Curious what people have found to be the most successful subject lines for cold emails. I have tried the following, ranked in order of effectiveness. Note, I am doing a regionally-focused search.

- Charlotte Local Interested in X
- Alex Gajewski Intro (Charlotte Connection)
- Hempstead Partners Intro (Charlotte Connection)

There wasn't much difference in effectiveness between Alex Gajewski Intro and Hempstead Partners Intro, but the former was slightly better. What have your most effective subject lines been for open rates?
