Unsolicited email thanking me for a recent 'purchase'?

Today I received two emails ostensibly from HelioHost, one (from support@heliohost.org) about the updated terms of use, and another (from noreply.invitations@trustpilotmail.com) thanking me for a recent purchase from HelioHost and asking me to rate it. Interestingly, it addressed me by my first name, which it could have just grabbed from my email, but which I don't know is otherwise associated with my HelioHost account.

I don't recall making a 'purchase' from HelioHost short of a $5 donation I made in 2021 to move my website to Tommy. As a result, I just wanted to reach out to ask if this was sent in error, or elsewise why it was sent, or if it's some sort of scam or phishing attempt (in which case I figured you ought to know about it anyway!).

A copy of the email is attached. Thanks for your time, and sorry for any trouble or inconvenience.
