Email Discount Effectiveness

Have you seen this question before?

Let’s say you work at a company like Dropbox. The email marketing team is trying to increase revenue from existing users that sign up on the free tier.

The email team has an idea to include a 20% off discount for the first month in an email campaign some X number of days after a user has signed up.

How would you determine if this discount email campaign would be effective or not in terms of increasing revenue?
