@Irgendjemand What emails are you referring to? Are they asking for any personal information though you've never contacted us? If yes, that could be a scam, as we would never ask for private information unless you have initiated a request that needs anything as such, also, do not pay for any service as the HP community is a free public forum.
Let me know if you need anything else, and include the product information (not the serial number) and a brief note about the issue, so I can help you out.
P.S: Welcome to HP Community 😉
I hope that answers your query,
