Inbox Placement
Inbox placement is the percentage of sent emails that successfully arrive in the recipient’s primary inbox, as opposed to being routed to the spam folder, promotions tab, or blocked entirely. It is the most accurate measure of email deliverability success.
Why Inbox Placement Matters
“Delivery rate” and “inbox placement rate” are not the same thing. An email is considered “delivered” if it doesn’t bounce — but it may still land in spam. A 98% delivery rate can mask a 40% inbox placement rate.
Inbox placement is what actually drives results:
- Emails in spam are effectively invisible to recipients
- Promotions tab placement reduces open rates significantly
- Only primary inbox placement reliably generates engagement
What Affects Inbox Placement
Mailbox providers decide where to place your email based on:
- Sender reputation — your historical sending track record
- Engagement signals — how recipients interact with your emails
- Email authentication — whether SPF, DKIM, and DMARC are properly configured
- Content quality — relevance, formatting, and spam trigger avoidance
- List hygiene — bounce rates, complaint rates, and inactive recipients
