Choose the deliverability job first: measure inbox placement, diagnose a sender problem or change a sending practice. These tasks need different evidence and should not be collapsed into one score.

Compare the deliverability workflow

Capability	Bird	Validity Engage
Placement analysis	Inspect measured placement by domain and mailbox provider.	Engage presents placement testing and provider-specific deliverability insights.
Reputation and authentication	Review the available complaint, blocklist and DMARC observations in Reputation.	Engage lists Sender Score, authentication and blocklist monitoring.
Sending evidence	Inspect your Bird delivery, bounce and deferral data alongside placement.	Map the monitoring reports to the sending records your team uses.
Scope of a move	Recreate the required monitoring process and retain historical reports.	Engage also lists live email monitoring, rendering tests and Sender Certification; evaluate those separately.

Run the same customer journey

Use the same authenticated domain, content, sending route and time window for a controlled evaluation. Record seed-pool differences and actual recipient outcomes. A seed inbox rate is a measurement of those mailboxes, not a guarantee for every subscriber.

Start the working example ↗

Make the switch deliberately

Start by recreating the measurement baseline in Bird and retaining old reports. Do not change the sending provider, IP, content and audience at once; that makes it difficult to attribute the result.

Questions before switching

Does a seed test guarantee inbox placement?

No. It reports where the tested messages landed in the measured mailboxes. Compare the provider, cohort and observation window, then inspect your actual sending and customer outcomes.

Is inbox placement the same as delivery rate?

No. Delivery means the receiving server accepted the message. Placement measures where a message landed. Keep those observations separate when investigating a sending problem.

Should I change my sender when changing monitoring?

Establish the new measurement baseline first. Changing the sender, IP, content and audience at once makes the result difficult to interpret.
