Quality is better than quantity. Less is more in terms of email, or posts. Be brief and do not send too many emails, or make too many posts because it decreases the quality of them.
Conservative composition and sending ensures your messages are read. No one reads long emails completely and people who send too many emails get ignored. If your email is not read it is low quality no matter how well you wrote it.
Receiving relevant information via email can help you make better decisions in your life. It empowers you because knowledge is power. The more you have the more powerful you are.
For example, an email from your favorite store may include a coupon that can save you a lot of money on your next purchase that you would have made anyway.
Whether it's a big ticket item or small one, the money you save gives you greater spending power because you can buy additional items. Therefore, be liberal in email you receive by signing up for newsletters, mailing lists, and getting status updates from friends because it can help you make better decisions in your life. Be Conservative in email you send to protect your online image.
Remember! Brevity is the soul of wit!
