Formulating a hypothesis involves identifying a specific question or problem you want to address. For example, you might hypothesize that a personalized subject line will result in higher open rates compared to a generic one. Your hypothesis should be clear and testable. Here are some steps to formulate a hypothesis:
1. Identify the variable you want to test (e.g., subject line, email design). 2. Develop a clear and concise statement (e.g., “Personalized subject lines result in higher open rates”). 3. Define the _metrics_ you will use to measure success (e.g., open rate, click-through rate).
