Company-email verification, account review, proposal responses, and collaboration status appear in the service and notification surfaces. When an important notification arrives, open the linked proposal or conversation and verify the current state and participants. Sign out on shared devices and never send Google credentials, passwords, verification links, or one-time codes to another person.

Only an advertiser account that has completed Google sign-in, company-email verification, and operational review can send a proposal. Review the creator profile and recent public content first. Explain the product, objective, channel-specific reason, deliverables, compensation or negotiation approach, schedule, and requested rights. Do not ask a creator to guarantee an unverified performance result or positive opinion.

Use verifiable identity and enough information for the other party to make a decision. A proposal should state the campaign objective, format, compensation approach, schedule, disclosure, and requested rights. Independently verify advance-payment requests, password or verification-code requests, unfamiliar files, and sudden payment-detail changes. Keep important agreements and later changes in a record visible to the participants.

Advertisers first sign in with a Google account, then submit company, brand, contact, website, and company-email information. The Google account is used for sign-in; the company email is verified separately for affiliation checks and approval updates. Sponsorship proposals remain unavailable until company-email verification and operational review are complete. Check the service screen and registered contact route for the current status.

Danchuu helps brands, advertisers, and creators review sponsorship opportunities using published information and clear terms. Advertisers sign in with Google, verify a company email, and complete company review. Creators complete account and YouTube channel review and publish an approved channel before using the relevant marketplace features. Public information starts a conversation; the parties still confirm final deliverables, compensation, schedule, disclosure, and rights directly.
