sequence - How to approach sequential classification problem?

Question

I'm doing a case study for a company (X). While the data is quite expansive, contains attempts to promote/sell product to customers of company X. The marketing is done through 3 channels: by email, phone and mail. The focus of our study is to explain the conversion based on the attempts made through these three channels. The conversion is a dummy variable and the attempts of contacts are:

Customer	Cust Obs	Attempt	Attempt Sequence	Conversion
1	1	Tel	Tel	0
1	2	Email	Tel & Email	0
1	3	Email	Tel & Email & Email	1
2	1	Mail	Mail	0
2	2	Tel	Mail & Tel	0
3	1	Tel	Tel	0
3	2	Email	Tel & Email	1
