You should ask your potential users this. Not with an email, but by sitting down with them and talking through the plan. You should have mockups for the flow.

You should ask your potential users this. Not with an email, but by sitting down with them and talking through the plan. You should have mockups for the flow. If they really like you, they'll say "OK, we're willing to try an A/B test on a small sample of users. When will it be live?" The big challenge with any kind of conversion rate improvement tool is that the difference it makes is only significant across large numbers of users. That means you have to target large companies, who tend to move slowly. Also, you have to make it easy to deploy and reliable. You'll probably need to give it away free to some medium-sized customers in order to get some data on the change in conversion rate.
