Emails sent to Apple domains (icloud.com, me.com, mac.com) can experience lower open rates and increased bounce rates due to a multifaceted set of issues. Key contributing factors include strict spam filtering, inflated open rates due to Apple's Mail Privacy Protection (MPP), sender reputation problems, improper email authentication (SPF, DKIM, DMARC), sending to over-capacity mailboxes, sudden spikes in email volume, inadequate list hygiene, use of spam trigger words, lack of personalization, and technical rendering issues. Remediation strategies encompass maintaining a strong sender reputation, employing proper authentication methods, regularly cleaning email lists, gradually increasing sending volume, personalizing email content, avoiding spam trigger words, testing rendering across various clients, monitoring SMTP bounce codes, adhering to Apple's technical requirements, checking blocklists, and facilitating easy unsubscription.
