Placement data from more than one angle.

No single signal tells you the whole truth about deliverability, so Inbox Tracker combines several. Licensed mailbox data shows where your mail actually lands for real people, inbox or spam. Seed accounts, including ones modeled to behave like different kinds of subscribers, test placement across scenarios a single test inbox would miss. And a direct Google Postmaster connection pulls Gmail's own view of your reputation and authentication. Together they tell you what happened, why, and where, for the mail you send wherever you send it from.

Frequently asked questions.

Everything you need to know

Email deliverability measures whether your emails reach subscribers' inboxes. Inbox Tracker measures this through actual consumer behavior data, licensed mailbox placement data, and traditional seeds.
How do I know if my emails are going to spam?+

What are spam traps and why should I monitor them?+
Spam traps are email addresses used to identify spammers. Inbox Tracker provides daily break-downs of spam trap hits to help maintain good inbox placement.
How do I track email campaign performance in real-time?+
Inbox Tracker monitors campaign performance at the ISP-level in real-time, alerting you to deliverability issues before they harm your sending domain reputation.
Where does Inbox Tracker's data come from?+
It combines several sources: licensed mailbox data that shows where your mail actually lands for real recipients, seed accounts that test placement across different scenarios, and a direct Google Postmaster connection for Gmail's own reputation and authentication view. Using them together catches issues any single source would miss.
Why isn't one data source enough?+
Different mailbox providers weigh different things, and each kind of data answers a different question: real mailbox data shows the outcome, Postmaster data shows Gmail's reasoning, and seeds test specific scenarios. Relying on just one leaves blind spots and false alarms; combining them gives you a placement picture you can act on.
