We went from thirty to seven and both the things I expected to get worse got better, which I did not predict.
What actually happened:
Activation went up. With thirty days people intend to look at it properly later and later never arrives. With seven, they either do it now or they leave — and it turns out doing it now is the version where they succeed. Urgency is doing real work here, not manipulation.
Conversion rate went up, largely because of the above.
Support load went up, and this is the cost nobody warns you about. People who are actually trying, in a compressed window, ask questions. That was a good trade for us but it is real work and it arrives immediately.
Absolute signups dropped slightly. Some people bounce off a short trial. Almost all of them were in the never-activated group.
The thing I would do differently: change one thing. You already know this from your pricing-page mistake, and the temptation to bundle changes is enormous because each one is small. Give it four weeks with nothing else moving.
And measure the funnel, not the outcome — signups, activated, converted. Conversion alone cannot tell you whether a change helped people start or helped people decide, and those need completely different follow-ups.
