I've been seeing messages like this constantly make the inbox in Gmail over the last few months (even after reporting at least 3-4 of this exact type of message).

Shouldn't this be a relatively easy catch for the spam filters? Seems like it has a few features that would make it stand out:

- Low reputation domain (tudkkuyfylukf[.]ml)

- Sender name (YETI Backpack-Cooler) the same as previously reported spam messages

- Subject looks like many spam messages (that are caught in the filter)

- No body text in the email

Are these messages doing something particularly smart to evade the filters? What could be going on here?
