It's a good idea to test the campaign's success along the way using the metrics you've established above. If you're not getting the click-throughs you would like, for example, try revising your subject line, lead-in, or even improving on your offer. The most important part of your strategy is having a clear sense of your objectives.
Each tool you use is a tactic; your plan should connect how each tactic delivers on each objective. Also, keep in mind that by far the two most important factors are your offer and the list you use. No matter how good your execution, you won't be able to sell email list lipstick to, for example, male basketball players.
