Heya, Alex.

What is the context? Are you building a webmail client? Is this a messaging system for a forum site? Are you using a pre-built package/app, or did you write your own?

Heya, paitoon.

The way I generally do it is record the timestamp when a User 'reads' the message. That way, to determine which messages are unread, I simply search for entries where the read date is null.
