Mail Strike....
That feature is enabled after a certain amount of time passed and hours played has been achieved.
I’m sure you will be able to send items within a week or two, as long as you both are playing somewhat regularly.
Welcome to Tyria, and good luck!
or you can make a guild research guild bank and transfer stuff through there
that’s odd, according to http://wiki.guildwars2.com/wiki/Mail you should unlock the mail feature at level 6 (though i cant confirm this myself as that restriction did not exist at launch when i was levelling my first character)
Aside from level 6, mails get locked for a certain time (I think 3 days?) after account creation to prevent gold selling via bots.
Guild banks are similar – you cannot take out or deposit items into a guild bank until you’ve been in said guild for ~3 days.
Stop treating GW2 as a single story. Each Season and expansion should be their own story.
