If your email marketing campaign isn’t delivering results, you may not be targeting the right audience. Segment your list and send personalized content based on subscriber interests. Another issue could be your subject lines—if they’re not engaging, people won’t open your emails. Test different subject lines to see what works best. The content of your emails also needs to be relevant and valuable. Ensure you’re providing content that your subscribers find helpful, entertaining, or informative, and include clear calls-to-action (CTAs) to drive engagement.
