This campaign branch is ready for launch review

Pair template QA with sender readiness

Use repeatable checks for links, previews, content, and sender posture so lifecycle, engineering, brand, and compliance owners can make the same launch decision.

Campaign QA workflows MailSlurp supports

Broken link and asset checks

Find broken CTAs, missing images, mailto link mistakes, tracking problems, and content issues before campaign approvals are complete.

Sender readiness signals

Pair content checks with DMARC, SPF, DKIM, MX, unsubscribe headers, spam checks, and inbox placement evidence for a stronger launch decision.

Open deliverability monitoring

Release gates for important sends

Define which rendering, link, image, authentication, and unsubscribe issues block launch and keep pass/fail results visible for recurring campaign and lifecycle work.
