Inspect the provider where placement needs attention. Test the next campaign with real seed mailboxes in the dashboard.
Test the actual campaign.
With actual seed inboxes.
Register a seed test to get mailbox addresses, then include them in your campaign send. Bird checks where that email lands, so you can test the actual sender, subject and content before a wider campaign.
A seed test measures the email you send to its mailboxes. Creating the test alone does not send it.

One campaign.
Different inboxes.
See where the test email landed at Gmail, Outlook and Yahoo. Inspect inbox and spam placement with the mailbox counts behind the result, along with authentication findings. Use the provider view to decide where to focus your next change.
Inbox Insights, explained.
What is the difference between delivery and inbox placement?
Delivery means the receiving server accepted the message. Inbox placement measures where observed mail landed, using seed accounts and a measurement panel.
Does creating a seed test send the campaign?
No. Register the test, copy or download its seed addresses and include them in your own send before the displayed deadline. Results appear after the seed mailboxes receive the email.
What does a missing placement figure mean?
It can mean the domain or provider was not measured for the period, or that figures could not be retrieved. A missing value does not mean zero percent inbox placement.
