I don't speak for GoDaddy @Ashu2008 but Sezzle is fairly new (2016?). It seems like daily there is a new payment service method and seemingly equally as often these companies go away or fall out of favor. I trust GoDaddy and that trust extends to companies in which they work with, providing services to me as a customer.
I'm not sure when or if GoDaddy will embrace any specific company but I feel assured that they will do due diligence in selecting service partners. Other than that, I can offer nothing. FYI if you hear that GoDaddy will have a relationship with a company then buy that company's stock!
