Email Certification: Security and Legal Validity with MassCert
What is email certification?
Email certification is a service that guarantees the integrity, authenticity, and legal validity of an email. It allows you to legally prove that an email was sent, received, and that its content was not altered. This certification turns the email into valid evidence in front of third parties, including in court.
Why is it important to certify an email?
In a digital environment where more and more procedures and communications happen via email, having legal proof of the sending and content can make the difference in a legal dispute, claim, or court case. Email certification protects you in situations such as:
Contractual and legal notifications
Formal claims
Communications with clients, suppliers, or employees
Conflict resolution or unpaid invoices
In short, it provides legal security and prevents issues with interpretation or rejection of evidence in legal proceedings.
