Sending the same type of email every week can make your list lose interest quickly. To avoid that, you can switch between different email styles. For example, one week can be a story or behind-the-scenes update, another can share tips, and the next can highlight a customer review or success story. Changing the layout and tone a little helps your audience stay interested. You can also keep a small content plan that tracks what you've sent before. That way, you can spot repetition before it happens. What type of email content do you think keeps people opening messages again and again?
