Product features
MailSlurp features for sender-health and deliverability operations
Run deliverability checks, sender monitoring, and launch-readiness workflows with MailSlurp so teams catch domain drift, risky recipients, and campaign issues before they damage trust.
Scheduled SPF, DKIM, DMARC, BIMI, and MX checks
Monitor the sender-domain records and routing signals that most often break inbox trust before customers see a delivery problem.
On-demand reruns after DNS and provider changes
Recheck sender posture immediately after a DNS edit, provider cutover, or launch change instead of waiting for the next scheduled run.
Inbox receipt checks with saved message records
Send into controlled MailSlurp inboxes and inspect arrival, headers, links, and body content when a launch decision needs a real received message to review.
Verification and campaign probes around high-risk sends
Pair address verification and campaign checks with sender monitoring so launch owners can catch stale recipients, broken assets, and auth drift in one workflow.
