Is an electronic signature legally binding?

Yes. In the United States, electronic signatures are legally enforceable under the ESIGN Act (15 U.S.C. §7001) and UETA where adopted, provided intent, consent, attribution, and reliable record retention are met.

Do I need a printed original for enforceability?

No. A correctly executed electronic signature with an audit trail typically has the same legal effect as a handwritten signature under ESIGN and UETA, unless a statutory exception applies.

What authentication level should I require?

Choose authentication based on risk: email-only is acceptable for introductory letters; require stronger verification (SMS, ID verification) for fee acceptance or contract execution to improve attribution.

Can I include pricing in the promotional letter?

You may include estimates or ranges, but label them as estimates and reserve definitive pricing for a formal proposal to avoid claims of misrepresentation or contractual ambiguity.

How long should I keep signed letters?

Retain promotional letters and related records for at least three years for tax purposes (IRC §6501(a)) and longer if they relate to warranties, disputes, or regulated data such as HIPAA-protected information.

How can I revoke or amend a sent letter?

You can send an amended letter or a notice of revocation to the recipient and keep copies; for binding changes to price or scope, obtain a signed amendment or a newly signed agreement to avoid enforceability issues.

Practical Tips for Accurate, Efficient Letters

Follow these practices to ensure clarity, professionalism, and higher conversion from outreach to signed work.

Be concise and specific

Keep the opening to two short paragraphs, use bullet points for deliverables, and avoid industry jargon. Specificity about deliverables and timelines reduces follow-up questions and speeds proposal acceptance.

Attach visuals selectively

Include 2–4 high-quality images or a one-page portfolio PDF demonstrating similar projects. Visuals should illustrate design intent and support the claims made in the letter without overwhelming the message.

Use standardized templates

Maintain a reusable template with merge fields for client name, project address, and timeline to reduce errors and speed personalization while keeping brand consistency across outreach.

Record delivery and consent

For electronic sends, preserve delivery receipts, read confirmations, and any eSignature audit trails to document client receipt and acceptance if disputes later arise.

Who Typically Signs the Promotional Letter

Lead Designer

The studio lead or principal designer signs when the letter represents the design approach and intent; signature confirms authorship of the concept and responsibility for deliverables.

Client / Owner

Client signature or written acceptance may appear on a returned copy to indicate agreement to discuss a formal proposal or to acknowledge receipt, forming a record of initial consent.
