Email marketing is not only about creating and sending emails, but also following best practices that ensure your emails are delivered, opened, and acted upon. For example, it's essential to build your list organically and ethically, without buying or renting email addresses. Additionally, you must comply with the relevant laws and regulations, such as the CAN-SPAM Act or the GDPR. You should also use a reputable email service provider that ensures your emails are not marked as spam or blocked. Furthermore, when crafting your emails, make sure to write clear and engaging subject lines and preheaders that entice your subscribers to open them. Additionally, design responsive and attractive emails that look good on any device and browser. Moreover, write concise and compelling copy that delivers value and solves your subscribers' problems. Lastly, include clear and strong calls to action that tell your subscribers what to do next as well as provide easy and visible options for them to unsubscribe or manage their preferences. Finally, track and analyze your email metrics, such as open rate, click rate, bounce rate, or conversion rate.
