It’s critical to test subject lines.
The goal of a subject line is to create curiosity about content, to entice your prospect to read it further.
Even the most experienced direct response marketer can guess wrong.
But the market place is never wrong.
Here is a test for an investment newsletter:
In Test #1:

• Why 94% of my stock recommendations made money.

In Test #2:

• How my picks made 22.92% when the S&P 500 lost nearly 19%.

Which do you think worked best?
If you picked No. 1 you are right. It got a 10.53% response rate, compared to a 6.8% for No. 2.
No. 1 got a 185% better result.
