You can also use Microsoft Office Frontpage, an HTML editor used by beginner and expert web developers in making websites. If you are well-versed with HTML scripts, you can make more advanced features with your HTML email and with the use of photo editing software, you can make your designs more sophisticated. However, using a large image format as the background is not advisable because it can make loading very slow. In making HTML emails, the content of your newsletters, brochures or flyers must be prioritized over the design. It is recommended you use only tables and plain color backgrounds instead of image backgrounds.
Insert only images that are relevant to your message, especially if you are endorsing a product. All images used in your HTML email must be uploaded to public online storage to prevent broken links. For example, if you are advertising a "house for sale" and you inserted that image from your "my documents" into your flyer template created in MS Frontpage, then you will surely have a broken link once you send it as an email. HTML does not directly copy the image as part of its whole body, instead it still follows the location where you browsed it. To do this correctly, you should store all your needed images in your public online storage and make sure to use the absolute URL of the image.
