Mail any preliminary notice or mechanic lien. Get court-ready proof, automatically.
NLB Mailing lets you upload a document, choose First Class or Certified Mail, and click send. Every mailing comes back with a time-stamped Certificate of Mailing and Certificate of Delivery, merged with a copy of what you sent and archived for the day a deadline is challenged.
How it works
From your desk to the mailbox in four steps
- 1
Upload
Upload one document or a thousand, straight from your computer or the National Lien & Bond platform. Preliminary notices, Section 24 notices, mechanic's liens, demands, anything that has to go in the mail.
- 2
Send
Choose USPS First Class, Certified Mail, or Priority Express, enter who it goes to, and click send. No documents to print, no envelopes to stuff, no trips to the post office.
- 3
Track
Track every mailing in real time from one place. See exactly when your document was mailed, delivered, and signed for, without calling the post office or chasing a green card.
- 4
Verify
Time-stamped proof of mailing and delivery is merged with a copy of the document you sent and archived in your account. Share a verified mailing with a client or opposing party in one click.
Why it works
Built for deadlines, priced for volume
Stop losing hours to printing, stuffing, and the post office. Send one notice or a whole project's worth from a single screen, and let the proof generate itself. Every send is statute-ready service with the kind of proof that decides whether a lien survives a challenge.

Electronic and physical proof it arrived

Proof that holds up
Every certificate is hashed, encrypted, and tamper-proof. It is not a static PDF you hope nobody questions. It is a live record an authorized party can verify, online, on its own.
The whole record
A certificate covers the entire mailing: who sent it, who received it, what was enclosed, and when each step happened.
Real time
When a new event is added to the record, NLB Mailing issues a fresh hashed certificate and retires the old one, so the proof is always current.
Verifiable
Authorized parties can confirm a certificate's status and authenticity online through the Digital Evidence Archive.
Why proof of service wins lien cases
Most lien statutes require you to serve notices a specific way and keep proof that you did. A missing or defective proof of service can sink an otherwise valid lien, no matter how good the claim is. NLB Mailing makes service compliant and your proof admissible, so the deadline you met is the deadline you can prove.
