If for example the validation would require trying to apply patches on
top of another branch in a temp repository, you would need to know the
number of patches and be able to determine whether you need to reset the
branch (patch 1/N) before applying. For that you would need to parse the
contents of the patches. This is not the end of the world but I assumed
that it would be easier to handle with a hook that fires once with all
patch files.

Another option would be to change sendemail-validate to be called only
once with all patches. That would be the ideal solution since the
existing hook is not always usable with series. But that would be
a breaking change. I personally don't mind a small breakage like this
but I don't know what is the project's policy.
