I got a bunch of these this week.  I don't know what happens if you click the links, but they look like malware delivery vehicles.  They included a variety of graphics that look like typical credit score spam, but the sender addresses are obviously faked and the links look like they point to hacked WordPress sites like nbouhout.astblogs.org//wp-content/themes/trulyminimal/includes/framework/plugins/score_for_free.html.
