Give every campaign, lifecycle sequence, or sender its own probe mailbox identity so copies land in a controlled destination instead of scattered spot-check inboxes.

Use MailSlurp campaign probe workflows to detect broken links, missing assets, template drift, and sender-readiness issues with repeatable inbox checks instead of manual spot reviews.

Product features
Use seeded probe mailboxes, scheduled analysis, durable health state, and run history to keep campaign quality visible over time.
Give every campaign, lifecycle sequence, or sender its own probe mailbox identity so copies land in a controlled destination instead of scattered spot-check inboxes.
Keep recurring checks active and review the last known score and run status for each monitored campaign without re-creating one-shot audits.
Every probe run can score the message for broken links, missing images, HTML issues, client-compatibility warnings, and stored reputation verdict failures.
Compare the latest run against an earlier healthy baseline and use trend views to see when message quality started to slip.

Keep dedicated inboxes watching campaign and notification quality before or after launch instead of depending on one-time review.

Send failures and quality signals into webhooks, queues, or internal dashboards so fixes reach owners faster.

Combine content evidence with domain and authentication checks for a tighter release-readiness workflow.
Developer integration
Move sender posture checks and reliability events into scheduled jobs, dashboards, or alert pipelines with the same API.
