All three have a part - an important part.  Authentication gets you to

Authentication: yes.
Reputation: yes.

Accreditation: why would I care?

By this I mean: can you give an example of how this would change my
opinion based on their reputation?

Very small senders won't have the volume to create a statistically significant reputation. But if they are accredited ("this is a shoe shop, established in 1985, uses good practices") and the reputation data is essentially empty, then you know something.

If you just have empty reputation without accreditation you don't know if they are new, and potentially churning identities, or just small.
