Activity
A chronological audit log of account events across every resource.
Activity is the cross-resource event feed — domain verifications, template changes, campaign sends, key creation, webhook deliveries, and more, in one timeline. Where the Emails page is per-message, Activity is per-account.
It's the place to reconstruct "who changed what, when" — useful for debugging an unexpected state, confirming an action took effect, or auditing access. Every member can reach it.
