When configuring Google Workspace email or troubleshooting delivery issues, verifying that your MX records are correctly set up in DNS is essential. Google provides an official and free diagnostic utility — the Admin Toolbox Dig Tool — that helps administrators check DNS records directly from the web without needing command-line tools.
This guide explains how to use Google’s Dig tool to verify MX, A, CNAME, TXT, and SPF records for your domain.
Step 1: Open the Tool
Go to the official Google diagnostic tool:
? https://toolbox.googleapps.com/apps/dig/#A/
Step 2: Enter Your Domain Name
In the Name field, type your domain name without “www.”
Example:
your-company.com
Avoid prefixes like https:// or www. — just the root domain.
Step 3: Choose the Record Type to Check
From the dropdown next to the URL bar, you can select the record type you want to look up:
A – To check your domain’s IP address.
MX – To verify your mail exchange records (used for Google Workspace email).
TXT – To view SPF, DKIM, or verification records.
CNAME – To check alias records.
NS – To see name server records.
Step 4: Click “Dig”
Once you’ve entered your domain and selected a record type, click the Dig button or press Enter.
The tool will instantly display results fetched from DNS servers worldwide.
Step 5: Verify MX Records for Google Workspace
If you are using Google Workspace, your MX records should look like this:
| Priority | Mail Server |
|---|---|
| 1 | ASPMX.L.GOOGLE.COM. |
| 5 | ALT1.ASPMX.L.GOOGLE.COM. |
| 5 | ALT2.ASPMX.L.GOOGLE.COM. |
| 10 | ALT3.ASPMX.L.GOOGLE.COM. |
| 10 | ALT4.ASPMX.L.GOOGLE.COM. |
If your domain’s MX records match the above list, your configuration is correct. If not, update your DNS settings at your domain host (like Hostinger, GoDaddy, or Cloudflare).
Step 6: Check Other Records (Optional)
You can use the tool to verify:
TXT Records: Confirm SPF, DKIM, or Google verification codes.
A Record: Ensure your website IP address is resolving correctly.
CNAME Record: Verify aliases for services like mail or www.
NS Record: Confirm your domain’s authoritative nameservers.
Step 7: Troubleshooting Tips
If records don’t match, update them in your DNS host and wait for propagation (usually 1–24 hours).
Use the “Cache check” option to see if changes have propagated across servers.
Re-run the test to confirm changes are live.
Always copy MX record values exactly as provided (with a trailing dot if required).
Avoid duplicate or conflicting MX records.
Use the tool after any DNS update to ensure propagation.
Bookmark the tool for quick access during troubleshooting.
The Google Admin Toolbox Dig Tool is a quick and powerful web-based DNS checker. It helps admins confirm that their domain’s MX, TXT, and CNAME records are configured correctly for Google Workspace, ensuring smooth email delivery and secure domain operation.
