Email Deliverability

Inbox Placement Testing

Test where your email actually lands — inbox, spam, or missing — before you send to your real list.

What is Inbox Placement Testing?

Inbox placement testing measures where your email delivers across a network of real email accounts ("seeds") at major providers. Unlike delivery confirmation (which only says a message was accepted by the server), placement testing reveals whether it reached the inbox, spam folder, or wasn't delivered at all — replicating exactly what your subscribers experience.

How It Works

You send your email to seed addresses. Monitoring software checks each mailbox and records the placement result: inbox, spam, or absent. Results are typically available within minutes. EmailExacto's seed network includes accounts at Gmail, Outlook (Microsoft 365), and Yahoo/AOL, with results broken down per provider.

Why It Matters

Delivery rate (the number your ESP reports) only tells you messages were accepted by receiving servers — it doesn't reveal spam folder delivery. A 99% delivery rate with 80% spam placement means 80% of your subscribers aren't seeing your email. Inbox placement testing reveals this gap and helps catch emerging deliverability problems before they affect your entire list.

What to Get Right

Run placement tests with each major campaign or template change.

Test with your actual sending infrastructure — same IP, domain, and headers.

Investigate any result below 90% inbox rate at a specific provider immediately.

Compare placement before and after authentication changes to measure impact.

Include seed addresses in regular list sends for more natural results.

Track placement trends over time — a gradual decline often precedes a major deliverability event.
