To measure the success of your teasers, you should track key metrics that reflect engagement and conversion:
Open Rates: A compelling teaser in the subject line can lead to higher open rates. Click-Through Rates: Teasers should drive clicks to your website or landing page. Conversion Rates: Ultimately, the goal of a teaser is to convert the recipient, whether that means making a purchase, signing up for an event, or another desired action.
Use A/B testing to experiment with different teaser approaches and identify which ones resonate best with your audience.
