Why would you think this was spam? It clearly isn't. I had one too and they had upgraded my speed automatically as I knew they would eventually without me doing anything. I have no idea what VM staff are up to. There are free upgrades.
The mail shows no signs of spam. It does not contain an obviously dodgy phishing link. There are no suspicious images and the wording matches VM's advertising and promotion for its cable system. That would be spam. What would any spammer have to gain from sending this?
Superuser 2017/18 Use Kudos to say thanks Mark answer as "helpful" only when the problem is solved Please don't send me private messages unless I ask you to. I do not work for VM. The advice I give is based on my best understanding of VM policy and practice. You rely on it at your own risk.
