Many people who sign up to use your product will not be fully aware of the value it can provide. Ensure these people do not become lapsed users simply because they don’t understand what your product can do for them by sending a tutorial email. Asana designed their tutorial email to teach users how to use the product in their projects and maximize their productivity. While you should include multiple resources that display the full power of your product, focus on the one thing users must do to understand the value of your product.
