It's always good to double check but this is legitimate.
It seems like there was an issue with the system used to send out mail so it hasn't come through from our research team and the usual formatting, and instead directly from Tom (who just so happens to work in the research team)!
For anyone else seeing this, make sure you don't just click any links that are sent to you in email before validating them! It's easy to spoof a URL to show one thing in the email but take you elsewhere when you click on it.
In this case, jagex.eu.qualtrics is the service we use for our surveys and can be trusted. If you see this in any emails you are sent, make sure you double check its taking you to the actual link and not somewhere else!
Why in the world would you send actual communications through email and not the message inbox on runescape.com that exists for this exact purpose?
I believe it is to do with the information that was provided to us via the annual survey for those who were interested in asked further questions.
Typically we'll always send an inbox message as it's definitely the preferred option to prevent this exact situation from occurring! From what I understand, we didn't have the RSN from everyone who filled the survey out, in which instances email was our only choice.
