Unless you can show us a screenshot, I am unsure. There are several possibilities
- The token Lead Owner Email Address was used and your email was in the default.
- You used an alias email address, which only goes to other people.
- You did not save the draft, so the old version went out with #1 above.
Thanks for your response. I realized I did NOT deactivate the dynamic "FROM" field when I deployed it. My email address was just in as a default. So that solves the mystery!
