How to Send Certified Mail
Certified Mail can document when USPS accepted a letter and whether delivery was completed or attempted. Whether a particular notice must use it—and what the record proves—depends on the governing rule and facts.

How sources are checked →Why Certified Mail?
Certified Mail does not prove the contents of an envelope, but its postal records can help document:
- Acceptance record: USPS records accepting a numbered mailpiece
- Delivery record: USPS records delivery, an attempt, or another disposition
- Tracking: You can monitor delivery status online
- A record to preserve: A receipt you may choose to present if receipt becomes disputed
Florida landlord claim notices
Florida law (Fla. Stat. § 83.49) permits a landlord's claim notice by certified mail or by qualifying email under Florida Statutes section 83.505. A landlord who misses the statutory notice procedure can lose the right to impose a claim against the deposit, although the statute preserves a separate damages action. Check the current text and your facts.

Step-by-Step: Sending Certified Mail at the Post Office
What You Need
- Your demand letter (keep a copy for yourself)
- A standard white envelope
- Landlord's full name and address
- Your return address
- A way to pay (typically about $7-$12 for the options above)
Step 1: Prepare Your Letter
- Print your demand letter on plain paper
- Sign and date the letter
- Make a copy for your records
- Place the original in a standard envelope
- Write the landlord's name and address clearly
- Add your return address in the upper left corner
Step 2: At the Post Office
- Use a staffed USPS retail counter if you want help selecting the service; availability can vary by location
- Ask for Certified Mail and say whether you also want no return receipt, an electronic return receipt, or a paper return receipt
- If you choose the paper option, complete PS Form 3811 as directed by the clerk
- Check the destination and return addresses before USPS accepts the piece
- Pay the fee and keep the postmarked mailing receipt
Keep these records together
Keep the letter copy, attachments list, postal receipt, tracking number, and any electronic or paper return receipt together. The USPS record can document the mailpiece's acceptance and disposition, but it does not prove what was inside the envelope.
Step 3: Track Your Letter
- Go to USPS Tracking
- Enter your tracking number from the receipt
- Monitor for delivery, attempted delivery, refusal, or another disposition
- Print or screenshot the tracking confirmation
What if They Refuse Delivery?
USPS may record a refusal or unsuccessful delivery attempt. Preserve the record, but do not assume it legally counts as completed notice. Its effect depends on the statute, lease, address used, and other facts. The record can:
- Show the disposition USPS recorded
- Document that you used a numbered mailpiece and the address shown on your receipt
- Support your timeline if receipt or attempted delivery is later disputed
Should You Send It More Than One Way?
A second copy can create another record, but the legally required method—if any—controls. Depending on that rule, you might use:
- Certified Mail: creates USPS acceptance and disposition records
- First-Class Mail: a lower-cost option for sending a copy when you do not need Certified Mail acceptance or delivery records
- Email: creates a timestamped copy when electronic notice is permitted
Use the same dated document in each channel, preserve each record, and verify the governing notice rule before relying on any one method.
