Greetings,
This thread takes us back to those days, where Call Centres were fun and responsibility.
Taking off from where Marianne left off, what matters is that the survey is conducted before the Caller recedes into a zone of indifference, which is what is more likely to happen once a need is attended to.
This time span varies with the service called for.
Given the fact that you are adopting the Mail process, the rough off the cuff time span within which a Customer Satisfaction Survey to a caller is received by the caller is within a week of the Call Resolution Time.
