Certifies the sending
You use your usual email and add an address in copy. It proves what you sent, to whom and when.
Proves: that you sent the message, its content and the sending date.
Reliable notification · eIDAS
Prove that your message was received and read
With a normal email you never know if it was opened. SafeStamper Notify sends your communication as a trusted third party and certifies delivery, opening, attachment download and the recipient's reply, with date, time and IP. The proof of receipt required by demands, claims and the new ADR procedures.
By email or SMS · it is not sent from your inbox, but from Safe Stamper · eIDAS backing.
Two different proofs
Do you need to prove sending or receipt?
They are two complementary pieces of evidence. Choose according to what you need to prove; many companies use both.
Certifies receipt and reading
We send the message as a trusted third party, with a link to read it. It proves that it arrived and that it was opened.
Proves: that the recipient received, opened and, where applicable, downloaded and replied.

ADR and Confidential Binding Offer
Since Organic Law 1/2025, before filing a civil or commercial lawsuit you must attempt an Adequate Dispute Resolution Method (ADR). The Confidential Binding Offer is the most used one, and the law requires sending it by a means that proves its receipt by the other party.
⚖ OL 1/2025 · procedural requirement- Proves that the offer or the invitation to negotiate was received and opened, with a certain date.
- Silence within the legal term equals rejection: the proof of receipt enables you to sue.
- A conventional email is not enough; courts have already dismissed lawsuits lacking proof of receipt.
Confidentiality respected. For the lawsuit to be admitted it is enough to prove the sending and receipt, not the content of the offer —which is confidential—. Notify documents receipt independently of the content, which is kept safe.
How it fits the procedural requirement
1
You send the CBO via NotifyThe recipient receives the notification and accesses the content through the link.
2
Receipt is certifiedDelivery, opening, date and access IP are recorded.
3
The legal term elapsesIf there is no express acceptance, silence counts as rejection.
4
You attach the proofYou provide the proof of sending and receipt to the lawsuit, without revealing the content.
The backing that gives confidence

Each notification generates a certification with its status, hosted and verifiable, with Safe Stamper's evidentiary technology.

- Trusted third party: the sending and hosting of the content by Safe Stamper allow each access to be proven independently.
- Qualified time stamp in accordance with the European eIDAS regulation (EU 910/2014).
- Reading traceability: accesses, IP, exact date and time and attachment download.
- Content integrity: digital fingerprint (hash) and daily audit on the Ethereum blockchain.
- Evidentiary value: certificates admissible in courts and arbitrations.

Frequently asked questions
Common questions
Is it valid to meet the ADR requirement of Law 1/2025?
To go to court in civil and commercial matters you must first attempt an ADR, such as the Confidential Binding Offer, sent by a means that proves its receipt. Notify certifies that receipt with a certain date, independently of the content, which is confidential. The final assessment corresponds, like any evidence, to the court.
How is it different from Safe Stamper Mail?
Mail certifies the sending from your own inbox (what you sent and when). Notify certifies receipt and reading: the message is sent by Safe Stamper and it is proven that the recipient opened it.
What exactly gets certified?
The sending, the reading, the download of the attachment and the recipient's reply, with date, time and IP of access.
Does the recipient have to do anything?
Yes: they receive an email or SMS with a link and must click it to read the content. That access is what makes it possible to certify the reading.
Can I tell if they have not read it?
Yes. You see the status in your account, you can resend the notice and set a closing date if it is not read in time.
Through which channels is it sent?
By email or SMS, as you prefer for each recipient. The service is available in Spanish and English.
Do the notifications comply with NOM-151 in Mexico?
Yes. For users in Mexico, each certified notification includes the Record of Conservation of Data Messages in accordance with NOM-151, issued through SeguriData (PSC accredited by the Ministry of Economy), in the same act and at no additional cost. Also available for organizations from other countries with activity in that market.
What validity does it have as evidence?
It is technological evidence with evidentiary value, with a qualified eIDAS time stamp and a digital fingerprint. Its assessment corresponds, like any evidence, to the body that analyzes it.
Let "it never reached me" stop being an excuse
Send your next important communication as a certified notification and have proof that it arrived, was read and when.
SafeStamper Notify is a service of Safe Creative, a global certifier and trusted third party, operating since 2007. Certificates are technological evidence with evidentiary capacity; their assessment depends on the context, jurisdiction and judgement of the body or party analyzing them, and they do not replace legal advice when necessary.
