Start by identifying the primary goal of your email. Is it to announce a new product, share a piece of content, or promote a sale? Once you have a clear objective, everything in the email should support that goal. Use a compelling subject line that hints at the main message. The body of the email should be concise, visually appealing, and include a clear call-to-action (CTA). Use bullet points or short paragraphs to make the content easy to read.
