Topics we route first
City and content partnerships
Local organizations, schools, media, communities, and service providers should describe the city, contribution, and intended collaboration.
Business, advertising, and promotion
Stores, recruiters, housing teams, and services should include entity details, scope, pricing or fees, and target city.
Product, account, and privacy
Include the platform, operating-system version, reproduction steps, and request type. Sensitive documents are not needed in the first email.
Response and review boundaries
Routed by subject
Messages are categorized as partnership, product, safety, privacy, or commercial matters. Complex requests may require additional information.
Submission is not approval
An email does not mean a partnership, advertisement, listing, role, or business verification has been approved, and no fixed response time is guaranteed.
Do not use email for emergencies
For immediate danger, active fraud, or suspected crime, contact local police, emergency services, your payment provider, or another qualified channel first.
