Evaluate the effectiveness of using emojis in subject lines to increase open rates. Research popular emojis that align with your [Product] or [Service] and experiment with their placement in subject lines. For instance, test a subject line like “🎉 [Product] Offer – Don't Miss Out!” versus a more traditional one like “[Product] Offer – Last Chance!” Compare results for open rates and engagement across different demographics, such as [Role] or [Region]. Analyze whether emojis are more effective for certain types of campaigns, such as promotional offers or event invitations. Provide insights on when and where emojis can be most effective in email subject lines.
