Please answer the following questions $($access the current situation; identify the problem areas; come with solutions$)$

What is Ty$-$D$-$Home's Net Promoter Score $($NPS$)?$

Is this NPS good? Bad? Average?

Because Alexander is able to identify each response as a specific customer $($by their e$-$m address$),$ and so tie that response to the information that he has in his customer databa he is able to perform much more specific analyses beyond the overall NPS $($calculated a answer to question $1).$ What further analyses should Alexander perform on the data he already collected? Please be specific.

What further follow$-$up research $($new$,$ more in$-$depth forms of research$),$ should Alexar undertake with these customers?

How might Alexander use the information gleaned from this process to increase his customer retention rates? Be specific about this and provide detailed suggestions $($Plec don't be vague like saying, $"$he should find a way to do better satisfy the customers."$)$
