Preventing automated abuse requires a combination of best practices and technical solutions:
1. Use Double Opt-In: Ensure that subscribers confirm their subscription to verify their email address. 2. Implement DKIM, SPF, and DMARC: These email authentication protocols help verify the sender's identity and reduce spoofing. 3. Regularly Clean Email Lists: Remove inactive or invalid email addresses to maintain a healthy list. 4. Monitor Engagement: Track metrics such as open rates and click-through rates to identify suspicious activities. 5. Employ Anti-Spam Solutions: Use tools that detect and prevent spam and phishing attempts.
