What does my email security grade mean?

Why are Google and Microsoft rejecting my emails?
In February 2024, Google and Yahoo began requiring SPF, DKIM, and DMARC for all bulk senders. Microsoft followed in May 2025. As of November 2025, Gmail hard-rejects non-compliant email \u2014 messages never reach the inbox. If your grade is below B, your emails are at risk.

What's the difference between SPF, DKIM, and DMARC?
SPF tells email servers which IPs can send on your behalf. DKIM adds a cryptographic signature proving emails weren't tampered with. DMARC ties both together and instructs receiving servers to quarantine or reject failing emails. You need all three for an A grade.
