Launch with refundable accountability money
If you lack the credibility to charge for v1, use refundable accountability money instead of a real price. Collect $50 into a pot, refund anyone who completes the challenge, donate the rest.

The unlock isn't 'send less' — it's 'earn the right to send more' by personalizing. Click-through rate is the proxy for relevance: when CTR is high, opt-out pressure stays low and you can scale frequency without burning the audience.
