It’s a template email sent to everyone that is genuinely trying to help. Even as a graduate you’ll probably have access to your university careers service. Most universities will give you access to their services for somewhere between 3 years to indefinitely after graduation
You are right, I totally understand that, but I'm sure they also realise that so many applicants will have had their applications checked and double-checked. It almost makes the rejection harder by simplifying it to a list of qualities followed by "your university careers service will be able to tell you where to improve these". Some applicants may have done so already, and some rejections may just be down to the volume of applicants rather than the application being weak in areas where a career service can help. I know from recruiting experience that sometimes it can be very minor and company-specific details that get an application rejected, such as a few words that makes you think that the candidate does not fully understand the role. For me anyway, accompanied with the lack of greeting in the email, it made it feel even more impersonal than a standard rejection email.
But I'm sure I'm just being a negative Nelly and it probably did help some people! I hope that it did at least and it's just me that feels this way...
