Selection of email templates for email marketing campaigns

Hi, we are looking for a selection of email templates suitable for marketing to a database of 3,000 customers, using the software platform 'Sendinblue' We need the templates to be clean, professional & with a consistent nice color scheme,but also quick to load and easy on the eyes as our clients are mostly between the ages of 40-80 years old. I have attached 2 very very rough examples of something we are after, but you can modify them to however you please. We basically need a template thats solely devoted to product advertising with minimal text / info, and also another with mainly text (sort of a newsletter) with other spaces to be utilised for product placement / advertising. I have provided our logo to be used, however thats all I have provided in the way of images. You can put whatever images you want in the template, as we will edit them to suit our products. Main points; 1a. Sendinblue is the platform used for our email marketing. We are able to give you access to this dashboard. Our store platform is powered by Bigcommerce. 1b. These templates need to be consistent with eachother. 2. They need to be able to be edited by HTML or in the Sendinblue dashboard. 3. We'd like a color scheme consistent with our logo 4. We need a few styles of templates to choose from. 5. The mock templates I provided in fiverr are extremely rough examples and we do not want you to copy them, it is literally just a rough example of what we want in an email template. Some facts about our business: Australia based. We sell engineering tools & special purpose tooling such as taps, dies, reamers, lathes & mills and tooling to suit these machines, etc etc. Our clients are mostly older males.
