What is the best way to get in touch with dropped-off users in 2021?
We have a certain funnel in our B2C app. It would be helpful if we could contact users and ask them directly what they like or dislike about the onboarding process or an app in general. Usually, I would ask them for an e-mail address and then write a letter, but it seems to me that response rates have dropped over time. Another way is to ask for a phone number and contact them in WhatsApp/other messaging apps. Or even ask for an Instagram username. How would you solve this problem for your business?
