Conducting a subject line test typically involves A/B testing, where you split your audience into two groups. Each group receives the same email but with different subject lines. Here are the steps:
1. _Select a Variable_: Choose one element to test, such as length or tone. 2. _Create Variations_: Develop two different subject lines focusing on that variable. 3. _Split Your List_: Divide your email list into two groups randomly. 4. _Send Emails_: Distribute the emails with different subject lines to each group. 5. _Measure Results_: Track open rates, click-through rates, and other relevant metrics. 6. _Analyze Performance_: Determine which subject line performed better and why.
