How long until I see data?

Short answer

Expect your first reports within a day or so of completing setup, and a useful picture within the first week.

Why it isn't instant

DMARC monitoring depends on mailbox providers (Google, Microsoft, Yahoo and others) sending you aggregate (RUA) reports. These are batched and sent on the providers' own schedule — typically about once a day. So even with everything configured perfectly, you're waiting on the next reporting cycle for data to appear.

A few things affect timing:

• DNS propagation (direct ingest): after you publish your _dmarc record with rua=mailto:<token>@rua.blankitt.com, the change can take from a few minutes up to a few hours to propagate before providers pick it up.
• Mail volume: the more mail your domain sends and the more places it lands, the sooner and more completely reports arrive. Low-volume domains see data trickle in more slowly.
• Reporter behaviour: not every receiver reports, and they each send on their own once-a-day-ish cadence, so coverage builds up over the first several days.

What you'll see, and when

Timeframe	What to expect
First ~24 hours	First aggregate reports begin to arrive; Dashboard and Reports start to populate
First few days	More reporters check in; Offenders and source-IP breakdowns fill out
~1–2 weeks	Enough data to confidently identify and align all legitimate senders, then start the Policy Progression Wizard toward quarantine

How to check progress

• Reports page — see ingested reports as they arrive (and upload report files manually if you want to get going faster).
• Sync page — if you're using mailbox sync, confirm runs are completing and reports are being imported.
• Getting Started — the live 4-step checklist shows what's done and what's next.
• Dashboard — summary stats and trends once data is in.

I've waited and still see nothing — what now?

Check the basics first:

• Confirm your _dmarc record is published correctly using the free checker at https://blankitt.com/dmarc/check, or view the live DNS records on the domain's detail page.
• Make sure your rua= address exactly matches the inbound ingest address shown in Settings.
• If you're using Mailbox sync, check the Sync page for run history and that the mailbox is still connected.
• Remember that very low-volume domains simply generate fewer reports — give it a few more days.

DMARC reporting is authentication monitoring only — it tells you who is sending as your domain and whether they pass SPF/DKIM alignment. It has nothing to do with spam or content filtering.
