# Avoid iCloud's Spam Folder

# Avoid iCloud's Spam Folder

Apple's mail infrastructure guards `@icloud.com`, `@me.com`, and `@mac.com` mailboxes using aggressive filtering technology focused on sender authentication, privacy, and content reputation.

## Apple Postmaster Guidelines

1. **Strict SPF and DKIM Alignment**: Apple requires all bulk senders to have verified SPF records and valid DKIM keys.
2. **Reverse DNS (PTR)**: Mail must originate from IP addresses with valid reverse DNS lookups that resolve to the sending hostname. Mailofly configures this automatically.
3. **Handle Apple Private Email Relay Properly**: Apple users who authenticate via "Sign in with Apple" may use private relay addresses (`@privaterelay.appleid.com`). See our [Apple Private Relay Guide](/guides/deliverability/sending-to-apple-private-relay) for specific SPF registration rules.
4. **Remove Unsubscribes Immediately**: Apple users expect instant opt-out compliance. Mailofly processes unsubscribes in real-time.
