Data controller

For the purpose of data protection legislation including the General Data Protection Regulation (‘GDPR’), the data controller of your personal data is:

MailNinja Limited (registered at Companies House with company number 08740980 and trading as emailninja).

Registered Address: 128 City Road, London, England, EC1V 2NX

Who is this policy addressed to?

When we refer in this policy to ‘you’, we are referring to a customer of our services, or a person visiting our website. We are not referring to a person receiving an email sent by a customer using our service, or a person on a mailing list maintained by one of our customers. We refer to those people in this policy as ‘Contacts’. We do not have any relationship with Contacts, and process information relating to them solely for the purposes of providing our service to our customers.

When we refer to a ‘contact list’ in this policy, we are referring to details of Contacts (including their email addresses) processed by us on your behalf to provide you with our emailninja service.

If you are a Contact and wish to cease receiving emails from one of our customers, please unsubscribe directly using the unsubscribe link in the customer’s email, or contact the customer directly.

If a Contact makes a direct request to be removed from the contact list of one of our customers, we may do so on behalf of our customer, while providing notice to the customer of the Contact’s request. Our customer is the data controller in respect of Contacts’ personal data, and Contacts should consult our customer’s own Privacy Policy for details on the customer’s data protection practices. We will never use the Contact email addresses to send our own informational and promotional content. We may refer to Contact’s personal data when generating usage reports and analysis as data processor for our data controller customers. This may involve analysis on the events (such as bounces, unsubscribes, clicks, and opens) arising from emails sent to Contacts using our service.

The majority of these cookies are required to provide our service, ensuring you remain signed in to MailNinja and that we can personalise the service offered. We may also use cookies and other similar tracking technologies, such as web beacons, for advertising and targeting purposes. For more information about cookies, visit our Cookies Policy

Where we store your personal data

  • Account details and IP addresses that we collect from you are stored on our servers located in the European Union. All the personal data we collect from you may be processed by our staff. Such staff may be engaged in, among other things, the fulfilment of your services, and the provision of support services. We will take all steps reasonably necessary to ensure that your data is treated securely and in accordance with this privacy policy. Please contact us if you would like more details on the appropriate safeguards we employ to require that these providers process your data with due respect for its privacy.


  • All information you provide to us is stored on our secure servers. Any payment transactions will be carried out by Stripe over encrypted connections using SSL technology (see the ‘Payment Information’ section above). Where we have given you (or where you have chosen) a password or API key which enables you to access certain parts of our site, or you have invited team members to access parts of our site, you are responsible for keeping this password or API key confidential.
  • We take security very seriously, and ‘privacy by design’ is baked into our engineering and product development principles but, as with any online service, despite our use of leading security tools and techniques, the personal data we hold about you can never be 100% immune from unauthorised access.

Disclosure of your information

We may disclose your personal information to any company under the same ownership as us.

We may disclose your personal information to selected third parties, including:

  • in the event that we sell or buy any business or assets, the prospective seller or buyer of such business or asset;
  • if MailNinja or substantially all of its assets are acquired by a third party, to the relevant third party;
  • business parties and subcontractors for the purposes of providing MailNinja services;
  • when an email is sent, Elastic Email will see the ‘from’ name and address, the subject, the body of the email, and the destination email addresses. When an email recipient opens an email you have sent or clicks a link in the email, Elastic Email will see the IP address of the recipient (from which may be inferred a notional latitude and longitude associated with that IP address);
  • analytics providers that assist us in the improvement and optimisation of our website; and
  • law enforcement agencies or regulatory bodies; or other third parties for fraud detection and prevention. We will only do this is if we are legally required to do so;

We may also disclose your personal information to third parties if we are under a duty to disclose or share your personal data in order to comply with any legal obligation, or in order to enforce or apply our Terms of Service and other agreements, or to protect the rights, property, or safety of MailNinja, our customers, or others. This includes exchanging information with other companies and organisations for the purposes of fraud detection and protection and credit risk reduction.

Third party integrations

  • You can additionally integrate your MailNinja account with third party apps, websites or other services with whom you have your own account independent of MailNinja. If you do decide to connect your account with that third party to MailNinja, the third party you integrate will as a result receive your contact lists, information about your use of our services, and access to any other personal data you make available to them. All third parties you integrate in this way are your own data processors – they are not sub-contractors or sub-processors of MailNinja. Information collected by these third parties is subject to their own terms and privacy policies. We use Zapier to allow you to integrate third party applications.

