Which landlord notices can go by Certified Mail, and which ones cannot
Most routine landlord notices — lease violation warnings, rent increase letters where your state allows mailing, non-renewal notices, deposit itemizations and letters to former tenants — can go by USPS Certified Mail, and it gives you a mailing date, a tracking history and, with the electronic return receipt, a signature. The notices that start an eviction are different: many states list the methods of service, and certified mail alone is often not one of them. California’s Code of Civil Procedure section 1162, for example, allows personal delivery, substituted service or posting and mailing for its eviction notices. Serve those the way the statute says, and use certified mail as an extra record on top.
Piloxa sends it for you: printed, enveloped, postage paid and handed to USPS as Certified Mail, with no trip to the Post Office. Your first letter is $9.95 all in: one or two pages by Certified Mail with USPS tracking, with printing, the envelope, postage and the certified fee included. You see the exact pages, the recipient and one total before you pay. No subscription.
In short
For landlords and property managers who send the same kinds of notices to many tenants, Piloxa mails each one by USPS Certified Mail and keeps the exact notice, the printed address and the tracking together, one record per letter.
Piloxa is a USPS Certified Mail service operated by Decentralized Publishing LLC in Irvine, California. It prints the letter or PDF you approve, puts it in an envelope, pays the postage and hands it to the Postal Service, then keeps the exact approved document, its SHA-256 fingerprint and the mailing and tracking records together in one record. Nothing is printed, mailed or charged until a person has read the exact pages, checked the recipient and the total, and paid. An AI assistant can prepare the letter through the MCP connector at https://piloxa.com/mcp or the HTTP API described at https://piloxa.com/openapi.json; either way it only gets back a review link for the person to open.
The notices landlords send, and how each one is usually delivered
| Notice | What usually governs delivery | Is Certified Mail a good fit? |
|---|---|---|
| Notice of entry | State law sets a minimum advance notice (24 hours is a common figure) and often lists acceptable methods, including posting or handing it over. | Rarely. A letter takes two to five days or so to arrive, so a mailed entry notice has to go out well ahead of the visit. Hand delivery or the method your lease names is usually simpler. |
| Lease violation warning (informal) | The lease. A plain letter asking a tenant to stop a behavior is not a statutory notice. | Yes. It creates a dated record that the tenant was told, which matters if the problem continues. |
| Cure-or-quit or pay-or-quit notice | State eviction statutes, which often list specific service methods. | Not on its own in many states. Serve it as the statute requires; add a certified copy if you want the extra record. See notices to vacate and eviction notices. |
| Rent increase | State and local law set the notice period, which can be longer for larger increases, and sometimes the method. | Often, where mailing is a permitted method. Check whether your state adds days for a mailed notice. |
| Non-renewal or termination of a month-to-month tenancy | The lease’s notice clause and the state statute. California Civil Code 1946.1 sets 30 days for a tenancy under a year and 60 days for one of a year or more, and just-cause rules (Civil Code 1946.2) may also apply. | Often. Count the notice period from the date the statute or lease uses, not the day you mail it. |
| Security deposit itemization | State deposit statutes, with a deadline after move-out (21 days in California under Civil Code 1950.5). | Yes. It proves you sent the itemization before the deadline, to the forwarding address the tenant gave. |
| Demand to a former tenant | No special rule. It is an ordinary demand letter. | Yes. See rent demand letters. |
The pattern is simple. Where the law only says “give written notice”, certified mail is a strong way to do it. Where the law lists how a notice must be served, follow the list first. Where your lease names a notice address or a method, the lease applies to you as well as to the tenant.
When certified mail is enough, and when it is not
Certified mail is usually enough when the notice is informational, contractual or a demand: the tenant has to know, and you have to be able to show they were told. It is not enough when a statute requires a particular kind of service and lists the methods, which is typical of the notices that come before an eviction lawsuit. Under California’s CCP 1162, for instance, the three methods are handing the notice to the tenant, leaving it with a suitable person at the residence or business and mailing a copy, or posting it on the premises and mailing a copy. A certified letter by itself is not on that list, so a tenant can challenge the notice, and an eviction case can fail on it.
