Encourage people to invest time and money in your online course by sending consistent emails with captivating subject lines that prompt them to start a 7-day trial. For instance, social media influencer Deepak Kanakaraju uses subject lines such as "Myths about blogging and how to overcome them" and "Three reasons to enroll in the 100-day blogging video course" for his blogging course newsletters. These enticing subject lines are hard to resist.

Once you’ve captured their attention, develop content that motivates them to enroll in the course. Regularly send emails highlighting the benefits of registration to pique their interest. Address their concerns and reassure them that your course will meet their needs. Identify your ideal subscribers and tailor your outreach to target them effectively.

Personalizing your emails will give your audience the impression that your course is designed specifically for them. For example, if you offer an IELTS preparation course, which is essential for admission to many international universities, you might address common myths about the exam or send an email with a subject like "Tips for IELTS Preparation for Busy Professionals." This approach is effective because it directly addresses the challenges faced by working professionals who struggle to find time for exam preparation.

Monitor how recipients engage with your emails—whether they open them or click on links and attachments. You can then retarget those who have interacted with your emails but haven’t yet enrolled in the course. These individuals are promising leads and may benefit from persuasive follow-ups.
