> According to Validity’s analysis of 22 million sending domains, 84% have no DMARC record at all

One of those is mine (I have SPF records but no DKIM or DMARC). I don't seem to have any issues. I'm not a "bulk sender" though, and my domain has existed since 2002.

Meanwhile a whole lot of the spam I'm seeing comes either through gmail/outlook.com, or from domains with valid DKIM setups (either because the domain got owned, or because it was just 'correctly' set up... for spamming)
