This flow gets right to the point, which reduces friction and increases the chances of getting a review.
As depicted in the diagram below customers are sent an initial review request.
If they post a review that is the end of the flow.
If they don’t post a review after the initial request they are sent a follow up review request a few days later.
The direct flow will contact the customer, at most, twice.
At any point in the flow, regardless of the contact method, the customer can use the unsubscribe link to stop receiving any further requests.
