See certified channelsSend the document and get the signature back in minutes, with verified identity and full evidence.
Online contractingProve a document existed at an exact moment with qualified timestamping.
TimestampingConfirm who is on the other side with ID document reading and facial biometrics.
Identity verificationFour certified channels so your message arrives, gets read and goes on record: full content, delivery and the exact moment.
An SMS gets opened within seconds and needs no internet connection or installation. Ideal for debt claims, expiry notices and urgent communications with evidentiary value.
Send the email with its attachments and receive a certificate recording the full content, delivery to the destination server and every opening. Perfect for terms, quotes and formal demands.
Messages with your verified brand, images and buttons, right in the phone's own messaging app. And with the same guarantee: a report of content, delivery and reading.
Not just one message: the complete conversation, replies included, is captured and sealed. The natural way to agree on terms over the channel your customers already use every day.
Upload the document, choose who signs and through which channel. Signers open it on their phone, review it and sign in a couple of taps. You get the completed contract with its evidence report.
A quote, a piece of work, an agreement, a file: any document can be sealed with qualified proof of date through Qualified Timestamping, recognized across the European Union.
Before a signature or a new customer sign-up, confirm who they are: ID document capture, automatic checks and biometric face matching. No friction, no paperwork.
Every sending, signature or verification generates a PDF certificate designed to be understood at a glance and to hold up before whoever needs to see it.
The complete text of the message or document, attachments included, exactly as it was sent.
Date and time of every milestone, fixed with Qualified Timestamping.
Confirmations from the carriers and destination servers: delivered, opened, replied.
Sender, recipient and, where applicable, OTP or biometric verification of the signer.
A cryptographic hash of the content: any later alteration is immediately exposed.
Your reports are kept in custody, ready to download or verify whenever you need them.
Certificates are sealed by two qualified trust service providers (Mensatek and the FNMT) — the guarantee that the evidence never depends on a single party.

Integrate certified notifications, contract signing, timestamping or identity verification into your ERP, CRM or application. A REST API with clear documentation, test environments and real-time status webhooks.
We went from chasing contracts for a week to having them signed the same morning. And when a customer disputed a notification, the report ended the argument.
We integrated Certified SMS through the API in two afternoons. The documentation is one of the few you actually understand on the first read.
What I value most is the phone line: you call and someone who actually knows picks up. With the service we had before, that was unthinkable.
We operate under the eIDAS Regulation (EU) 910/2014, which recognizes the legal and evidentiary effect of electronic signatures and seals and of certified electronic delivery services. Every operation generates an evidence report sealed with qualified proof of date that you can submit in court or in administrative proceedings.
The message the recipient receives is the same; the difference is that we act as a trusted third party: we record the full content, the recipient, the delivery and the exact moment, and gather it all in a sealed report. A regular sending leaves no proof you can rely on later.
No. They receive the SMS, email, RCS or WhatsApp on their usual phone or inbox, and if they need to sign they do it from their phone's browser, with no apps and no registrations. The less friction, the more notifications get read and the more contracts get signed.
We work with prepaid credits: you buy the ones you need and spend them as you go — no monthly fees, no minimums, no lock-in. You can check the per-service rates on the pricing page, and when you create your account you get free trial credits for your first sendings.
Yes. Every service is available through a REST API: sending certified notifications, contract signing, timestamps and identity verification, with webhooks that report every status change. And if you'd rather not write code, the web platform does all the same things.
On infrastructure managed by us in accordance with the GDPR and our ISO 27001 certification. Your reports are kept in custody and you can download or verify them whenever you like from your dashboard.
Create your account in two minutes and send your first certified notification or your first contract today with free trial credits.
