The problem email
Possibilities of replacing their existing process with your product. This email should focus on educating readers on the problems associated with their current method and should barely mention your product.
The benefit email
A look at the benefits of using a product like yours to achieve their goals. This email should focus on the benefits of using your category of product (I.e. using email marketing tools over mass-mailing from Gmail) and outline how doing so can help improve their lives.
The transition email
Remember, every potential customer is currently using something else to do what your product could do for them, and the act of switching from that process to using your product is a barrier you need to overcome. This email should focus on outlining a simple and easy process for making the switch from their existing solution to using your product to solve their problem.
The tools email
An overview of the tools available to achieve what your product achieves, almost like a quick buyer’s guide. This is the first time you introduce your product and outline why it’s superior to your competition. Include a call to action to purchase or sign up for your product for the first time in this email.
The case study email
A case study on how one of your customers uses your product. Make sure to outline what problems it solves for them (tied to the problems outlined in the first email) and what benefits it brings them (tied to the benefits outlined in the second email). Include a testimonial from a customer and a call to action to signup for your free trial/free plan in this email.
The resources email
The final email. Suggest some other eBooks, blogs, templates, kits, etc. for learning more about whatever it is your product does. You can also try including a discount code or special offer in this email as if you haven’t converted them from the previous emails a special offer could help tip them over the edge.
