How do you know when a provider update actually affects you?

Knowing when a provider update actually affects you requires correlating timing with observed changes in your metrics. If your deliverability shifts align with announced or suspected update timing, and similar patterns appear across multiple campaigns and segments, the update likely affects your program.

Isolated changes in single campaigns may reflect content or list issues rather than provider updates. Widespread changes across your sending, especially matching patterns reported by others in the industry, suggest provider level changes.

Test systematically to confirm. Send controlled test messages with consistent characteristics. If results differ from baseline established before the suspected update, and the change persists across multiple tests, you have evidence the update affects your sending.
