Summary
When experiencing bounce errors from Apple domains, the initial step involves investigating the bounce errors through your Email Service Provider (ESP) to understand the specific reasons behind them. Verify that the bounces are actually originating from Apple and not misclassified by your ESP. Focus on maintaining a good sender reputation by checking your IP and domain reputation using available tools, properly authenticating your email with SPF, DKIM, and DMARC, and ensuring your reverse DNS records are correctly configured. Actively manage your email list by removing inactive or invalid addresses and honouring unsubscribe requests. Warm up your IP address gradually to build a positive sending history, and monitor engagement metrics like open rates and click-through rates to identify potential deliverability issues. Implement a DMARC policy to prevent domain spoofing. If necessary, reach out to Apple's support with detailed bounce information and a record of your sending practices after exhausting other troubleshooting steps.
