Product features
MailSlurp features for sender-health and deliverability operations
Run deliverability checks, inbox placement tests, sender monitoring, and launch-readiness workflows with MailSlurp so teams catch spam-folder placement, domain drift, risky recipients, blacklist exposure, 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 placement and spam-folder evidence
Send into controlled MailSlurp inboxes and inspect arrival, folder placement, 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, blacklist checks, spam testing, and campaign probes with sender monitoring so launch owners can catch stale recipients, broken assets, and auth drift in one workflow.
