Thanks! I'll have to pay attention when I get my ballot (in OR it mail only voting here), never occurred to me to see what can be determined before opening the envelope, although I'm sure it varies by state.
too bad this doesn't have data before 2020, particularly 2016. 2020 had unusually high early/mail voting due to COVID-19 so it's hard to compare meaningfully

We usually see a summary through Simon Rosenberg's Hopium site at https://www.hopiumchronicles.com/
We also found later that @electproject.bsky.social at U Florida has a tracker too:
