Inbox Placement: How to Measure Where Your Email Lands
Delivery rate is not inbox placement. Here is how to actually find out whether your email reaches the inbox or the spam folder.
A 99% "delivered" rate sounds great — until you learn most of it landed in spam. Inbox placement is the metric that matters: of accepted mail, how much reached the actual inbox?
Delivered ≠ inbox
"Delivered" only means the receiving server accepted the message. It says nothing about whether it went to the inbox, Promotions, or spam. Providers do not report that directly.
How to measure it
- Seed testing — send to a panel of real inboxes across providers and check placement.
- Postmaster tools — Google and others expose reputation and spam rates.
- Engagement by provider — a sudden drop at one provider signals a placement issue there.
