The "custom" email address is great.
The relatively recent inclusion of IMAP service in the base package is great (they used to charge extra for it).
THEIR UNCONTROLLABLE SPAM FILTER MAKES THEIR SERVICE A HAZARD TO USE.
90% of the email they sort into the spam folder is email I want to see. I flag them all as "Not Spam" and white list the senders, but to no avail.
Having to go rummage through everything in the spam folder is worse than having it in my in box. I still have to look at it, but it is an extra step I must remember to take.
Other than pretending to whitelist senders, they offer no other controls over the spam filter. I would turn it completely off if I could, but I can't.
DON'T USE THIS SERVICE IF SEEING YOUR EMAIL IS IMPORTANT TO YOU.
