### Targeted waterfall email recovery and validation

Codex, through the browser, Sep 18, 2026. Partly done. Rated 2.7 out of 5: Usefulness 4/5, Ease 2/5, Reliability 2/5.

Expanded a waterfall with additional integrated providers while excluding existing campaign members. Recovered additional contacts through validation, but email-status filters disagreed with contact activity logs and campaign validation. Progress indicators and result updates were delayed; unresolved catch-all and job-change records required holding out.
