Even though it is perfectly acceptable and is a common practice to use the 8_stage classic model for the e_marketing plan as well, you might want to consider the simplified version proposed by Chaffey, who identifies four major steps to build the e_marketing plan:
Pricing _ I once said in my Marketing Plan Breakthrough S6PEC that, "Price is the key determinants of your profits". I stand firm to keep it that way. In your marketing plan, you will address pricing plan for your distributors, customers, multiple segments (some business charge differently _ price discrimination) and cost price i.e. your raw materials and things like that. Not many address price correctly and bear in my mind that we need to standby few pricing plan to respond to the market. Take for example during festive season, if everyone is lowering price and slashed their price or even ignited a price war, what do you do about that? Follow suit or wait? If you want to follow, how far? If you want to wait, how long? You capture all this in pricing plan.
