> I'm guessing some sort of partnership connection, but it's never good if you believe you are receiving unsolicited emails.
I've yet to know a "partnership connection" email solicited in any way, shape or form, for what it's worth. Even when the partnership is tight (example: I recently received an email from Radiohead's Thom Yorke. I bought In Rainbows when it was released 6 years ago, and the mail got sent to the address I provided back then [my recollection is fuzzy, but it was likely necessary to get a/the download link]. The connection is strong, but I still consider it to be spam.)
