The email contains a prominent "Start Free Trial" button. If 500 recipients click this button, the campaign has a 5% CTR (500 clicks ÷ 10,000 impressions × 100). The marketing team notices that emails sent on Tuesdays with personalized subject lines consistently achieve a 7-8% CTR, while generic emails sent on weekends only reach 2-3%.
