# Reliability and sender-control products

Protect sender trust, launch readiness, and alert ownership with reliability-first workflows for email teams.

MailSlurp reliability products help teams catch the failures that are easiest to miss until customers notice them: DMARC, SPF, DKIM, and BIMI drift, broken approval paths, and launch decisions made without sender-health evidence.

## Jobs to be done

### Protect sender identity and domain health

- DMARC, SPF, DKIM, and BIMI monitoring
- Domain posture reviews before launches and migrations
- Drift detection for selectors, policies, and auth ownership

Start with [DMARC, SPF, DKIM monitoring](https://www.mailslurp.com/product/dmarc-spf-dkim-monitoring/) and the [DMARC checker](https://www.mailslurp.com/tools/dmarc-checker/).

### Add reliability evidence to pre-send reviews

- Broken-link and missing-image audits
- Rendering and launch-readiness checks
- Shared approval signals for lifecycle, compliance, and platform teams

Start with [Email compatibility tester](https://www.mailslurp.com/product/email-compatibility-tester/) and [Email deliverability test](https://www.mailslurp.com/testing/email-deliverability-test/).

### Route alerts to the team that can fix the issue

- Webhook notifications for sender and DNS incidents
- Escalation paths for shared ownership and incident response
- Workflow routing for lifecycle, platform, and compliance operations

Start with [Email proxy, forwarding, and routing rules](https://www.mailslurp.com/product/email-proxy-forwarding-routing-rules/), [Email webhooks](https://www.mailslurp.com/product/email-webhooks/), and [Webhook notifications for domain monitoring](https://www.mailslurp.com/blog/webhook-notifications-domain-monitoring/).

### Investigate failures quickly

- DNS and auth diagnostics
- Header analysis and message-level evidence
- Dashboard and run-history views for drift and remediation

Start with [DNS lookup](https://www.mailslurp.com/tools/dns-lookup/), [SPF checker](https://www.mailslurp.com/tools/spf-checker/), [DKIM checker](https://www.mailslurp.com/tools/dkim-checker/), and the [Domain monitoring dashboard guide](https://www.mailslurp.com/blog/domain-monitoring-dashboard/).
