Business email bouncing
or landing in spam.
Three DNS records control your email: MX (routing), SPF (sender permission), and DKIM (signature). If any one is missing or wrong, email breaks.
Check your DNS records first
Go to mxtoolbox.com and run a lookup on your domain. It'll show you missing or broken MX, SPF, and DKIM records in under 10 seconds — and tell you exactly what's wrong.
Common causes & fixes
MX records tell the internet where to deliver email for your domain. If they're gone, no email arrives. Add them back via your DNS provider.
Without SPF, your outbound emails look like spam. Add a TXT record: v=spf1 include:youremailprovider.com ~all
DKIM adds a cryptographic signature to outbound mail. Find the DKIM key in your email provider's dashboard and add it as a TXT record.
If you recently migrated hosts or registrars, DNS records may have been wiped. Re-add MX/SPF/DKIM from your email provider's setup guide.
Verify your DNS records from terminal:
# Check MX records from terminal: nslookup -type=MX yourdomain.com # Check SPF record: nslookup -type=TXT yourdomain.com
