Frequently asked questions
What are SPF, DKIM and DMARC?
SPF lists servers allowed to send your email, DKIM signs messages, and DMARC tells receivers what to do when checks fail.
Why does DKIM show "not found"?
DKIM lives under a selector name your provider chooses. We try common selectors; if yours is custom, it may not be detected.
