Emails Not Arriving? The #1 Reason is a Broken MX Record
You just set up your new professional business email. You send a test message to your personal Gmail—it works! You reply from Gmail—and... nothing happens.
The email never arrives. No error message, no bounce back, just silence.
If you can send but cannot receive, 99% of the time, the culprit is your MX Record.
Here is how to troubleshoot the issue using the
What is an MX Record? (The "Mailroom" Analogy)
MX stands for Mail Exchange.
Think of your domain like a large office building.
- The A Record (IP Address) tells people where the building is located.
- The MX Record tells the postman exactly which door is the "Mailroom."
If you don't have an MX record, or if it points to the wrong door (server), the internet doesn't know where to deliver your incoming messages. They just get dropped.
The 3 Most Common MX Mistakes
1. Pointing to an IP Address (The Big No-No)
Unlike other DNS records, an MX record cannot point to a number (like 192.168.1.1). It must point to a domain name (like mail.google.com or https://www.google.com/search?q=mx1.hostinger.com).
2. Wrong "Priority" Numbers
You might see numbers like 10, 20, or 50 next to your MX records. These are priorities.
- Priority 10: "Try this server first."
- Priority 20: "If the first one is broken, try this one."
If you have multiple records with the wrong priority, your emails might be going to a backup server that doesn't check them often.
3. The "Double Hosting" Conflict
Did you switch from GoDaddy to Namecheap, or from Zoho to Gmail? Often, the old MX records get left behind.
Rule: You should only have MX records for ONE email provider. If you have records for both Google and Outlook mixed together, your email will break.
How to Test Your MX Records Instantly
Before you call customer support, run a quick check yourself.
- Go to the
https://findinfo.io/tool/dns-lookup FindInfo DNS Lookup. - Enter your domain name (e.g.,
https://www.google.com/search?q=your-company.com). - Scroll down to the MX Records card.
What to look for:
- Is the list empty? → You need to add records immediately.
- Do you see "Old" providers? → Delete them from your DNS.
- Do the records match your email host? → If you use Gmail, you should see
https://www.google.com/search?q=aspmx.l.google.com.
Conclusion
Email is the lifeline of your business. Don't let a simple typo in your DNS settings cost you a client. Regular health checks ensure you never miss an important message.
