MX Toolbox provides network and email infrastructure monitoring tools, including DNS lookups, blacklist monitoring, and email deliverability testing. CodeWords integrates MX Toolbox to automate email health monitoring and troubleshooting workflows.
Connect MX Toolbox to CodeWords to automate email deliverability monitoring, DNS health checks, and blacklist detection across your infrastructure.
Monitor blacklist status. Check your email server IP addresses against multiple blacklist databases regularly, receiving immediate alerts when your domain or IP appears on any list so you can take corrective action before email deliverability suffers.
Verify DNS configuration. Validate DNS records including MX, SPF, DKIM, and DMARC settings to ensure proper email authentication and delivery, identifying configuration issues that could cause messages to be rejected or marked as spam by recipient servers.
Test email deliverability. Run automated deliverability tests to major email providers, checking whether your messages reach inboxes, land in spam folders, or get rejected, providing insights that help optimize sending infrastructure and content strategies.
Analyze SMTP configuration. Examine SMTP server settings and connections to identify issues with port configurations, TLS encryption, or authentication that might prevent successful email delivery or create security vulnerabilities in your email infrastructure.
Check domain reputation. Monitor domain and IP reputation scores across major email providers to understand how your sending infrastructure is perceived, helping you maintain good standing and maximize inbox placement rates over time.
Track email server uptime. Monitor email server availability and response times continuously, detecting outages or performance degradation quickly so technical teams can respond before users experience disrupted email communication or service complaints.
Validate SSL certificates. Check SSL certificate validity and expiration dates for mail servers, ensuring encrypted connections remain secure and preventing email delivery failures that occur when certificates expire without timely renewal.
Audit email authentication. Review SPF, DKIM, and DMARC implementation for compliance with email authentication best practices, identifying gaps that could allow spoofing, reduce deliverability, or expose your domain to reputation damage from impersonation.
Create comprehensive monitoring systems that track blacklist status, DNS health, and deliverability metrics in real-time, alerting teams to issues before they impact campaign performance or customer communications.
Build systems that detect deliverability issues through MX Toolbox checks and trigger remediation processes, such as IP warm-up adjustments, content modifications, or list cleaning activities to maintain optimal inbox placement.
Develop automated reporting for marketing agencies or IT service providers that regularly assess client email infrastructure health, identifying configuration issues and providing actionable recommendations to improve deliverability and security.
