I've just received the strangest email:
I don't understand why anyone would send an email like this. It doesn't look to be asking for credentials of any kind. Is this a scam which is designed for you to engage with the sender?
It is possibly an attempt at Bayesian Poisoning of your spam filter. Spam filters work by analysing words in the email and assigning them a spam value. One form of Bayesian Poisoning is to send an innocuous email that contains mostly "good" words and one or two "bad" words. The spam filter will see the message as not spam and over time it can be trained to assign these "bad" words a lower spam value - which will allow more spam though.

No, a phish would be trying to extract information from you in the form of an attachment or a link, usually to get credentials. This is just spam.
Judging by the contents and the fact that this mail landed in your inbox, this is not a Phishing email.
I think this mail was intended for someone else and maybe the as sender accidentally filled in the wrong email address (this has happened to me once).
