Improving email deliverability to Microsoft and avoiding spam filters involves a holistic approach encompassing technical configuration, sender reputation management, content optimization, and user engagement. Technical aspects include implementing SPF, DKIM, and DMARC for authentication and utilizing Microsoft's SNDS and JMRP for monitoring IP reputation and addressing user complaints. Sender reputation management requires proactively monitoring IP and domain reputation, cleaning email lists by removing inactive subscribers, and gradually warming up new IP addresses. Content should be engaging, personalized, and free of spam triggers, with links and image hosting scrutinized. Encouraging user engagement through segmentation and easy unsubscribe options is crucial. It's also important to be aware that services like Cloudflare, if hosting malicious content, can negatively impact deliverability. Finally, maintain low complaint rates, seek IP delisting if necessary, and prioritize a reputable ESP.
