Letter Format
Use a Letter Format template to make your document workflow more streamlined.
What Letter Format means
Letter Format is a structured business-letter layout that organizes the sender’s details, date, recipient, subject, message, and signature. It is not a single federally issued form, so its legal effect depends on the transaction and applicable state or federal law. In signNow, upload the Letter Format file, review or add fillable fields, assign signers, and send it electronically. The completed letter and audit trail can then be stored together. ESIGN and UETA generally recognize qualifying electronic signatures, subject to statutory exceptions and consent requirements.
Who uses Letter Format
Business operations
Businesses use Letter Format for correspondence that requires a clear sender, recipient, date, subject, body, and signature. Teams can prepare contracts, NDAs, HR communications, invoices, or consent documents when the underlying transaction permits electronic records.
Regulated teams
Legal, healthcare, financial, and construction teams can route signed letters through signNow, but each organization must apply its own privacy, retention, consent, and state-law requirements to the document’s subject.

Letter Format troubleshooting and answers
Resolve Letter Format questions by checking the document fields, signer identity, applicable U.S. law, and signNow plan capabilities.
Upload the Letter Format file to signNow, then use its fillable-field tools to place text, date, initials, and signature fields before sending.
The Business plan includes legally binding eSignatures, templates, audit trails, and mobile apps at $8/user/month when billed annually. Business Premium adds bulk send.
A typed or drawn signature can satisfy ESIGN and UETA when intent, consent, attribution, and record retention are established. Consumer transactions may also require the disclosure in 15 U.S.C. §7001(c).
Use SMS authentication or another available signer-verification method when identity risk matters. signNow records the signing event and audit trail, while your organization remains responsible for identity and access policies.
Export the completed Letter Format and its audit trail from signNow, then retain both under the applicable business or industry policy. HIPAA-covered records require six years under 45 CFR §164.530(j).
If a Letter Format document includes a will, codicil, court filing, family-law decree, or another ESIGN exception, do not rely on online signing; follow the applicable state or court procedure.
