Skype: Emailing Upgrade Notices to Long-Closed Email Addresses

Microsoft Skype sent a massive emailing out warning customers in Scandanavia that their Skype versions were soon to be phased out and urging them to upgrade. The mailing hit around 50 spamtraps. The ESP is Acxiom.

Does Skype ever check its logs and remove undeliverable email addresses? Does Acxiom do so? Or do both think that this is not necessary for email addresses associated with customer accounts? 🙁

Den nya versionen har högre prestanda och de senaste funktionerna och sÀkerhetsuppdateringarna, sÄ att du fÄr bÀsta möjliga upplevelse med Skype.
