What it checks
Did it prove it's you
SPF, DKIM and DMARC as the receiving server saw them, and whether they line up with your From address.
What spam filters think
The rules your message trips, the score each one costs and Gmail, Yahoo and Microsoft's sender rules.
The sending server
Its reverse DNS, its place on the main blocklists and every link in the message.
