Should I send a demand letter by Certified Mail?

Yes, if you want USPS tracking and a mailing record.

Does Certified Mail make a demand letter legally binding?

No. It creates a mailing record. It does not make the demand stronger by itself.

Return receipt is useful when you want a copy of the delivery signature record. Electronic return receipt is often easier to store with your file.

Demand Letters

Send a demand letter by Certified Mail and keep the tracking record.

When it helps

You are giving a final written demand before escalation.

A contract, invoice, or policy requires written notice.

You want a dated mailing record before filing a claim or taking the next step.

The recipient has not responded to normal email or regular mail.

What to write

Your name, address, and preferred contact method.

The recipient name and mailing address exactly as you want it sent.

A concise statement of the issue, amount, deadline, and requested resolution.

Copies or references for invoices, agreements, photos, messages, or other supporting records.

A clear date on the letter and a copy saved for your records.

Certified Mail is strongest when the letter, address, tracking, and receipts are kept together.

Use the recipient address required by the contract if one is listed.

Keep the PDF you mailed, the tracking number, and the return receipt together.

If a contract names a notice method, follow it.

Keep the letter firm, factual, and easy to verify.

Threatening actions you do not intend to take.

Sending the only copy of a document instead of saving a final PDF first.

Using vague deadlines like "ASAP" instead of a specific date.

Assuming a delivery record proves the recipient agreed with your demand.

Upload the PDF. KiteCourier prints, mails, tracks, and keeps the records together.
