A regular phish with scary tactic that you won’t receive new messages until you click on the link to upgrade. By looking at the recipients one may notice it is a mass send email. The senser address is external and sender name is vague. The salutation and signature are generic. The link given (check by hovering over it) is also external. All these warning signs point this email to be phishing.
Never be in a hurry to click the links, think and try to spot the phishing signs. Whenever in doubt, check with helpdesk.
