A well-formulated hypothesis should be specific, measurable, and actionable. Here are some key components:
Specific: Clearly define what you are testing. Example: “Changing the subject line will increase open rates.” Measurable: Define the metrics to measure success. Example: “We expect a 10% increase in open rates.” Actionable: Ensure the hypothesis can be tested. Example: “We will use A/B testing to compare subject lines A and B.”
