FAQ
Common questions about Inbox Placement
Everything you need to know about our inbox placement testing, blacklist monitoring, and deliverability tools.
An Inbox Placement Test (IPT) checks if your emails land in the primary inbox, spam folder, or promotions tab across different email providers like Gmail, Outlook, and Yahoo. It analyzes your email content, sender authentication (SPF, DKIM, DMARC), and checks your domain against blacklists to identify issues affecting deliverability before you send to your actual list.
We send test emails to a network of real inboxes across 50+ email providers. Once received, we check which folder each email landed in (Primary, Promotions, Social, or Spam). You'll see a detailed report showing placement rates for each provider, along with specific recommendations for improving your score.
Yes! We monitor your IPs and domains against 400+ blacklists automatically every 15 minutes. If any of your addresses get listed, you'll receive instant alerts via email, Slack, or webhook so you can take action immediately before it impacts your campaigns.
Inbox Placement testing starts at $29/month, which includes unlimited tests, blacklist monitoring, SpamAssassin analysis, and all our core features. That's $18/month less than Instantly ($47/mo) for more features.
Absolutely. You can schedule recurring tests that run automatically on your preferred schedule (daily, weekly, etc.). You can even set up automated rules—like pausing campaigns if inbox placement falls below a certain threshold—to protect your sender reputation proactively.
You'll get comprehensive reports including: inbox vs spam placement by provider, SpamAssassin score with identified issues, SPF/DKIM/DMARC authentication status, blacklist monitoring results, content analysis with spam trigger warnings, and AI-powered recommendations to fix any problems found.
Most inbox placement tests complete in under 2 minutes. You'll see results appear in real-time as they come in from different providers, with a full comprehensive report ready within minutes of starting the test.
Yes, and we highly recommend it! Running an inbox placement test before any major campaign is a best practice. It helps you identify and fix deliverability issues before they affect your actual sender reputation with real prospects.
