Common questions
What does the Starter plan include?
The Starter plan gives you access to every diagnostic tool: DMARC checker, SPF checker, blacklist checker, AI subject line tester and more. Unlimited one-off checks. Upgrade to Pro when you need continuous real-time monitoring.
Why are my emails going to spam?
Usually: a broken DMARC/SPF/DKIM record, a blacklisted IP or domain, or spam-triggering content. Our DMARC Checker, SPF Checker, and Blacklist Checker find the exact issue in under 60 seconds..
How do I check if my domain is blacklisted?
Enter your domain or IP into the Maillead Blacklist Checker. It scans 100+ major DNS blacklists in real time and returns results with step-by-step delisting guidance for any list you're on. Results in seconds.
What does DMARC actually do?
DMARC tells receiving servers what to do when an email fails SPF or DKIM. Without it, anyone can spoof your domain for phishing. Google and Yahoo now require it for bulk senders.
What does Pro add over the Starter plan?
Starter is great for diagnosing a specific problem. Pro ($29/mo) adds continuous daily monitoring, with real-time alerts the moment your domain appears on a blacklist or DNS records change unexpectedly. You know before your customers do.
How is Maillead different from MxToolbox?
MxToolbox is built for IT admins, with a dated interface and paid plans jump to $129/month with nothing in between. Maillead is built for marketers: plain-English results, AI-powered tools, expert guides, and unbiased reviews. Monitoring starts at $29/month.
