iCloud does its own filtering with various techniques but, as you know, spam eventually finds its way into your mailbox. If you have some junk mail, you can mark it as junk simply by tapping on the message and then tapping the flag at the bottom and choosing the "Move to Junk" option. You can also do this with the Mail app on your Mac or in iCloud.com. This supposedly will ensure that future messages from that particular sender will go straight to junk. Unfortunately this has been extremely buggy recently and hasn't worked for everybody.
Rules are not only a great way to organize your iCloud email inbox, but also can be used as an effective spam filter. Rules are filters that you create that are applied to every incoming email, so you can have emails routed to your various folders, keeping your inbox uncluttered and your messages organized. Emails from your friends can go to their respective folders, messages about an upcoming vacation can go to a vacation folder, junk mail can go straight to trash, and so on. Rules are simple to set up, here's how:
1. Log into your iCloud account and go to your email. Click on the gear shaped icon in the lower left (this is the "Actions Menu") and click on "Rules."
2. The Rules window pops up. To make your first rule, click on "Add a rule" on the right hand side of the window. This brings up another small window, where you'll create the rule.
iCloud can be set as the default email address on the iPhone, iPad or iPod touch. This means when a new email is composed, it will automatically be sent from the @iCloud address chosen in the steps below. To start, make sure the iCloud account is active and iCloud email is set up on the device.
1. Navigate to Settings -> Mail, Contacts, Calendars -> Default Account.
An email alias is simply a forwarding email address - anything sent to it will be forwarded to your main email address. Aliases are useful for organizing your emails and managing spam. For example, you might want to use your real iCloud email address for emailing friends and family, but use an alias for registering on various websites. Then you know that anything sent to the alias has to do with things you've signed up for around the web, and it can be easily separated from your more important emails.
iCloud allows you to have up to three aliases. Here's how to create one:
1. Sign into your iCloud account, head to your email and click on the "Actions Menu," which is the gear shaped icon in the bottom left.
