for the query below should I be using CFQUERYPARAM?

The ClientStatusID will not be a variable. it will always be as shown.

SELECT     m.IMailID, m.ClientID, m.EnvelopeImagePath, m.EnvelopeImageStatus, m.EnvelopeImageName, u.UserID, u.FirstName, u.LastName, u.UserEmail,
                      m.EnvelopeAlertDate ,(select count(*) from imail.tblIMail where ClientID = u.ClientID) as documentCount, c.ClientStatusID
FROM         imail.tblIMail AS m INNER JOIN
                      imail.tblClients AS c ON m.ClientID = c.ClientID INNER JOIN
                      imail.tblUsers AS u ON c.ClientID = u.ClientID
WHERE  (c.ClientStatusID = 1 or c.ClientStatusID = 2)
                   FROM imail.tbliMailActions act
                   where act.UserID  = u.UserID
                              and act.IMailID = m.IMailID)

well I would be using <cfqueryparam to prevent the sql injection and security purposes

You only need to use cfqueryparam when the query uses variable or user supplied input. If neither of those are true, you don't need cfqueryparam.

>> WHERE  (c.ClientStatusID = 1 or c.ClientStatusID = 2)

Having absolutely nothing to do with your question ;-) you could increase readability by rewriting it as:

     WHERE  c.ClientStatusID IN (1,2)
Understanding Web Applications

Without even knowing it, most of us are using web applications on a daily basis. Gmail and Yahoo email, Twitter, Facebook, and eBay are used by most of us daily—and they are web applications. We often confuse these web applications tools for websites.  So, what is the difference?

The primary reasons for using it are
A) performance/caching
B) defense against sql injection
C) data type checking

I used to do it myself, but then discovered there's no benefit with constants.
A) If the values don't change the db will cache the query plan without cfqueryparam's help
B) Since they're not user supplied, there's nothing to defend against. Unless it's yourself. But then you've got bigger problems than cfqueryparam can fix.
C) Doesn't apply with constants

good set of rules. I shouldn't have any more doubts. :)
