According to a study by Mixpanel, only 17% of SaaS users are activated in the first week.If you offer a 7-day free trial, this means that 83% of the leads that join your trial will never experience the value of your product.

Instead of just cancelling their plan at the end of the trial, go ahead, and give them a little more time to use the product.

Most of the users may not have had to time to try your product. And if they have, giving them more time will deepen their experience with the product and  increase the dependency on it.
