I got an email inviting me to a study as it appears I set the settings for it. However I am skeptical to its realness as:
-  All links do not point to a SO/SE site, but instead to a cryptic link for a site called "pstmrk" and "rallyuxr".
- There is a monetary incentive given (with an asterisk going nowhere?), which seems rather uncharacteristic of SO. The subject line reads "Tell us about your experience on Stack Overflow ($60.00 for 60 minutes)"

Otherwise the e-mail appears convincing as the sender seems to be research@stackoverflow.com, but as far as I know that can be faked as well. 
Here is how it looks:

The mail was received on Sep the 6th 2024 (Friday) at 14:35:04 UTC. Past communications with SO/SE did not include any external links.

The header:

Some of the meta data I could fetch:

    SPF: Pass with domain pm-bounces.stackoverflow.com"
    DKIM: Pass with domain stackoverflow.com"
    DMARC: Pass

Should one click a link it will be blocked by tracking protection (in this case [uBlock Origin][3]):

So is the mail/links real?
