Timing of the Send: The specific time and day when an email is sent can make a significant difference. Studies show that emails sent on Tuesdays and Thursdays generally perform better. Frequency: Sending emails too frequently can lead to burnout and increased unsubscribe rates, while infrequent emails might make customers forget about your brand. Response Time: Quick responses to customer inquiries or actions (like downloading a resource) can enhance customer satisfaction and engagement. Campaign Duration: The length of time a campaign runs should be carefully planned to maintain interest without causing fatigue. Seasonal Timing: Aligning email campaigns with seasonal trends or holidays can boost relevance and engagement.
