Automatically Forward Apple iCloud Messages
You can have all your iCloud Mail messages forwarded automatically to another email account.
Automatically forward emails (all)
- In Mail on iCloud.com, click the Settings button in the Mailboxes list to open the Preferences pane.
- In the General tab, select “Forward my email to,” then type the forwarding address in the text field.
- If you don’t want to store a copy of each forwarded message in iCloud, select “Delete messages after forwarding. Keep in mind that storing copies of forwarded messages decreases your available iCloud storage space.
- Click Done.
You can also create a filter to forward only specific emails to your Parsio Mailbox.
