If your open rates are falling, it’s time to revisit your email strategy. Audience preferences can change, so make sure your content is relevant and matches subscriber interests. Segmentation can help here—grouping subscribers by interests, past behaviors, or demographics allows you to send more targeted content. Personalizing your emails, even just with the subscriber’s name, can improve engagement. Experiment with different send times and days to find what works best for your audience. Regularly cleaning your list to remove inactive subscribers can also improve your open rate, as it ensures you’re engaging those who are genuinely interested in your emails.
