How do you test placement before major campaigns?

Pre-campaign placement testing follows a structured process:

Prepare exact campaign content: Test the actual message you will send, not a generic test.

Send to comprehensive seeds: Cover all providers relevant to your audience.

Check authentication: Verify SPF, DKIM, DMARC pass on test sends.

Review results by provider: Identify any provider-specific issues.

Check postmaster tools: Confirm reputation is healthy before sending at volume.

Allow time for adjustments: Test early enough to fix problems before the campaign deadline.

Run reconnaissance before committing your full fleet.
