Certified email. Legal proof, delivered.

How does our certified email work?
It works exactly like email — because it is email. The proof happens automatically, behind the scenes.
Upload & compose
Attach your document, write a subject line and message — just like any email. PDF, DOC, JPG and 20+ formats supported.
Send to any inbox
Your recipient gets a normal email — no account, no software, no portal login. It works with Gmail, Outlook, anything.
Manage your evidence
Track delivery and opens in real time, and download the tamper-proof certified receipt for every send — timestamped evidence of content, delivery and opens.
Why teams make the switch
Everything a courier or registered letter gives you — without the post office, the wait, or the cost.
Reliable
Secure your documents. Receipts are structured as evidence: content, timestamp and delivery in one tamper-evident record.
Fast
Send emails in no time. A certified send takes the same 60 seconds as a regular email — delivered in seconds, not days.
Practical
Simplify preparation and distribution. Your message lands in their normal inbox — no portals, no accounts, no friction.
Compliant
256-bit AES in transit and at rest, with HIPAA, SOC 2 Type II and a BAA available — safe for sensitive documents.
Cheap
Eliminate shipping costs. Companies switching from registered post and couriers cut sending costs by up to 87%.
Ecological
Minimize paper consumption. No printing, no envelopes, no courier miles — every notification fully digital.
The fastest way to send with certainty.
How Certified Email stacks up against the old ways of proving delivery.
| FAXER CERTIFIED EMAIL | Registered mail | Regular email | |
|---|---|---|---|
| Delivery time | Seconds | 3–10 days | Seconds |
| Proof of delivery | Timestamped receipt | Signature card | None |
| Proof of content | Cryptographic hash | Envelope only | Disputable |
| Proof of opens | Human-verified | No | Unreliable pixels |
| Cost per send | From $0.99 · first one free | $9–25 + trip to post office | Free, but proves nothing |
| Recipient effort | None — normal inbox | Must sign in person | None |
