When a client entrusts us with the design of the graphic image of your company, within all the things that are usually designed such as stationery, design of the web and blog interface, business cards, etc ... the design of a newsletter or newsletter coupled to that graphic image if the company needs to get news and news about its products to its customers.
In Smashing Hub I have found a good compilation of 35 pretty creative newsletter templates that you can download and use directly or also use them to get ideas and inspiration to design your customer's newsletter.
Among the 35 newsletter templates you will find examples with different styles that you can customize and also different formats so that you do not always have to adapt to it, although it would be ideal for the client to be more or less clear about the type of newsletter they want and thus help you with the design.
