How to educate your customers with impartial information.
When your prospect is looking for information to help them make a decision, they will be attracted to valuable impartial information. By offering this information as a stream of emails, it will become collectable, and referred back to at a later stage.
Use the principles of information architecture to control the flow of information. The information you are providing will be based on one of your 'quality issues'; you are providing information to improve this quality issue in the prospect/customer.
Each email should refer to articles on your website that help to build trust and reduce anxiety. You can link the articles together by classifying them with the same theme. That way, when an article is displayed, the other articles will appear in the related links.
