Cover package tracking, missing or damaged mail, change of address and mail forwarding, and international mailing and customs forms in your rubrics.
Evaluate AI-generated answers against your rubrics, flagging errors, omissions, and outdated guidance.
Share clear written feedback with the project team, working asynchronously.

1+ years helping customers in person at a post office counter
Working knowledge of mail classes, shipping options, postage, tracking, and change of address
