You have drafted a marketing strategy, which you need to show in your design and content of the emails you send out. Any corporate design you have needs to be shown in the email to help gain brand awareness.
The recipient needs to connect your site with the emails. They also need to separate it from any competitor. Always put the company image and logo in the email. If these interact properly you gain sales.
An email that does not show the corporate logo and design can have a downward effect in your business success. The image could be damaged too.
