Sending a Demand Letter by Certified Mail

Complete guide to sending your demand letter via USPS certified mail. Learn about return receipts, tracking, and why certified mail matters legally.

Why Certified Mail Matters

Certified mail isn't just fancy postage—it's legally significant documentation that:

Proves You Sent the Letter
The postal service creates an official record showing when your letter was mailed.

Proves They Received It
With return receipt requested, you get signed proof of delivery.

Eliminates "I Never Got It" Defense
In court, recipients can't claim they never received notice. You have their signature.

Shows Professionalism
Certified mail signals you're serious. The recipient must sign for it, drawing attention to its importance.

May Be Required
Some contracts and legal proceedings require certified mail notice.

Step-by-Step: How to Send Certified Mail

What You'll Need:

  • Your sealed, addressed letter

  • Visit to any USPS post office

  • Approximately $7-10 (postage + certified mail + return receipt)


At the Post Office:

  • Request Certified Mail with Return Receipt
Tell the clerk you need "certified mail with return receipt requested."
  • Fill Out the Forms
- White slip: Your receipt (you keep this) - Green card: Return receipt (goes back to you when letter is delivered)
  • Complete the Green Card
Write your address on the card. This is where the signed receipt will be mailed after delivery.
  • Pay the Fees
- First-class postage: $0.68+ - Certified mail fee: $4.15 - Return receipt: $3.55 - Total: approximately $8-10
  • Get Your Receipt
Keep the white receipt with the tracking number. You'll use this to track delivery.

Tracking Your Letter

Online Tracking:
Go to USPS.com and enter your tracking number. You'll see:

  • When it was accepted

  • When it's in transit

  • When it's delivered

  • Who signed for it


What to Look For:
  • "Delivered" - The letter arrived

  • "Refused" - Recipient declined to accept

  • "Unclaimed" - Nobody picked it up; it will be returned

  • "Return to Sender" - Various reasons; check the returned envelope


Timeline:
Certified mail typically takes 3-5 business days for delivery, similar to first-class mail.

Handling the Return Receipt

What You'll Get Back:
After delivery, the green card comes back to you with:

  • The delivery date

  • Signature of person who accepted

  • Printed or stamped address


Store It Safely
This is important legal evidence. File it with your copy of the demand letter.

If You Don't Get It Back
Sometimes return receipts are lost in the mail. Check your tracking online—the delivery info is also recorded there.

Electronic Return Receipt
For an extra fee ($2.62), you can get electronic return receipt, which sends you an email with the delivery info instead of the physical green card.

What If They Refuse or It's Returned?

"Refused" Status
If tracking shows "Refused," this is actually helpful. It proves:

  • They knew mail was coming for them

  • They deliberately chose not to accept it

  • They cannot claim ignorance


In court, refusal can be treated as actual notice.

"Unclaimed/Returned to Sender"
If no one picked it up:

  • Check that you used the correct address

  • Try their alternative address if you have one

  • Send a copy via regular mail (they may be avoiding certified mail)

  • Consider email as additional notification


Address Unknown/Moved
Try to find their current address through:
  • Public records

  • Social media

  • State Secretary of State (for businesses)

  • Skip tracing services (for debts)


Multiple Attempts
Document each attempt. Courts appreciate good-faith efforts to notify the other party.

Frequently Asked Questions

Is certified mail required for demand letters?

It's not legally required in most cases, but highly recommended. Certified mail provides proof of delivery that can be crucial if your case goes to court. Some contracts do specifically require certified mail for notices.

Can I send certified mail on Saturday?

Yes, you can mail certified letters on Saturday at post offices that are open. However, delivery is typically Monday-Saturday, and mail dropped on weekends may not be processed until Monday.

What if I need it delivered by a specific date?

For time-sensitive delivery, consider Priority Mail Express with certified mail, or use FedEx/UPS overnight. Standard certified mail takes 3-5 business days and cannot guarantee a specific delivery date.
