  Let $G \curvearrowright A$ be an action of a discrete group on a unital
$C^*$-algebra by $*$-automorphisms. In this note, we give two sufficient
dynamical conditions for the $C^*$-inclusion $A \subseteq A \rtimes_r G$ to be
norming in the sense of Pop, Sinclair, and Smith. As a consequence of our
results, when $A$ is separable or simple, the inclusion $A \subseteq A
\rtimes_r G$ is norming provided it has a unique pseudo-expectation in the
sense of Pitts.
