Sumo, An email capture platform sends you this email after 2 weeks of becoming their "PAYING" customer to to make sure that the customer continues to pay them next month by offering help to capture email.
If they did not send this email & the new member had very few subscriber or none then they are most likely to cancel. This email also shows the customer that Sumo cares about them, so even if you had "0" subscriber, you will probably not cancel.
This is a good strategy to lower churn rate for new customers.
