Add DNS Records to MuuMuu Domain

To send emails using your private domain name, you will first need to add your domain and create a subdomain within your Benchmark account. After the subdomain has been added, Benchmark will generate the DNS record that you'll add to your MuuMuu Domain (ムームードメイン) account using MuuMuu DNS custom settings.

This guide provides step-by-step instructions for adding the Benchmark DNS record to MuuMuu Domain.


Topics Covered in This Article


Before Getting Started

  • Benchmark does not have access to your MuuMuu Domain account.
  • Your DNS record is unique to the domain and subdomain you added to Benchmark.
  • Once your record is created, find it under Email Settings > Domain.
  • Propagation can take up to 48 hours, though MuuMuu Domain typically applies changes within about an hour.
  • Your domain's nameservers must already be set to MuuMuu DNS before you can add custom DNS records.

How to Add Your DNS Record to MuuMuu Domain


\The instructions included in this article were developed using resources from MuuMuu Domain.


  1. Log in to your MuuMuu Domain Control Panel.
  2. From the left menu, go to Domain Operations > MuuMuu DNS (ドメイン操作 > ムームーDNS).
  3. Click Use or Change (利用する / 変更) next to the domain you're updating.
  4. Click Custom Settings (カスタム設定) near the bottom of the page.
  5. Click Proceed to Setting 2 (設定2へ進む) — Setting 2 is for records used with services outside of GMO Pepabo, which applies to Benchmark.
  6. Click Add Setting (設定を追加する), then enter the details for your new NS record using the values provided in Benchmark:
    • Subdomain (サブドメイン): paste the hostname provided in Benchmark. NS records require a subdomain to be entered.
    • Type (種別): select NS from the dropdown.
    • Content (内容): paste the nameserver value provided in Benchmark.
  1. Click Add Setting (設定を追加), then click OK on the confirmation pop-up.
  2. Click OK again on the completion pop-up to finish.

After you have finished adding the record, you may return to your Benchmark account to complete the process. If you have navigated away from the records screen, you can still verify your work by checking your domain on the Domain page. From there, click the Retry Verification button next to the domain you are validating. This will initiate a web check to confirm whether the record was added successfully. Please note that DNS record propagation — once the record is valid on the web — can take anywhere from 24 to 48 hours.


If the record is not added, your domain's verification will remain pending.

Frequently Asked Questions


Will adding this record affect my existing website or email?

No. This record only applies to the subdomain you added in Benchmark — it doesn't change or remove any existing records on your root domain.


How long does it take for my record to be verified?

Most records are verified within a few hours, but DNS changes can take up to 48 hours to fully propagate. If your domain still shows as unverified after 48 hours, double-check that the record matches exactly what's listed on your Domain page in Benchmark.


What if my domain's nameservers aren't set to MuuMuu DNS yet?

You'll need to switch your domain's nameservers to MuuMuu DNS before you can add custom records. From the Control Panel, go to Domain Operations, and set up MuuMuu DNS for your domain first — then return to the Custom Settings steps above.


Can I add records for more than one subdomain?

Yes. Each subdomain you verify in Benchmark gets its own unique record. Add each subdomain in Benchmark first, then repeat the steps above for each one.