Two postal facts matter for any tenant notice. First, unless you buy Restricted Delivery (Piloxa does not offer it), USPS can deliver to a family member, employee or anyone authorized to receive the tenant’s mail, so the signature on the receipt may not be the tenant’s (who can sign). Second, a tenant can refuse the letter or leave it unclaimed; USPS holds it and returns it after 15 days. Both outcomes are recorded, and what they mean legally depends on your state (unclaimed certified mail).
Sample lease violation letter
Sample — an informal warning, not a statutory cure-or-quit notice
[Landlord or management company name]
[Address]
[City, State ZIP]
[Date]
[Tenant full name(s)]
[Unit address]
[City, State ZIP]
Re: Lease violation — [unit address], lease dated [date]
Dear [Tenant name],
Section [number] of your lease says: “[quote the clause].” On [date(s)], [state the facts plainly: what happened, who observed it, any complaint or photograph].
Please [state the specific correction, e.g. remove the vehicle from the fire lane / stop running the business from the unit] by [calendar date].
If the violation continues after that date, we will serve the formal notice your state’s law requires, which can lead to termination of the tenancy. We prefer to resolve it now. You can reach [name] at [phone or email].
Sincerely,
[Name, title]
If the warning is meant to be the legal notice itself, use the form, contents and service method your state requires instead of this sample.
Keeping a record across many tenants
A property manager’s problem is rarely one letter. It is proving, a year later, which version of a notice went to which unit on which date. A folder of post office receipts does not answer that, because the receipt names an article number, not a document. Piloxa keeps one record per letter: the exact notice you approved and its SHA-256 fingerprint, the recipient address as printed after a postal address check, the service bought, when it was handed over, and each USPS scan as it is reported. With the electronic return receipt, the signature record is added once USPS releases it. A filled-in sample record shows what that looks like, including the gaps marked “no record yet”.
Each notice is prepared, reviewed and paid individually, so the person approving it sees the exact pages and the address for every tenant. There is no subscription and no minimum. Firms sending notices every month can do so one at a time from the web app or through an assistant with the connector; the business page covers volume sending and what is not automated yet.
Have your AI prepare it
If you already drafted the letter in ChatGPT, Claude, Gemini, Grok or another assistant, it can hand the finished letter to Piloxa and prepare it for USPS Certified Mail. Ask it in plain words, for example: Send this notice to my tenant by Certified Mail with the electronic return receipt.
The connector address is https://piloxa.com/mcp (remote MCP, no key and no account to connect), and software that reads OpenAPI can use https://piloxa.com/openapi.json. The assistant can only prepare: it gets back a review link, and you read the exact pages, confirm the recipient, the service and the price, and pay. Nothing is printed, mailed or charged before that. What an assistant can and cannot do with Piloxa.

Questions people ask
Can a landlord send notices by certified mail?
Yes, for most routine notices, and it is a good way to prove the tenant was told. For eviction notices, check your state’s service statute first: many list specific methods, and certified mail alone is often not one of them.
Does the tenant have to sign for it?
Someone has to sign or the letter is not delivered, but it need not be the tenant. Without Restricted Delivery, USPS can deliver to a family member, an employee or an authorized agent. Piloxa does not offer Restricted Delivery.
What if the tenant refuses or never picks it up?
USPS records the refusal or the unclaimed notice and returns the letter. Some statutes and leases treat a properly mailed notice as given regardless; others do not. That is one reason to serve statutory notices by the listed method and use certified mail as the extra record.
Is there a bulk option for property managers?
Each notice is reviewed and paid individually, with no subscription or minimum. For regular volume, the business page explains what is available and what is not automated yet.
What does it cost per notice?
$12.97 all in for a one-page notice by Certified Mail with tracking, or $15.97 with the electronic return receipt. Printing, envelope and postage are included.
