- Opt-in processes: Implementing clear and often double opt-in processes is recommended to ensure subscribers genuinely want to receive emails, thus reducing spam complaints and improving overall list quality.
- Monitoring vital metrics: Regularly checking metrics such as open rates, click-through rates, bounce rates, and complaint rates is essential for marketers to gauge performance and identify potential issues early on.
Key considerations
- Gradual ramp-up: New senders or those recovering from deliverability issues should warm up their IPs and domains gradually, increasing sending volume over time to build a positive reputation with ISPs.
- Understanding basic technicals: While not all marketers need to be deeply technical, a basic understanding of authentication protocols like SPF, DKIM, and DMARC is becoming increasingly important. For a simpler explanation, see a simple guide to DMARC, SPF, and DKIM.
- Subscriber feedback: Paying attention to feedback loops (spam complaints, unsubscribes) and adjusting sending practices accordingly is vital. Marketers should make it easy for subscribers to manage their preferences or unsubscribe.
- Holistic approach: Email deliverability is not a one-time fix but an ongoing process that requires continuous attention to list quality, content, sending patterns, and technical setup. Marketers should aim for a comprehensive approach to increase email deliverability.
