Include seed addresses in your send

Illustrative panel estimates. Inbox placement is measured separately from your delivery events.

From a placement drop to a focused investigation.

See the measured signals, then choose the next check.

Choose your sending domain

Track verified domains in your workspace and switch between them. The report identifies the domain, measurement count and freshness of the panel data.

Compare mailbox providers

Review estimated inbox and spam rates alongside your own delivery, deferral and engagement figures. Find a provider whose placement or delivery behavior has changed.

Understand Gmail tabs

See how measured Gmail placement splits across Primary, Promotions and other tabs when the panel has data for your domain.

Test a campaign with seeds

Choose an available seed pool, engagement profile and regions. Copy or download its addresses and include them in the campaign you want to measure.

Inspect authentication on a test

A completed seed test reports SPF, DKIM and DMARC results on that send. Compare engaged and dormant mailbox cohorts when both were selected.

Connect placement and engagement

Follow the funnel from sent and delivered to estimated inboxed, opened and clicked. Bird-measured counts and panel estimates are labeled separately.

What does the placement estimate mean?

Placement comes from seed accounts and a measurement panel. Your own sending supplies delivery, open, click and deferral figures. The inboxed funnel stage applies the measured placement rate to delivered volume; it is an estimate. A missing measurement stays empty instead of appearing as zero.

Run a seed test before the next important send.

Register a test, include its seed addresses in your campaign and review the results after the mail arrives. Registration uses a test from your current allowance, even if you never send. Your workspace shows the available pools, regions, allowance and send-by date.

Start with placement and seed tests.

Open the placement report, select your verified domain and investigate its provider breakdown. Use a seed test to examine a specific campaign, with Email analytics alongside it for your sending results.

Questions about Inbox Insights

Is this called Inbox Tracker or Inbox Insights?
Inbox Insights is the current Bird dashboard product. Older Inbox Tracker product links lead here. For an existing eDataSource or legacy Tracker account, use that account’s documentation and support path; its features and access can differ.
How is inbox placement different from delivery rate?
Delivery rate records a receiving server accepting a message. Inbox Insights estimates inbox and spam placement from seeds and a measurement panel, alongside your Bird-measured delivery and engagement.
What do I need to get started?
Use a workspace with access to Inbox Insights and a verified sending domain. Turn tracking on for the domain. Some domains or providers have no panel measurements yet; seed tests require an available pool and allowance.
Does creating a seed test send my campaign?
No. Registration gives you seed addresses. Include them in your campaign before the send-by date. Results appear when those mailboxes receive the mail, and registration consumes the allowance even when no campaign is sent.
What can I check on a completed seed test?
Review where that campaign landed at measured providers, its SPF, DKIM and DMARC results, and the engaged-versus-dormant split when the test used both cohorts.
Can I use Inbox Insights through a public API?
Inbox Insights is a dashboard experience. Its internal endpoints are not a public API offering. Use the Email stats API for your own delivery and engagement reporting.
