GUIDE · CERTIFIED MAIL

Send a certified letter to your landlord without the post office.

Write the letter in 9tenant, from a plain-English template or from scratch. We print it, mail it USPS Certified with delivery tracking, and file the letter and receipt in your records. $25 flat, postage and return receipt included. You never stand in line.

Why put it in writing at all

Most tenant problems are won or lost on the record. A phone call evaporates. A certified letter creates a dated fact: on this day, you were told, and you signed for it. Landlords who ignore texts tend to answer certified mail, because they know what that envelope means if the dispute ever lands in front of anyone.

The templates

Seven starting points for the situations renters actually hit. You edit the content and you sign it:

  • Notice to Repair: a dated, trackable repair request.
  • Notice of Habitability Issue: heat, water, pests, and other conditions that affect livability.
  • Demand for Security Deposit Return: with Massachusetts statutory wording when your unit is in MA.
  • Rent Receipt Request: for landlords who take cash and give nothing back.
  • Notice of Improper Entry: when the landlord comes in without proper notice.
  • Notice of Retaliation Concern: puts a paper trail under a sudden rent hike or notice after you complained.
  • Custom letter: you write it, we mail it the same way.

What happens when you hit send

  1. Your letter is rendered to a dated PDF with your name and addresses.
  2. It is printed, enveloped, and handed to USPS as Certified Mail.
  3. Tracking scans are recorded through to delivery, including the return receipt.
  4. The letter, the payment receipt, and the delivery history are filed in your 9tenant records automatically, next to the photos and correspondence you already keep there.

What it costs

The app is free. A certified letter is $25. That covers printing, the envelope, USPS Certified postage, the return receipt, and tracking. No subscription. You pay only when you mail something.

Questions people ask

Do I have to go to the post office?+
No. You write the letter in 9tenant and we handle printing, the envelope, USPS Certified postage, and the return receipt.
How do I know the letter was delivered?+
USPS tracking scans are recorded against your letter as it moves, through to delivery. The tracking history is stored with the letter in your records.
Why certified mail instead of email or text?+
Certified mail produces a dated, third-party record that the letter was sent and delivered. In a dispute, 'I emailed them' is an assertion. A certified mail receipt is evidence. Many statutes and leases also expect written notice.
Is the letter reviewed or approved by anyone?+
No. The templates are plain-English starting points. You write the actual content and sign your name. 9tenant is a mailing and record-keeping tool, not a law firm, and nothing we provide is legal advice.
