In Human Resources, communication isn’t just paperwork—it’s legal documentation. From final paycheck notices and termination letters to WARN Act notifications and employment dispute records, how you deliver key information matters. When deadlines, documentation, and proof of delivery are required, Certified Mail becomes the gold standard.
Yet, many HR teams make common mistakes when sending Certified Mail. Mistakes that can result in compliance issues, legal risk, or delayed delivery.
At Certified Mail Labels, we work with HR departments, employment attorneys, and corporate compliance teams to help them send Certified Mail online. Easily, affordably, and accurately—if you're responsible for staying compliant, this guide is for you.
Why HR Teams Rely on Certified Mail
Certified Mail through the United States Postal Service (USPS) offers proof of mailing, tracking, and delivery confirmation. All requirements that are often mandated by state and federal labor laws.
USPS Certified Mail is commonly used by HR teams to send:
- Termination letters and notices
- Final paycheck notifications (as required by labor codes)
- Layoff notices under the WARN Act
- COBRA continuation letters
- Employment contract disputes or legal updates
Unlike email or standard mail, Certified Mail provides legally accepted proof that a letter was sent and received. Thus, protecting your organization in the event of a dispute.
Top Certified Mail Mistakes HR Departments Make
Let’s walk through the most common Certified Mail errors HR teams face—and how Certified Mail Labels helps eliminate them.
1. Delaying Mailings by Relying on the Post Office
Many HR departments still print termination letters or WARN notices, walk them to the mailroom, and then head to the Post Office. That process is time-consuming, prone to delays, and exposes your team to manual errors.
With Certified Mail Labels, you can skip the trip to the Post Office. Easily create USPS Certified Mail, Priority Mail, and Express Mail labels with live USPS Postage online. Send USPS mail from the comfort of your home of office. Plus, save $3.15 on postage for each Certified Mail green card receipt.

2. Failing to Keep Proof of Mailing or Delivery
Labor regulations often require documentation that a notice was delivered. If your team can’t prove a termination letter or final check notice was received, you may face legal exposure.
Certified Mail offers you instant USPS tracking numbers, delivery confirmations, and an optional Return Receipt Signature. Plus, every letter sent with Certified Mail Labels is stored in your 10-year compliance archive—free.
3. Using the Wrong Mailing Format
Improper forms, handwritten green cards, or incorrect envelope placement can cause delays or even returned mail.
Certified Mail Labels offers USPS-approved formats, smart address validation, and the ability to use standard or preprinted Certified Mail envelopes. Just fold your letter, insert it, and mail.
4. Paying Too Much for Each Mailing
With USPS retail rates rising—again in July 2025—sending Certified Mail at the counter can quickly add up. This affects HR teams sending dozens (or hundreds) of notices during events like layoffs or benefit changes.
Certified Mail Labels customers save up to $3.15 per mailing compared to traditional USPS green card costs.
5. Not Using Return Receipts When They Matter Most
If a dispute arises over whether an employee received their termination letter, your defense may rely on more than just tracking scans—it could require a signature receipt.
We offer Return Receipt Electronic Signatures, which you can access from your dashboard, anytime. This report shows the recipient's signature on the mailing receipt and serves as legal proof it reached the intended recipient.
Certified Mail for WARN Act Compliance
Under the Worker Adjustment and Retraining Notification (WARN) Act, employers must provide 60-day advance notice to employees affected by mass layoffs or plant closings. That notice must be delivered and documented.
Certified Mail service is one of the most trusted methods to comply with these rules, particularly when physical date of mailing and proof of delivery is required.
Certified Mail Labels helps organizations manage WARN mailings efficiently with batch label creation, secure tracking, and automated delivery notifications.
