Guild Wars 2

I’ve found it a bit strange, and confusing, that in-game mails that are issued once per account, like the Wintersday Gift or Trading Post purchases, have no definitive icon or disclaimer that sets them apart from your other Character Specific mails. (All Wintersday mails use the personal story icon for mails and don’t mention the gifts are once per account)
This obviously gets confusing for new players, like me, when I got the Wintersday Gift mail but thought that each of my characters had got the same mail, each with their own items.
But it turns out this was a once off thing that, although visible in each character’s mailbox, the items were only available for one withdrawal.
I think emails like this,and Trading Post purchases and any other Arenanet announcements, that are once per account instead of per character, should be labelled as Account Mails to differentiate from Character Mails in the same way that items are Account Bound or Soulbound.

This would help new players, like me, from deleting items or characters, not knowing that the stuff we withdrew from mails would not be duplicated for our other characters.

No one else have this issue?
