Summary
Addressing spikes in user-reported spam rates and improving IP reputation requires a holistic approach encompassing technical setup, list management, content strategy, and continuous monitoring. A key aspect is understanding whether spam rate spikes are normal fluctuations or indicative of underlying problems. Fundamental steps include email authentication (SPF, DKIM, DMARC), maintaining a clean and engaged email list through regular cleaning, segmentation, and double opt-in, providing valuable and relevant content with easy unsubscribe options, and actively monitoring deliverability metrics and sender reputation. Feedback loops play a crucial role in identifying problem areas and enabling targeted corrective actions.
