Mailflow Monitoring

Monitor Mailflow Performance, Including Hops and Latency

Know the Moment Something in Your Mail Path Slows Down or Breaks

Email delivery problems rarely announce themselves clearly. By the time users start complaining, messages have already been delayed, bounced or silently dropped. Delivery Center's Mailflow Monitoring gives you continuous round-trip visibility into your inbound and outbound mail paths, including every hop and the latency at each, so you can detect and diagnose problems before they become a ticket queue.

  • Round-trip mailflow monitoring for both outbound sending and inbound receiving
  • Detailed hop-by-hop analysis showing exactly where delays are occurring
  • Latency tracking over time to visualize trending degradation before it becomes an outage
  • Instant alerts when mailflow falls outside your defined thresholds
  • Inbound monitoring confirms your MX infrastructure is accepting mail as expected

DNS Record Management

Simplify Management of SPF, DKIM, DMARC and Other DNS Records

One Place to Manage Every Email DNS Record That Matters

Email DNS configuration is a moving target. New SaaS tools get added, third-party senders change their infrastructure, DKIM keys need rotating, and SPF records creep toward the lookup limit. Delivery Center gives you a centralized view of your email-related DNS records with expert recommendations, making it easier to stay on top of ongoing maintenance.

SPF DKIM DMARC MX BIMI MTA-STS TLS-RPT
  • View and validate all email-related DNS records in a single interface
  • SPF Flattening to resolve lookup limit issues before they break delivery
  • DKIM selector monitoring gives you alerts if a selector goes missing or changes
  • DMARC record validation with plain-language explanations of each tag's effect
  • Recommendations on when and how to make changes without risking delivery
Configuration Issue Detection

Detect SPF, DKIM, DMARC and BIMI Configuration Issues

Find Problems Before Inbox Providers Do

A misconfigured SPF record, an expired DKIM key, a DMARC policy that's blocking legitimate email, all these problems show up as delivery failures, not configuration warnings. By then the damage is done. Delivery Center continuously checks your email authentication configuration against current best practices, surfacing issues with clear context on what's broken, why it matters and how to fix it.

  • Continuous validation of SPF syntax, include chains and lookup counts
  • DKIM selector health checks to detect missing, expired or misconfigured keys
  • DMARC policy auditing with analysis of how your current policy affects email flow
  • BIMI record validation including certificate checks where required
  • Change detection alerts you when an existing record changes unexpectedly

Stop Discovering Email Problems After the Fact

Delivery Center gives IT administrators the proactive visibility that reactive tools can't provide.

Delivery Center Dashboard

Reduce Email Troubleshooting Time

Spend Less Time Diagnosing. More Time Resolving.

Email troubleshooting is slow because the relevant data is scattered: delivery logs here, DMARC reports there, blacklist checks somewhere else. Delivery Center consolidates the information you need into a single view, so when a user reports "email isn't working," you can go from report to root cause in minutes, not hours.

  • Centralized mailflow, blacklist, DMARC and configuration data in one interface
  • Expert onboarding support and account walkthroughs to get set up quickly
  • Prioritized issue list. Know what to fix first and what can wait
  • Historical data to distinguish new problems from long-standing configuration issues

A Single Pane of Glass for Everything That Affects Email Delivery

Email delivery health isn't just about one system, it's the sum of your MX records, your sending IPs, your DNS configuration, your authentication setup and the reputation of every service sending email on your behalf.

  • Track blacklist status for all sending IPs including third-party senders
