Monitoring

MailSlurp monitoring is for the part of messaging work that starts after you have already built the workflow. Once messages are flowing, teams need to know whether sender configuration drifted, campaigns are rendering correctly, and delivery behavior still matches expectations.

What monitoring covers​

  • sender-domain posture and DNS health
  • campaign capture and review
  • delivery confidence checks across cohorts
  • sender reputation and quality guardrails

Choose the right monitoring workflow​

Domain health and sender configuration​

Use Domain Monitor when you need to keep SPF, DKIM, DMARC, MX, and related sender setup under watch over time.

Live campaign capture and review​

Use Campaign Probe when you need to capture real campaign output and inspect what recipients are actually getting.

Launch and canary validation​

Use Deliverability tests when you want a pass/fail result over a selected inbox or phone cohort during a release or send.

Message quality review​

Use Email audit and Device previews when the question is not "did it arrive" but "did it look and behave the way we expected."

How teams usually adopt monitoring​

  1. Start with one domain, one campaign type, or one release cohort.
  2. Define the checks that actually matter for your team.
  3. Use the results to tighten launch and approval processes.
  4. Expand to continuous review for production sends and sender domains.
