What does the DMARC v= tag do?

/* No-JS fallback: the trigger is useless without JS, so hide it and pin the menu open inline below the topbar. Crawlers don't read this style but it ensures human visitors with JS off still reach every tool. */ .topbar-tools-btn { display: none; } .topbar-mega { position: static !important; transform: none !important; opacity: 1 !important; pointer-events: auto !important; box-shadow: none !important; border-top: 1px solid var(--color-border) !important; border-radius: 0 !important; max-height: none !important; } .topbar-mega-search { display: none !important; }

DMARC `v=` Tag — Version (v)

The DMARC v tag identifies the record as DMARC1. It must be the first tag in every DMARC record — without it, the record is ignored by receivers.

✅ Valid Values

            DMARC1        

💬 What This Tag Does

The "v" tag is a required header that tells receiving mail servers this is a DMARC record. It must always be the very first tag and its value must always be "DMARC1". Records that don't start with v=DMARC1 are silently ignored by receivers.
