Online Certified Mail from OnlineCertifiedMail.com is a web-based service that lets individuals and businesses send USPS Certified Mail entirely online. Users upload documents, enter recipient addresses, and pay securely; the service then prints, seals, and mails the letters via the United States Postal Service. This eliminates the need to visit a post office, purchase certified mail labels, or fill out forms manually. The service provides a certified mail tracking number immediately upon purchase, allowing senders to track their mail online through the website or USPS.com. Electronic Return Receipts are stored online, providing proof of delivery and recipient signatures. The platform is ideal for sending legal notices, recalls, pre-lien letters, and other important correspondence that requires proof of mailing and delivery. It reduces the time to send certified mail from days to under five minutes per letter, and a nearly 90% reduction in time for bulk mailings. With features like address books, multiple return addresses, and multi-user login, it streamlines certified mail processing for both occasional and high-volume users. For bulk mailings, LetterStream, the parent company, offers additional support. The service costs $11.49 for a single letter, with savings for larger quantities.

"Time Savings Over Post Office Visits!"
Extremely handy and a real time-saver, particularly for those in rural areas. A more explicit notification system would enhance an already excellent service. Getting the mail sent quicker is a definite plus.

"Very Convenient"
The simplicity justifies the slightly higher cost compared to the post office. I can move forward without wasting time, energy, or getting sidetracked. It's absolutely worth it! I believe the service will keep improving over time. The user experience is great, but the integration with automation software could use some refinement. It definitely saves time.

"The Quickest and Most Convenient Mailing Option!"
I've been using this service for about five years now! The entire process is seamless and straightforward. I never have to leave my office; I can send mail right from my computer. It's a blessing! There's nothing I dislike—if you don't like it, you're crazy! It's simply a more efficient and effective way to handle business.

"Simple and Effective"
Extremely straightforward to use. Your previous addresses are saved for easy selection, and letters get processed promptly. I haven't encountered any issues. I've been using the site for several months now. No more trips to the post office. With Online Certified Mail, sending certified letters is a breeze.
B
Business Owner
"Outstanding Service"
It's fast, straightforward, and safe. The platform is user-friendly, and if you're someone like me who goes to the post office and then forgets for days that you needed to send a certified letter, this solves that. The only hiccup is that if your credit card runs out of funds, they kick you off. The biggest plus is convenience. I live in Milwaukee, where there are only two post offices nearby. Whether you spend two minutes or a full hour in line is a gamble. Because of budget cuts at the post office, I've turned to this site. It's quick, simple, and convenient.
