What it is
Proof of sending and receipt, with legal force.
Every message sent as Registered Email generates a qualified certificate proving who sent it, to whom, when and with what content, and whether it was delivered and read. It is the digital equivalent of a registered letter with acknowledgement of receipt, but instant and at a fraction of the cost.
Sealed proof
A qualified certificate for each message, with a date and time no one can alter.
No one can say "I didn't receive it"
Delivery and reading are proven: the recipient cannot deny them (known as non-repudiation).
Stands up in court
Admissible as evidence in any court in the European Union.
Backed by law
European eIDAS Regulation and Decree-Law No. 12/2021.
Comparison
Same legal validity. No trips to the post office.
All the evidential value of registered mail with acknowledgement of receipt, without queues, without paper and without waiting days.

When it makes a difference
For communications that need proof.
Whenever you need to demonstrate, with legal validity, that a message was sent and received.
Law firms
Formal demands, notifications and communications with evidential value, without trips to the post office.
Insurance
Communications with policyholders and third parties, with instant proof of sending and reading.
Real estate
Lease terminations and contractual communications with a sealed date.
Condominiums and companies
Meeting notices and communications between shareholders or unit owners, admissible in court.
Utilities
Customer notifications (water, energy, telecoms) with proof of receipt.
Procedures
Contract terminations and defaults, with a qualified certificate for each message.
Do the maths
Two registered letters a week already cost more than this.
A registered letter with acknowledgement of receipt costs between €3 and €5, plus printing, the envelope and the trip to the post office. Registered Email costs €27.50 per user/month. If your company sends more than two registered letters a week, you are paying more for the old process, and waiting days for what is proven here in seconds.
How it works
Three steps, no hassle.
The experience is that of a normal email: the legal proof happens behind the scenes.
Write as usual
The message is composed in webmail and the Registered Email option is switched on before sending.
Sooma seals the message
A qualified certificate is generated with the date, time, recipient and content, with a timestamp.
The proof remains
Proof of sending and, later, of delivery and reading is available, admissible in court.
Frequently asked questions
Questions about legal validity
What lawyers, managers and building managers ask us before signing up.
Does Registered Email really have legal validity?
Yes. It is based on the European eIDAS Regulation and Decree-Law No. 12/2021, which govern electronic registered delivery services. The qualified certificate is admissible as evidence in court in the European Union.
Is it equivalent to registered mail with acknowledgement of receipt?
Yes, with the same evidential function for sending and receipt, and the advantage of being instant, with no trips and at a fraction of the cost.
Does the recipient need a Sooma account?
No. It works with any recipient; proof of delivery and reading is generated by the service.
And if the recipient doesn't open the message?
The certificate proves sending and delivery to the recipient's mailbox, with a sealed date and time, just as an acknowledgement of receipt proves delivery of a letter, whether or not the recipient reads it.
Can I use Registered Email only occasionally?
Yes. Registered sending is switched on message by message; the rest of the company's email works as usual.
How much does it cost?
The Registered Email plan includes a 50 GB mailbox and legal certification for €27.50 per user/month, with a qualified certificate for each message. See the pricing page for details.
