How to get through any SPAM filter Gmail or Outlook - pose as Insurance Broker

Recently I relieved the following email from Cosmos Insurance Brokers LLC that was not caught by Gmail or Outlook SPAM filters. It because this is a click link generator SPAM, so there nothing malicious about the code there just trying to get you to download and open Documents.html to drive traffic to http://michellej.com.br and it mentions Insurance co.  Clearly it did not scan the link.

The text of email message for search engines;

This in part to do with the payload documents.html really is just a link generator pointing to this site

Looks like the rise of this sort of SPAM is coming and very hard to detect.
