Several factors can contribute to poor email list quality:
Purchased Lists: Buying email lists often results in low-quality contacts who are not interested in your content. Outdated Information: Email addresses change over time; failing to update your list can lead to bounces. Improper Opt-Ins: Adding contacts without proper opt-in can lead to spam complaints and low engagement. Insufficient Segmentation: Failing to segment your list properly can result in irrelevant content being sent to recipients.
