About eEvidence’s registered delivery service

1. About eEvidence

Since 2012, more than 10,000 customers have trusted the service to securely send more than 60 million registered communications.

eEvidence Registered Email

eEvidence relies on registered email as the channel for sending your messages – the digital equivalent of a classic certified mail. This has multiple advantages for you:

  • Easier and faster to send
  • Immediate certified delivery
  • Increased traceability (you’re in full control: know if it has been sent, delivered and at what exact time)
  • Far more affordable (save up to +90%)
  • Legally valid and court-admissible in the United States, Canada, United Kingdom, Europe, among other regions.
  • Recipients cannot decline it deliberately, as it happens with certified notices in paper. eEvidence’s patented method doesn’t require the intervention of the recipient to certify email delivery, this is done automatically.
  • Invisible for the recipients: eEvidence’s exclusive feature that allows you to register your messages without alerting the recipients, they receive an ordinary email.

Registered email has many different use cases, one of them being the digitization of traditional certified communications such as a certified letter.

2. How it works

eEvidence’s method is very simple to understand and “similar” to sending a certified letter:

  1. When you send a certified email, eEvidence takes care of sending it and certifies its delivery, acting like a courier or postal service. The recipient doesn’t have to do anything, the registered delivery receipt is automatically issued.
  2. Once delivered, eEvidence issues an electronic evidence receipt. This is a certified audit trail that contains all the data of the transmission of the message, the exact time on which it was sent and delivered, the exact content of the message as well as any of the attached documents. It’s electronically signed and sealed to protect its integrity and verifies that the email and its contents have not been altered during transmission.
  3. A few seconds later, eEvidence emails you a delivery confirmation with the delivery receipt (court-admissible evidence) attached and stores it securely for a minimum of 5 years in the cloud. Access and download it anytime, anywhere.
  4. In case of a dispute or if you need to bring evidence in court, eEvidence’s electronic receipt is the proof you need. Like a postal registered mail, a registered email by eEvidence legally proves content and delivery of a your communications with irrefutable evidences.

Legal proof of email

3. Legal value

Registered email is considered the online equivalent to the classic postal certified mail and is legally recognized across the globe. The evidence provided by eEvidence’s registered delivery service has probative and evidentiary value and is court-admissible in most regions.

eEvidence complies with international regulations such as the ESIGN and UETA Acts (United States) or the Regulation (EU) Nº910/2014 (eIDAS). These ensure non-discrimination as evidence in court vis-à-vis paper equivalent.

Finally, you should keep in mind that eEvidence, as well as any other service, does not substitute the work of a legal professional, who will be able to provide you with legal advice, recommend the appropriate channel or help you draft your message and documents.
