Guild Wars 2

What’s the trick to getting the “e-mail full” piece of the hints? I have ten unread mails, but the item doesn’t get checked off in my achievement.

I think the storyline/living story mails don’t count.
So only player mails and black lion parcels.

“Certain event-related mail will count against the inbox limit, although it does not count for hints. "

Every once in a while, I’ll see someone in /map chat ask for people to spam them with mail, and I assume this is why. Just find a busy map and say please.

I have 10 in-game mails in my inbox from my daughter. The hint is unimpressed.

The hint is a harsh and fickle mistress.

In seriousness, I have no idea what the trouble is, then. This is probably obvious, but have you tried sending an eleventh, so that the mailbox overflows, rather than just being full?

Hrm.

Hm, completely clean out your mailbox and tell your daughter to mail you 11 times with 1 copper in each one. And don’t retrieve the copper until it is all finished. This should cover all your bases.
