Determine whether or not the promotion has specific, achievable goals; a vague promotion can confuse your audience and weaken your brand. Note how the effort will support your business goals: bringing in new customers, reinvigorating old customers or increasing awareness of a new product line, for example. Read the marketing materials to ensure that they have a clear message and call to action that will give customers an easy, logical next step. Look at the way the promotion is presented to your customers in terms of design, distribution and copy to see if it will inspire them to take the desired actions. Test it on a representative audience sample before sending it for production.
