When defining objectives for your email campaigns, use the SMART criteria:
Specific: Define clear and specific goals. For example, instead of "increase sales," aim for "increase sales by 20% in three months." Measurable: Ensure that your objectives can be measured. Use metrics like open rates, click-through rates, and conversion rates. Achievable: Set realistic goals that are attainable given your resources and constraints. Relevant: Align your objectives with your overall business goals. Time-bound: Set a clear timeframe for achieving your objectives.
