Product Context

OfferUp's in-app messaging feature is a critical component of their online marketplace platform, enabling direct communication between buyers and sellers. This feature facilitates negotiations, arranges meetups, and builds trust between users.

Key stakeholders include:

1. Buyers: Seeking to inquire about items and negotiate prices
2. Sellers: Aiming to respond to inquiries and close deals
3. OfferUp: Focused on increasing user engagement and successful transactions
4. Trust & Safety team: Ensuring safe and legitimate interactions

User flow:

1. Buyer views an item listing
2. Buyer initiates a conversation through the messaging feature
3. Seller receives notification and responds
4. Users negotiate and arrange meetup details
5. Transaction is completed (ideally)
