Summary
Apple email bounces can stem from a wide array of issues, including hard bounces (invalid addresses), soft bounces (full inboxes or server issues), Apple's filtering policies, spam traps, content triggers, and IP reputation. Solutions involve cleaning email lists, verifying addresses, setting up feedback loops, monitoring IP reputation, ensuring proper email authentication (SPF, DKIM, DMARC), and using email testing tools. Proofpoint, as a filtering tool for Apple, and the Apple Postmaster should be checked for blocks. Bounce messages (NDRs/DSNs) provide status codes to help diagnose the reason for failure. Overall, proactive monitoring and a focus on maintaining a strong sender reputation are essential.
Key findings
- Bounce Causes: Bounces result from both temporary and permanent issues like invalid addresses, full inboxes, spam content, and poor IP reputation.
- Apple Specifics: Apple uses Proofpoint for filtering, has stricter policies, and its postmaster can be contacted for resolution.
- Authentication: Properly configured SPF, DKIM, and DMARC are crucial to prevent authentication failures.
- Sender Reputation: Maintaining a good sender reputation is vital to avoid bounces and being marked as spam.
- List Hygiene: Regular list cleaning to remove invalid or inactive addresses reduces bounces and improves engagement.
- Tools and Monitoring: Email testing tools and Google Postmaster Tools can help identify deliverability issues.
Key considerations
- Proactive Monitoring: Continuously monitor email practices and sender reputation to identify and address issues early.
- Authentication Standards: Adhere to email authentication standards (SPF, DKIM, DMARC) to improve email deliverability.
- Verification Services: Use email verification services to remove invalid and risky addresses before sending campaigns.
- Feedback Loops: Set up feedback loops to receive reports on spam complaints and address issues.
- Content Review: Review email content for spam triggers and avoid using excessive links or specific words.
- IP Reputation management: If on a shared IP, monitor your IP's reputation, and if you have high volume consider a dedicated IP.
