Having checked your inactive account, I’d be very inclined to believe that the email in question will likely have been genuine.
Now obviously I cannot guarantee this without seeing the email header information, but your inactive account certainly does fit all the ‘criteria’ we have listed here for those accounts likely to be selected for this promotion, while your previous use of such an offer does rule you out from participating again (although the offer you took up was long enough ago that it regrettably doesn’t seem to have impaired you being sent a new invitation).
Sadly this means that, in short, yes you were being offered the gametime (hence the mail), but no it unfortunately won’t be possible to claim it (having already done so previously).
I do, however, understand your confusion that such a mail be sent again if the account in question was inherently ineligible, and I shall pass this on in case the selection categories should perhaps be improved. Apologies for any worry or frustration caused in the meantime, nonetheless. :)
Incidentally, hello there also Gontier,
I was curious when I read that you’d been assured that this particular mail was fake, so I went in search of a further potential account or accounts to which it could have been referring – it seems you may potentially have two such inactive accounts, and that both of these accounts have previously made use of a 7 day promotional offer in the past, so this actual makes it far more likely that you may have received a legitimate mail (although, of course, you will have been likewise unable to claim the offer).
I do apologise if the information given to you in-game was to the contrary, although thankfully there’s been no loss on this occasion, but I’ll hopefully try and make sure that information regarding this particular promotion is disseminated as thoroughly as possible in case some of our staff may have previously missed it. :)
