🤓 Tips for Maximizing Effectiveness

  1. Two-Step Collection:
    Start by requesting an email in the first step, then ask for a phone number in the second step. This minimizes the risk of lower email opt-in rates.

  2. Optimized Design:
    A clear and attractive design can significantly improve the conversion rate of your pop-ups.

  3. A/B Testing:
    Test different approaches to determine what works best for your audience.
