This kind of initial research and analysis is incredibly important. If you include anything which you haven’t subjected to research, analysis, insights, experience, and expert opinion, it simply won’t fly. This is important. Everything these days has to be tailored very specifically to your brand and your personal customer experience. Your competitor might have an amazingly successful marketing strategy (and it's good to learn things from what they're doing!), but that doesn’t mean that the same kind of thing would be as successful for your brand.
Technology has a significant impact on consumers’ expectations, and those expectations impact how subscribers engage with your email marketing. Brands need to continually demonstrate that they know their customer, which can make it a challenge to stay on top of the evolving context of marketing. An email strategy can make all the difference between building a relationship with your customers and sinking without trace.
