply. FUP is fair usage policy, how much data a user consumed in a fixed timeframe.
-- You can write if / then / else logic in FreeRADIUS
Would you be kind enough to provide an example or few lines on where exactly I can put this logic in freeradius?

What's a FUP limit?

You can write if / then / else logic in FreeRADIUS. And then run a script which sends email.

Even once an hour should be good enough.

It's up to you. I don't think it matters much either way. If you have decent indexes on the table, a SELECT of users with 80% utilization should take almost no resources.
And, you'll need to track which users got an email already. Which means writing that information to the DB. And you'll have to do this for both situations, above.
