Think about how you’re getting your opt-ins. Using a series of smaller commitments, instead of one large one, can be more efficacious, as it plays into a user’s sense of self-identity. For example, you could try asking small questions, like the old sales technique of getting a customer to start saying yes. Instead of just asking for a user’s email address right away, ask if they’re interested in looking around, then follow that with a prompt to see more content, then follow that with a request for their email.
