Despite the name, this wizard is not limited to DMARC. Step two lets you configure SPF, DKIM, or BIMI as well.

​
Where to find it

Select DNS Tools in the left navigation. DMARC Configurator is the first tab.

​
The four steps

A progress bar tracks you through Enter Domain → Select Change → Configure → Instructions. Back returns to the previous step without losing what you have entered.

​
Step 1 — Enter Domain

Type the domain you want to configure and select Continue.

​
Step 2 — Select Change

The wizard reads your live DNS and shows what it found before you change anything:
  • The detected DNS provider, shown beside the domain name — for example Amazon Route 53.
  • Nameservers, so you can confirm you are about to edit the right zone.
  • Where to edit DNS — the exact path inside that provider’s console, for example AWS Console → Route 53 → Hosted Zones.
  • DNS Records, an expandable list of every record on the domain, with a count.
Then choose one of four things to configure:

​
Step 3 — Configure

Every option uses the same three-column layout: Element, Current Setup, and New Configuration. Your existing values sit beside the fields you are editing, so you can always see what you are changing from. Reset to Original discards your edits and restores the current live values. Select Generate Record when you are done. On DKIM and BIMI the button stays inactive until the required fields are filled.
DMARCbis, published in May 2026, removes both pct and ri from the specification. Both fields still work with receivers today, but neither is a long-term way to control rollout.

​
Step 4 — Instructions

The final step compares what you built against what is already published, then tells you how to apply it. Current DNS Record shows the record as it stands today, named by type and host — for example TXT record at _dmarc.yourdomain.com. New DNS Record gives you the record to publish, split into the two fields your DNS provider will ask for: Copy puts the value on your clipboard. Changes Applied lists every tag you altered, with the old value struck through beside the new one — for example Subdomain (sp): inherit → quarantine, or Report Interval (ri): not set → 43200s. Read this before publishing: it is the clearest confirmation that you are changing what you intended and nothing else. How to Apply This Change then walks through publishing:
1

Log in to your DNS provider

Includes a direct link to your provider’s console, using the provider detected in step two.
2

Navigate to DNS management

Named “DNS”, “DNS Settings”, “Zone Editor”, or “DNS Records” depending on the provider.
3

Create or update the record

Replace the entire record with the new value rather than appending to it. The generated record already preserves your existing settings alongside the changes, so a partial edit risks losing tags. The Type and Name are restated here.
4

Save and wait for propagation

DNS changes can take up to 24 to 48 hours to propagate worldwide.
If your new configuration turns out to be identical to the live one, you get a No Changes Detected panel instead and there is nothing to publish. That is the expected result when you open the wizard to review a domain rather than change it. Back returns to Configure so you can revise your settings. Start Over restarts from Enter Domain.
If your DNS runs on a supported provider, you may be able to skip manual publishing. See One-click DNS setup.
