About OutboxWatch
OutboxWatch helps people who send cold email find out why it lands in spam, and notice when their domain setup breaks.
Check your domain nowFree SPF, DKIM, DMARC, MX and blacklist check. No signup.
Run the free checkerWhat it does
- The free checker looks up a domain's public DNS records and reports on SPF, DKIM (common selectors), DMARC, MX and domain blocklists. No signup is needed.
- Paid plans re-check your domains every day, show health scores and trends in a dashboard, and flag regressions. Plans are Starter ($29/month, 3 domains), Growth ($59/month, 15 domains), Agency ($149/month, 60 domains). See pricing.
- The guides explain cold email deliverability in plain English: SPF, DKIM, DMARC, warm-up, blocklists and complaint rates.
How we work
We only publish what we can back up. The checker reads public DNS, and when a blocklist refuses to answer it says the result is unavailable rather than reporting a pass. We don't sell your data; see the privacy policy.
