Frequently asked questions
What do SPF, DKIM and DMARC do?
Together they prove your email is legitimate — SPF authorises sending servers, DKIM signs messages, and DMARC tells receivers how to handle failures.
Why are my emails going to spam?
Missing or broken SPF, DKIM, or DMARC records are a common cause; this checker helps you find and fix them.
