Poking my brain, I can see it's crackable, since the three letters in a row combos solve at least one of the letters, since we can tell it's been rearranged and those are articles mashed together. So it's likely X=A, or H=I. I could probably keep looking at it, it's definitely just letter replacement and not anything more interesting, so whoever sent it to you wants you to get the decoder ring out of your Fruity Pebbles and probably meet them underneath the Big Tree behind the neighbor's house
edit: actually, nevermind, this just seems like total gibberish in that case "HHHRS HHHRK XXRXA XXXRH MMMVK", letters just don't go that way together, but it doesn't lessen how much this situation reminds me of being eight. So no, my tired brain had a moment of deluding itself lol.
Now I'm convinced the biggest mystery here is how anyone could think "cyan sunset" was a good idea for a font color.
