The layout of your newsletter or email can have a significant impact on how your audience perceives and engages with your message. As such, you should strive to create a consistent and attractive layout that reflects your brand identity, supports your purpose, and appeals to your audience. When considering the font size, type, and color, opt for a legible and standard font such as Arial or Times New Roman with a size of 10 to 12 points. Additionally, limit the number of colors and fonts you use as too many can be distracting and unprofessional. Spacing and alignment should also be taken into consideration; single or 1.5 line spacing for text is ideal, as is leaving some white space between paragraphs and sections. Aligning text to the left or justifying it produces a neat and uniform look, whereas center or right alignment can make text harder to follow. Headings and subheadings are also important as they help organize information and make it easier for readers to scan the document. Use a larger font for headings and subheadings, making them descriptive and catchy (e.g., "What's new in our company" instead of "News"). Images and graphics can be used to illustrate points and add visual interest; however, ensure they are relevant, clear, high-quality, not too numerous or large, and have captions/alt text for accessibility/SEO purposes.
