iCloud email does count toward your storage limit.
The primary advantages I've seen for iCloud versus other providers are:
- push email on Mac and iOS devices
- Checkbox set up on OS X and iOS (better integration with Apple hardware)
- True IMAP solution (folders vice labels) - others could see this as a disadvantage and I'd understand
- Integration across the web and client side for contacts
- Can be configured on any IMAP client on any platform (Android, Windows, Linux, etc)
-
- If you like the domain (I still use my
xxx@mac.com address from years ago) - also have
XXX@me.com and
xxx@icloud.com
- Web site is pretty simple and clean
- No ads
- Use of aliases to hide your primary address for online stuff
There are disadvantages as well:
- Silent filtering of emails occasionally means you may never receive/be able to send...the forums are full of these discussions
- Lack of robust filters on the web side, lack of consistency (i.e. Mail on OS X has robust filtering, but is client based; no filters for iOS)
- Mailbox counts are not synched, until a push/pull is done for new emails. This is by design, IMHO...Gmail app for iOS, does sync read/unread, but keeps a persistent connection - which can have a battery impact.
- 5GB storage limit, including everything else (I pay $40/year for 25GB, so not an issue, as I only keep about 1GB of mail).
I will say, what one person may see as a plus, another may see as a minus. These are the big ones off the top of my head.
