What does Inbox Placement do?

MxToolbox Inbox Placement provides you with a simple, detailed report of where your email goes when you send email to Inbox Providers like Google, Yahoo! and Microsoft Outlook.com. Our report works with any email sending system, like HubSpot, Mailchimp, Marketo, Salesforce or 100+ more. We tell you if the email made it to the Inbox, got dumped into Junk/Spam or failed to make it to the mailbox entirely. With MxToolbox you know if campaigns, transactional or systems emails will be at risk, if your emailing reputation is problematic or if it’s the quality of your message!

Everything You Need to Avoid the Spam Folder

Inbox Placement Status

Know if your campaign will hit the Inbox or get dumped into Spam/Junk folders before you press send. We test your email acceptance across all major inbox providers so you can protect your sender reputation.

Content Quality

Passing SPF, DKIM, and DMARC isn't enough if your content triggers spam filters. Get detailed insights into spam-like patterns, image counts, link issues, and one-click unsubscribe compliance that could block your delivery.

Email Rendering

Preview exactly how your campaign looks across different email clients. MxToolbox visually renders your email and highlights formatting issues that break suggested best practices.

Adaptive Blacklist Detection

Automatically detect active blacklist reputation issues tied to your domain and sending IP addresses. Identify and resolve blocklisting threats before they impact your campaign's ability to reach the Inbox.

DMARC Compliance

Test every message for strict DMARC compliance and BIMI logo readiness. We analyze your underlying SPF Alignment, SPF Authentication, and DKIM Alignment to recommend exact changes for compliance.

Google, Microsoft & Yahoo Bulk Sender Rules

Maintain compliance with constantly changing Bulk Sender rules. We run specific tests against Google, Microsoft, and Yahoo! thresholds, including spam rates under 0.3%, DMARC Reject policies, and one-click unsubscribe functionality.

SPF, DKIM & DMARC Configuration

Prevent total email rejection by ensuring valid SPF and DKIM configurations. We perform a deep technical analysis of your email headers and DNS records to verify your authentication setup is completely compliant.

Inbox Provider Spam Rules and Proprietary Blocklists

Bypass hidden filters. Even DMARC-compliant emails can fail due to proprietary blocklists, Content issues, or poor Domain Reputation. We proactively test against provider-specific spam rules to uncover these hidden delivery blockers.

How does the Inbox Placement test work?

MxToolbox gives you two seamless ways to run a complete email spam test and monitor your delivery:

  1. Pre-Send Campaign Testing: Before launching a new newsletter, nurturing sequence, or billing notification, send a test email to our proprietary seed list. We'll show you exactly how it performs across major providers before you send it to your customers.
  2. Continuous List Monitoring: Add our test inboxes directly to your active mailing lists. Every time you send a campaign, you'll receive continuous, automated insight into your inbox placement and sender reputation.

Our straightforward integration ensures you get actionable infrastructure data without slowing down your marketing team.
