MailerLite will restrict its Sub-Processors’ access to only what is necessary to maintain the Services or to provide the Services to Customers. Subject to this Section 7, MailerLite reserves the right to engage and substitute Sub-Processors as it deems appropriate, but shall: (a) remain responsible to the Customer for the provision of the Services and (b) be liable for the actions and omissions of its Sub-Processors undertaken in connection with MailerLite’s performance of this DPA to the same extent MailerLite would be liable if performing the Services directly.

7.2. Upon the Customer’s request by email to, MailerLite will provide the Customer with a list of then-current third-party Sub-Processors and the nature of the services they provide. The Customer can find an up-to-date list of Sub-Processors in Annex 3 of this DPA.

(a) MailerLite will cancel its plans to use the Sub-Processor with regard to Customer Data or will offer an alternative to provide the Services without such Sub-Processor;

(c) MailerLite may cease to provide, or the Customer may agree not to use (temporarily or permanently), the particular aspect of the Services that would involve the use of such Sub-Processor with regard to Personal Data, subject to a mutual agreement of the Parties to adjust the remuneration for the Services considering their reduced scope.

7.3. All Objection Notices under Section 7.2 must be submitted by email to MailerLite at If none of the options outlined in Clause (a), (b) or (c) of Section 7.2 are reasonably available and Customer’s objection has not been resolved to the Parties’ mutual satisfaction within 30 days of MailerLite’s receipt of the Objection Notice, either Party may terminate the affected Services and MailerLite will refund to the Customer a pro rata share of any unused amounts prepaid by the Customer. The refund will be calculated in proportion to what Services have been provided until the time the Customer has informed MailerLite on terminating the Services. MailerLite does not provide any refunds if the Objection Notice does not have reasonable legal grounds.

8. Data Subject Rights

8.1. If MailerLite receives a request from a Data Subject in relation to the Customer Data then, to the extent legally permissible, MailerLite will advise the Data Subject to submit their request to the Customer and the Customer will be responsible for responding to any such request including, where necessary, by using the functionality of the Services. The Customer hereby agrees that MailerLite may confirm to a Data Subject that his or her requests relate to the Customer. To the extent the Customer is unable through its use of the Services to address a particular Data Subject request, MailerLite will, upon the Customer’s request and taking into account the nature of Customer Data Processed, provide reasonable assistance in addressing the Data Subject request (provided MailerLite is legally permitted to do so and that the Data Subject request was made in accordance with EU Data Protection Law). To the extent permitted by applicable law, the Customer shall be responsible for any costs arising from MailerLite’s provision of such assistance.

9. Deletion Upon Expiration

9.1. Upon termination of the TOU and/or DPA, MailerLite will initiate a process upon the Customer’s written request that deletes Customer Data in its possession or control. This requirement shall not apply to the extent MailerLite is required by the applicable law to retain some or all of the Customer Data, or to Customer Data it has archived on back-up systems, which Customer Data MailerLite shall securely isolate and protect from any further processing, except to the extent required by applicable law.

10. Customer Data Breach Management

10.1. MailerLite will notify the Customer without undue delay, and in any event within 48 hours, after becoming aware of a Personal Data Breach with respect to Customer Data transmitted, stored or otherwise Processed by MailerLite or its Sub-Processors (a “Customer Data Breach”). Such notice may be provided (1) by posting a notice in the Services; (2) by sending an email to the email address from which the account of Authorized User was created; and/or (3) pursuant to the notice provisions of the TOU. The Customer shall ensure that its contact information is current and accurate at all times during the terms of this DPA. MailerLite will promptly take all actions relating to its Security Measures (and those of its Sub-Processors) that it deems necessary and advisable to identify and remediate the cause of a Customer Data Breach. In addition, MailerLite will promptly provide the Customer with: (i) reasonable cooperation and assistance with regard to the Customer Data Breach, (ii) reasonable information in MailerLite’s possession concerning the Customer Data Breach insofar as it affects the Customer, including remediation efforts and any notification to Supervisory Authorities and, (iii) to the extent known: (a) the possible cause of the Customer Data Breach; (b) the categories of Customer Data involved; and (c) the possible consequences to Data Subjects. MailerLites’s notification of or response to a Customer Data Breach under this Section will not constitute an acknowledgment of fault or liability with respect to the Customer Data Breach, and the obligations herein shall not apply to Personal Data Breaches that are caused by the Customer, Authorized Users or providers of Customer components (such as systems, platforms, services, software, devices, etc.). If the Customer decides to notify a Supervisory Authority, Data Subjects or the public of a Customer Data Breach, the Customer will provide MailerLite with advance copies of the proposed notices and, subject to applicable law (including any mandated deadlines under EU Data Protection Law), allow MailerLite an opportunity to provide any clarifications or corrections to those notices.

In such case:

(a) The Customer shall: (i) provide MailerLite at least 30 days’ prior written notice of any proposed audit; (ii) undertake an audit no more than once in any 12-month period, except where required by a competent Supervisory Authority or where an audit is required due to a Customer Data Breach; and (iii) conduct any audit in a manner designed to minimize disruption of MailerLite’s normal business operations. To that end and before the commencement of any such audit, the Customer and MailerLite shall mutually agree upon any reimbursement of expenses for which the Customer shall be responsible as well as audit’s participants, schedule and scope, which shall in no event permit the Customer or its third-party auditor to access the Services’ hosting sites, underlying systems or infrastructure.

(b) Representatives of the Customer performing an audit shall protect the confidentiality of all information obtained through such audits in accordance with the TOU, may be required to execute an enhanced mutually agreeable nondisclosure agreement and shall abide by MailerLite’s security policies while on MailerLite’s premises.

13.2. Sub-Processors used by MailerLite to Process any Customer Data protected by Data Protection Laws and/or that originates from the EEA, in a country that has not been designated by the European Commission or Swiss Federal Data Protection Authority (as applicable) will provide an adequate level of protection for Personal Data and have SCC integrated in their Data Processing Agreements.

13.3.

16.4. This DPA shall be governed by and construed in accordance with governing law and jurisdiction provisions in the TOU, unless required otherwise by applicable Data Protection Laws.

16.5. The Customer ensures that the decision to agree with the terms and conditions of this DPA was made lawfully by the Customer, in case the Customer is a natural person, or, by the Customer’s director, authorized representative or other person having signatory powers, in case the Customer is a legal person.
