The purpose of this article is to identify and analyse the basic legal issues related to the protection of the secrecy of correspondence as a personality right in the era of modern technologies. Presently, the protection of the secrecy of correspondence by civil law is viewed in relation to privacy of communication. The judicature and jurisprudence identify a number of new legal issues that, in the absence of elementary normative concepts, play an important role in the protection of the secrecy of correspondence. A dogmatic method, which is a classical method of research in legal works, is used in the discussion. The analysis of legal provisions and views of the doctrine and the judicature allowed the author to present the nature of the violation of the secrecy of correspondence and to determine the direction of the optimum protection of this personality right. The importance of financial measures of protection is growing in the same way as in case of other personality rights. Currently, compensation is the basic means of protecting the secrecy of correspondence, although it is also possible to use non-financial protection measures. Societies highly appreciating a consumerist lifestyle believe that financial protection measures might lead to the mitigation of harm resulting from the violation of non-tangible values closely related to humanity and dignity.
