Your ESP says "delivered" — but delivered doesn't mean seen. Our test shows exactly where your email lands at each provider. Primary inbox. Spam folder. Promotions tab. Or missing entirely.
Gmail might put you in the inbox while Outlook sends you to spam. The test breaks down placement for each mailbox provider individually — so you know which providers are filtering you (and which ones aren't).
Failed SPF, DKIM, or DMARC authentication tanks placement instantly. The test flags any failures so you can fix configuration issues before they cost you opens.
A 50% inbox placement rate means half your list never sees your email. They didn't ignore you or unsubscribe. Your message just never arrived in their inbox.
As a result, open rates drop, reply rates collapse, and campaign ROI goes down. And you're left wondering why emails go to spam when the problem was placement all along.
The gap between "delivered" and "placed in inbox" is where campaigns fail. Your ESP shows 98% delivery, which means almost nothing if 40% of those delivered emails landed in spam folders.
See inbox vs. spam vs. promotions for Gmail, Outlook, Yahoo, and other major providers. The breakdown reveals patterns — spam placement across multiple providers signals reputation issues, while filtering at one provider points to content problems.
Did your SPF, DKIM, and DMARC pass? A single failure accounts for most placement problems. You can verify your current records using our SPF lookup, DKIM lookup, and DMARC lookup tools.
Content that looks fine to you might trigger filters. Your report highlights specific issues—suspicious links, formatting problems, or phrases that trigger spam filters.
