Blocklist Monitoring
WatchCron checks your IP addresses and domains against public DNS blocklists (DNSBLs). If your server gets listed, email deliverability drops and your reputation suffers.
How it works
- Enter an IP address or domain name
- WatchCron queries major DNS blocklists periodically
- If your IP/domain appears on any list, you get alerted immediately
- Results show as Clean or Listed with the specific blocklist name
Getting blocklisted often happens due to compromised accounts sending spam, misconfigured mail servers, or shared hosting neighbors. Early detection lets you request delisting before it impacts your business.
