As a modern marketer, email is at the heart of your online marketing efforts . . . so it's important to take the time to make sure that every aspect of your strategy is optimized. That's why I've developed a list of nine rules over the years that have proven themselves worthy across entrepreneurial startups, SMBs, and global enterprise organizations. (Just be sure to test these guidelines to determine which work best for your target audience.)
1. ALWAYS take into account local time when sending emails. The best times to send are 9:00 a.m., 3:00 p.m., and 4:00 p.m.
2. NEVER be verbose in email body copy. Keep your text to 145 words or less.
3. ALWAYS use the "curve" method when writing an email subject line: Play on curiosity, urgency, relevance, value, and emotion.
4. ALWAYS keep your email subject lines to 50 characters or less.
5. NEVER send more than one email to your recipients per day.
6. ALWAYS use a good aesthetic mix of images and text in your design. A good rule of thumb is one image for every 15 lines of copy.
7. NEVER cheat and use "FW:" to imply that the email has come from a trusted source.
8. NEVER put the unsubscribe button or link at the top of an email.
9. NEVER send an email without proofreading or testing.
