Find things that encourage people to engage. By tracking the statistics on each of your emails, you'll be able to develop concise reports about what works and what doesn't for your target audience. Take note of the specific days and times for your highest open and conversion rates. Test different tones and subject lines and see what causes your audience to read the blast. Stick to the things that your consumer tends to favor or enjoy and avoid repeating aspects of emails that do poorly according to the stats.
The primary cost of poorly crafted or mis-targeted emails is lost business opportunities, though in extreme cases it can damage a firm’s reputation as well. But the potential payoff for effective email marketing is substantial; email messages are more likely to be seen and acted upon by decision makers than online content, social media, or advertising.
