The Common DNS Mistake That Breaks Business Email
You finally launched your brand-new website—only to realize your business email has stopped working. If this sounds familiar, you’re not alone.
At BBComputing, we frequently hear from small business owners experiencing email failures after a web designer launches their new site. It’s frustrating, disruptive, and often leads to lost leads and frustrated customers. But why does this happen?
The answer lies in DNS misconfiguration—specifically, a common mistake made when switching a website to new hosting. Fortunately, fixing it is straightforward if you know what to look for.
What Went Wrong? Your Web Designer May Have Changed Nameservers
Most web designers focus on one thing—getting your new website live. However, many don’t fully understand Domain Name System (DNS) management, which controls not just your website, but also your email, security settings, and other business-critical services.
Here’s the most common mistake we see:
1. A designer builds a new website on a new hosting provider.
2. On launch day, they update the nameservers to point to the new host.
3. The website goes live successfully. 🎉
4. But all previous DNS records (including email settings) are erased because the new hosting provider isn’t configured for your email.
5. Suddenly, emails stop coming in, and team members can’t send messages. 🚨
How to Tell If This Happened to You
If your website works but your email doesn’t, you might be dealing with a DNS issue. Other symptoms include:
• You’re not receiving emails, but people can still send them without errors.
• Employees get bounce-back messages when trying to send emails.
• Clients report that emails they send to you are getting rejected or lost.
• Your business email is suddenly marked as spam.
The good news? This is fixable.
The Fix: Restoring Your DNS Records
If your email stopped working after a website update, you’ll need to:
✔️ Restore your original MX (Mail Exchange) records so emails route correctly.
✔️ Ensure your SPF, DKIM, and DMARC records are in place to protect deliverability and prevent emails from landing in spam.
✔️ Add back any missing DNS records for other services like Microsoft 365, Google Workspace, VoIP systems, and CRMs.
This can be overwhelming if you’re not familiar with DNS settings—but that’s where we come in.
