Pop-ups and Welcome Series Flows in Web Development
Pop-ups and welcome series flows are commonly used in web development to engage users and guide them through a specific process. The day these features should be live depends on the purpose and strategy of the website. For example, if a website wants to collect email addresses through a pop-up, it is typically best to have it live from the moment the website launches. On the other hand, a welcome series flow, which is a sequence of emails designed to onboard new users, should be live as soon as the user signs up. Timing and coordination are crucial to ensuring that these features work effectively.
