What is the Message Management System (“İYS”)?

Due to the difficulties in the implementation of commercial communication processes, Republic of Turkey Ministry of Trade has decided to establish a national commercial electronic communication management system (İYS, elektronik ileti yönetim sistemi) and has authorized the Turkish Union of Chambers and Exchange Commodities to that end. İYS attained its legal ground with the amendments introduced by the Regulation on the Amendment to the Regulation on Commercial Communication and Commercial Electronic Messages published in the Official Gazette dated 4 January 2020 and numbered 30998. Amendments regarding the use of the İYS will be effective as of 16 January 2021.

In the Regulation, İYS has been defined as the system that enables obtaining consent for commercial electronic messages, exercising the right to opt-out and managing the complaint processes.

İYS is a national database where;

  • Service providers store and manage different types of authorization for electronic communications, such as calls, messages, and emails;
  • Recipients (i) view their consents, (ii) submit complaints regarding unauthorized submissions, and (iii) make notifications of consent and opt-out;
  • Public authorities can view the complaints and the status of the consents subject to the complaint.

What has changed with the establishment of the İYS?

With the establishment of the İYS, all commercial electronic message consents can be stored and managed on a single platform.

With the amendments made within the scope of the Regulation, it has become mandatory for real and legal persons who wish to send commercial electronic messages to register with the İYS until 1 December 2020[1].

In the same regard, as of 16 January 2021,commercial electronic messages will not be sent to recipients whose consents are not present on the İYS. Consents obtained but not registered by 1 December 2020 with the İYS shall be deemed as invalid.

The Ministry of Commerce is authorized to postpone the said deadline for six months by taking into account the nature of the service providers and the size of the commercial electronic message consents.

[1] Initially the deadline was 31 August 2020; then it has been postponed to 1 December 2020.

Consent Process:

For the recipients who are tradesmen or craftsman, the electronic contact addresses of the persons will be registered with the İYS by the service provider and it will be checked whether the recipient group to whom the electronic commercial messages shall be sent exercised their right to opt-out on the İYS, before sending any commercial electronic messages.

With the establishment of the İYS, service providers now can obtain consents via İYS. The İYS will provide services for obtaining consent to service providers over various communication channels as value added services.

Within this scope, recipient consents can be obtained:

  • Physically with signatures
  • Electronically
  • Via the İYS

On the other hand, the recipients may access and change their consent preferences through İYS’s website or e-Government system. Citizens’ access to İYS will be available as soon as possible .

Consents obtained by any method other than the İYS will be uploaded to the İYS within 3 business days. Otherwise, obtained consents will be considered as invalid since they are not registered with the İYS.

Service providers should transfer all consents duly obtained to the system (i) manually (ii) in bulk through .cvs files or (iii) by the mean of technical integration through İYS API. Only approved electronic contact addresses must be uploaded to the system by service providers. The electronic communication address, which is not registered with the İYS, would be considered as a rejection to receive electronic communication.

Service providers will transfer the consents to the system based on “declaration”, and documents that certify consent are not required to be uploaded to the system. The obligation to prove all past consents uploaded to the İYS falls on the service provider.

The consent uploaded to the İYS must contain the following information:

  • Contact address

The opportunity for opt-out shall be included in every commercial electronic message sent or otherwise it may be subject to complaints.

Service providers will be able to design their own opt-out procedures and process those into the İYS or they can receive these opt-out services from the İYS as a value-added service.

Recipients will be able to start using the İYS directly.

Only (i) Service Providers themselves, (ii) public institutions if necessary and intermediary service providers acting on behalf of Service provider will be authorized to access the data uploaded to the İYS by Service Providers. İYS personnel and other service providers will not be authorized to access the data uploaded by Service Providers.

  • a message will be sent to the recipients stating that their consents have been uploaded to the İYS by the system and that these consents will be considered valid and that the opportunity for rejection can be used through the İYS if they do not check until 16 January 2021.
  • As of 1 December 2020, the deadline for the transfer of consents, the İYS will be available for recipients and the public.

  • Notifies the İYS if recipients close the subscription line;

What are the consequences of violation of İYS Regulations?
