Inbox Placement Rate Definition - What is Inbox Placement Rate?

Inbox Placement Rate (IPR) is the percentage of sent emails that were able to reach the targeted inboxes rather than the spam or junk folders of subscribers.

If you have a low inbox placement rate, it may be due to;

  • Irrelevant content,

  • Bad IP and/or domain reputation,

  • Constantly sending messages to invalid or unknown email adresses.
