What Is an Inbox Placement Test?

What this is

An inbox placement test shows where your emails land across different email providers, such as inbox, promotions, or spam.


Why it matters

Even if your emails are successfully delivered, they may not be seen. Placement directly impacts open rates and overall campaign performance.


How it works

  • Your email is sent to a controlled list of test inboxes (seed list)

  • These inboxes are hosted across major providers like Google and Microsoft

  • The system tracks where your email lands


What you’ll see

  • Inbox placement rate

  • Spam placement rate

  • Promotions or tab placement

  • Provider-specific results


Expert insight

Delivery does not equal inbox placement. You can have 100% delivery and still land in spam.
