No, there is no indication on the outside of the ballot.
While mail in is riddled with fraud, in my county they seem to have their shit together. I opted for mail in ballots and when I sent my registration in I was actually called because my signature did not match 100%. They sent me a new registration and I resigned it.
Then after I vote and mail it I can check to see that it was received and what my vote was.
