The CTA disclosure test: I added "$29/m after 5 messages" to every Free Trial button. Here's what I expected to happen.

Earlier this week I made a change I had been putting off for two months. I went through every "Start Free Trial" button on the site and rewrote it to read "Start Free Trial — $29/m after 5 messages". Same button, same color, same destination. Just a price tag glued onto the label. Then I sat back and waited for conversion to crater. That's what I expected. That is what most CRO people I trust have told me to expect over the years. Disclosing a price near the CTA is supposed to scare buyers off.
