Should you send your deposit demand letter by certified mail?
The short answer
Yes — send it certified, and keep the receipt. Not because the law makes you: no deposit statute we have checked against a primary source requires it. Send it certified because proof of mailing plus a delivery record is the same evidence a small-claims filing asks for when it asks how and when you notified your landlord.
Certified Mail adds two records to an ordinary letter: a mailing receipt the clerk postmarks, and a Postal Service record showing when it was delivered or that a delivery attempt was made. Add Return Receipt and you also get the signature of whoever accepted it. Nothing about the envelope changes the law. What changes is whether you can show the date.
The limit
What certified mail does not prove
It proves the envelope moved. It does not prove what was inside it, and it says nothing about the condition you left the unit in. Those are separate jobs. The condition of the unit is what your move-out photos are for — if you have not taken them yet, the move-out photo checklist is the room-by-room version you can use on the day.
What the statutes say
The writing requirement runs toward you, not away from you
Read the first two rows together. In every jurisdiction DepositHawk has checked against a primary statutory source, the landlord is the one who has to put something in writing — an itemized statement, inside a fixed window. None of those statutes tells you how to send your own letter. That half is left entirely to you, which is why the proof is worth buying rather than assuming.
The last row is why you keep the receipt rather than the memory of it. Filing windows in those jurisdictions run for years, not months. A postmark from this month has to still be findable when you need it.
Your own state's deadline, and the full 51-jurisdiction table, are in the deposit return deadline guide.
The comparison
Regular mail, certified, or certified with return receipt?
The prices below are the Postal Service's, read off usps.com on September 20, 2026. They change on their own schedule — check before you go.
A regular stamp
| Cost | \$0.82, more if the envelope runs over an ounce |
|---|---|
| Proof you get | None. No record that you sent it, no record that anything arrived. |
| In small claims | Your word against theirs about whether the letter was ever sent. That is a bad place to start an argument you could have avoided for a few dollars. |
Certified Mail
| Cost | $5.55 on top of postage |
|---|---|
| Proof you get | A mailing receipt with a tracking number, plus a Postal Service record showing when it was delivered or that a delivery attempt was made. |
| In small claims | Fixes the date the letter went out and the date it reached them. An attempted delivery is recorded too, which is its own answer to a landlord who says nothing ever came. |
Certified Mail + Return Receipt
| Cost | $5.55 plus $2.91 for the emailed receipt, or $4.65 for the mailed card, on top of postage |
|---|---|
| Proof you get | Everything above, plus a delivery record showing the signature of whoever accepted it. |
| In small claims | Adds who signed for it. Worth the difference when the lease names a management company or an LLC and you expect an argument about which office got the letter. |
If you are picking one and moving on: certified with the emailed return receipt. It is the cheaper of the two ways to end up holding a signature, and it arrives in your inbox instead of as a card you have to file somewhere you will remember.
At the counter
How do you send a demand letter by certified mail?
- 01Print two copies. One goes in the envelope; the other stays with you, with the receipt stapled to it.
- 02Address it the way the lease names them. If the lease names a management company or an LLC, that is the addressee — and if you also have a name for the individual, send a second copy there.
- 03Ask for Certified Mail at the counter and fill out the certified receipt. Hand the letter to a clerk instead of dropping it in a box, so the sender's receipt comes back postmarked.
- 04Decide about Return Receipt before you pay. It is a separate fee on top of certified, and the emailed version costs less than the mailed card.
- 05Photograph the stamped receipt before you walk out. Paper gets lost, and the tracking number is the entire point of that piece of paper.
- 06Save the tracking page as a PDF once it stops moving. A screenshot of a live web page is not a record you control.
Before you pay for postage, read the letter once more for what it actually says. The free letter checker compares a letter you paste in against your state's deposit statute, return deadline and penalty, and tells you what is missing. Nothing to sign up for.

●Frequently Asked Questions
Frequently Asked Questions
Does a demand letter need to be certified?
No. None of the security-deposit statutes DepositHawk has checked against a primary source makes certified mail a condition of asking for your money. You can hand the letter over, email it, or drop it in a mailbox and the demand still counts. What certified mail changes is not whether the demand is valid — it is whether you can show the date it went out and the date it landed. That part costs a few dollars now and cannot be recreated later.
What counts as proof of mailing for a security deposit letter?
Two separate things, and you want both. The postmarked mailing receipt the clerk hands back is proof that you sent it, on that date. The tracking record is proof of what happened next — delivered, or attempted. Photograph the receipt the day you mail it and save the tracking page as a PDF once it stops moving. A photo of a sealed envelope on your kitchen table proves nothing, and a screenshot of a page that may not exist in three years is not much better.
My landlord isn't responding to calls or texts — now what?
Silence is normal in these disputes and it does not mean you are out of options. Put it in writing, because calls and texts leave you with little you can show later, and send the writing in a way that leaves a record — that is the whole argument for certified mail. Then find out whether their deadline has already run. Every state sets one, and a landlord who has blown it is in a different position than one who is merely slow.
Is this a scam?
This guide is free and there is nothing to sign up for. Where DepositHawk charges is the letter itself. One-time $19 or $39. No subscription. No auto-renewal. No trial that quietly becomes a charge. That is a deliberate contrast with how this category usually works.
