A lot of copywriters have a hard time thinking of an eye-grabbing SL...
But it's actually easy to write once you know the "4-U's"
A good subject line must be
- Unique
- Ultra-specific
- Urgent
- Useful
Example:
"How I made $1,203 in 73 minutes"
Ultra-specific + Useful + Unique
If you're really struggling coming up with a good SL, don't really focus on the SL yet, focus on knowing the goal of your email and writing your email body. Then you should have a good subject line idea.
