Three steps, total time 3-5 minutes for the first domain, 60 seconds per additional one.
1. Add the domain in the dashboard
Sign in, go to Domains, click "Add domain", paste the apex (yourdomain.com - no www).
2. Verify ownership
We give you a TXT record. Add it via your DNS provider (Cloudflare, GoDaddy, Route53, etc.). Verification typically resolves within 60 seconds; we re-check every 30 seconds for the first 10 minutes.
3. Point your DMARC report URI at us
Update your DMARC record's rua= and ruf= to include your unique ShieldMarc ingest address. From the next morning's report cycle (most receivers send daily) we'll start showing you authenticated and unauthenticated senders.
What happens next
We auto-classify each sender, score the domain, and email you when something changes (new sender, score change, lookalike domain registered, etc.).
