Is an electronic acceptance legally binding?

Yes. Electronic signatures meet ESIGN Act standards (15 U.S.C. §7001) and UETA in most states if intent, consent, attribution, and record retention are satisfied.

Do I need notarization for an advertising letter?

Typically no. Advertising Opportunity Letters are ordinary commercial agreements and do not require notarization unless a party expressly requests it or a specific transaction triggers notarial requirements.

Who can sign on behalf of the advertiser?

An authorized officer or employee with contracting authority should sign. Verify authority internally or by corporate resolution to avoid disputes over binding acceptance.

Can the letter be rescinded after signing?

Revocation depends on the contract terms and applicable law; cancellation provisions in the letter govern refunds and notice periods. Absent contract terms, common-law contract remedies apply.

What if the advertiser disputes ad performance?

Document measurement methods and reporting cadence in the letter. Use agreed KPIs and retain delivery logs and analytics to support or resolve disputes.

How should signed letters be stored?

Store signed copies and audit trails in a secure repository with access controls; retain records per tax, audit, and industry retention guidelines described above.

What an Advertising Opportunity Letter Is and When It’s Used

An Advertising Opportunity Letter is a written proposal from a publisher, media owner, or platform to a prospective advertiser describing available ad placements, audience metrics, creative specifications, pricing, and booking terms. It functions as an offer to advertise and a record of commercial terms that, when accepted and signed by the advertiser, creates contractual obligations between the parties. Typical uses include media kit outreach, targeted campaign proposals, sponsorship offers, and inventory reservations for print, digital, outdoor, or broadcast placements.

Why a Clear Advertising Opportunity Letter Matters

A precise Advertising Opportunity Letter reduces misunderstandings about placement, timing, and creative requirements, and provides a clear acceptance path that supports enforceability. It serves as both a sales document and a contract-ready record useful for billing, production, and compliance.

Legal / Finance Teams — Reviews payment terms, indemnities, and ensures contract language aligns with company policy.

No audit trail — relying on email threads without a signed document increases risk if the advertiser later disputes terms.
