Summary
What email marketers say9Marketer opinions
Email marketer from Email on Acid suggests testing email rendering across different email clients and devices, including Apple Mail. Ensure your email displays correctly and avoids triggering spam filters due to coding errors or broken elements, which can negatively impact open rates.
Email marketer from Mailjet explains that maintaining a good sender reputation is vital. This involves warming up your IP address, consistently sending valuable content, removing inactive subscribers, and promptly handling bounces and complaints to ensure better delivery to Apple domains.
Email marketer from GMass explains that personalizing emails with recipient-specific information can help bypass spam filters. Generic or mass-produced emails are more likely to be flagged as spam, while personalized messages demonstrate legitimacy and improve engagement, including with Apple domains.
Email marketer from Litmus warns about using spam trigger words in email subject lines and body copy. Avoiding phrases commonly associated with spam helps prevent emails from being filtered out by Apple's spam filters, improving deliverability and open rates.

Email marketer from Neil Patel's Blog explains that factors like sender reputation, authentication (SPF, DKIM, DMARC), content quality, and engagement rates significantly impact email deliverability to all domains, including Apple's. Poor practices in these areas can lead to bounces and low open rates.
Marketer from Email Geeks shares experience with a client having high soft bounce rates. They were responsive with the postmaster email, but the majority of bounces were due to users having over-capacity mailboxes, indicated by the 450 4.2.2 error.
