I tried using Claude Co-Work to review and update emails and received this message, which is probably a bug in the Claude connector:

Separately — I hit a real problem with the Decile Hub write tool available to me: attempting to update a person's email by ID silently created a brand-new duplicate contact instead of updating the original, for all 19 people I tried first. I caught it immediately and deleted all 19 duplicates, and verified the original records are untouched (still linked to the pipeline, still showing no email) — no lasting damage, but it means I can't safely write directly into Decile Hub from here until that's fixed on the tool side.
