The first part of the IIF function must evaluate to either True or False.
So, if "Range("C3").End(xlDown)" contains text the function fails.

Give this a try...
Dim addresses As String
Dim c As Range
For Each c In Range("C3", Cells(Rows.Count, 3).End(xlUp))
If addresses < "" Then
addresses = addresses & ", " & c.Value
Else
addresses = c.Value
End If
Next

it throws "Type Mismatch (13)" on the "for each" line only if the range is
strings, numbers work fine, but I need it to be strings

Dim addresses As String
For Each c In IIf(Range("C3").End(xlDown), Range("C3",
Range("C3").End(xlDown)), Range("C3"))
If addresses < "" Then
addresses = addresses & ", " & c.Value
Else
addresses = c.Value
End If
Next
