Prompt
How do I check MX records for an email domain?
Latest observation
You can check MX records with a DNS lookup tool.
Common ways
1) dig (Linux/macOS)
dig MX example.com
For a shorter result:
dig +short MX example.com
2) nslookup (Windows/macOS/Linux)
nslookup -type=mx example.com
3) host (Linux/macOS)
host -t mx example.com
What to look for
MX records list the mail servers responsible for receiving email for that domain. The output usually includes:
- the mail server hostname
- a priority number
- lower number = higher priority
Example
dig +short MX gmail.com
Might return something like:
10 alt1.gmail-smtp-in.l.google.com.
20 alt2.gmail-smtp-in.l.google.com.
Online tools
You can also use DNS lookup websites by searching:
- “MX lookup”
- “DNS MX record checker”
If you want, I can also show you how to check MX records from Python, PowerShell, or a web browser.

Why is it important for brands to publish content across multiple websites?
Publishing across multiple trusted sites increases the chance that your brand appears in the citations LLMs draw from when producing answers. Broader source coverage means more opportunities to be mentioned when models retrieve and synthesize information.
