To truly improve deliverability, focus on the following key factors:
1. Quality Content: Ensure your emails provide value to the recipients. High-quality, relevant content can increase engagement and reduce spam complaints. 2. Permission-Based Lists: Always use opt-in lists where recipients have explicitly given permission to receive emails from you. 3. List Hygiene: Regularly clean your email list to remove inactive or invalid email addresses. This helps maintain a healthy sender reputation. 4. Segmentation: Segment your audience based on demographics, behavior, or preferences to send more targeted and relevant emails.