Retention of your personal information

  • The periods for which we keep your information depend on why your information was collected and what we use it for. We will not keep your personal information for longer than necessary for our business purposes or for legal requirements.
  • If you cancel your subscription and the current period has ended, we will keep your account live for up to 60 days, giving you the opportunity to renew your subscription prior to closing your account and deleting your data. During this time, we may attempt to send warning emails to your account email address so that you have an opportunity to restart your plan and back up any data you may need. We may also contact you about our services during this time.
  • After the 60-day renewal window, we may keep a backup copy of your data on our servers for reporting, campaign archiving or personalisation (live merge tag) purposes. We may also keep limited information for up to 6 years for compliance and accounting purposes and to enforce or defend any legal claims in respect of our terms of service.

Legal basis for processing

We are required to state the legal basis on which we undertake processing of your personal information. We will only use your information where:

  • we have your consent to do so; or
  • we need to process the personal information to perform services for you under our terms of service.
  • we have a legitimate interest in engaging in the provision of our MailNinja service and in offering products and services of value to you. Please contact us if you would like to learn more about our assessment of our legitimate interests in processing data.
  • we are processing the data to meet a legal requirement.

Any consent you provide may be withdrawn at any time by emailing us.

Your rights

You have the right to request access to personal data that we may process about you.

You have the right to require us to correct any inaccuracies in your data, free of charge. If you wish to exercise this right, you should:

  • put your request in an email to us;
  • provide us with enough information to identify you (e.g. username or email address); and
  • specify the information that is incorrect and what it should be replaced with.

You can access, correct, update or request deletion of your personal information at any time, either through your online account or by contacting us.

Deletion of data will be carried out on the understanding that removal of some information (e.g. email address) during an active membership term may negatively affect your ability to use the MailNinja service.

Invoices are sent directly from Stripe and are stored on their servers. We cannot delete invoices, as these are kept for tax purposes.

You can request that we restrict the processing of your personal information, object to the processing of your information or request portability of your personal information. For these requests please contact us. We will comply with your request where your rights have been exercised in accordance with applicable laws.

You have the right to obtain and reuse your personal data in a structured, commonly used and machine-readable format in certain circumstances. In addition, where certain conditions apply, you have the right to have such information transferred directly to a third party.

If we have collected and processed your personal information with your consent, then you can withdraw that consent at any time. To be clear, we may still continue to process your data if we have a different legal basis for doing so (for example, if we are required by law to do so, or we need to do so for the purposes of fulfilling our obligations to you under our terms of service).

You also have the right to ask us to stop processing your personal data for direct marketing purposes. You can do this through your MailNinja dashboard or via email. If you wish to exercise this right via email, you should:

  • put your request in writing (an email with a header that says ‘Unsubscribe’ is acceptable);
  • provide us with enough information to identify you (e.g. email address); and
  • if your objection is not to direct marketing in general, but to direct marketing by a particular channel (e.g. email or telephone), please specify the channel you are objecting to.

You have the right to make a complaint to the Information Commissioner’s Office (ICO) if you are unhappy with how we have handled your personal data or believe our processing of your personal data does not comply with data protection law.

Please note that the right of access and the right to erasure do not constitute absolute rights and the interests of other individuals may restrict your right of access or erase in accordance with local laws.

Important notice regarding your rights: You will not have to pay a fee to access your personal data (or to exercise any of the other rights). However, we may charge a reasonable fee if your request is clearly unfounded, repetitive or excessive. Alternatively, we may refuse to comply with your request in these circumstances. We may need to request specific information from you to help us confirm your identity and ensure your right to access your personal data (or to exercise any of your other rights). This is a security measure to ensure that personal data is not disclosed to any person who has no right to receive it. We may also contact you to ask you for further information in relation to your request to speed up our response. We try to respond to all legitimate requests within one month. Occasionally it may take us longer than a month if your request is particularly complex or you have made a number of requests. In this case, we will notify you and keep you updated. 

International transfers 

Some of our external third parties are based or send personal data outside the European Economic Area (EEA) so their processing of your personal data will involve a transfer of data outside the EEA.

Whenever we transfer your personal data out of the EEA, we ensure a similar degree of protection is afforded to it by ensuring at least one of the following safeguards is implemented:

  1. Where we use certain service providers, we may use specific contracts approved by the European Commission which give personal data the same protection it has in Europe. For further details, see European Commission: Model contracts for the transfer of personal data to third countries.
  2. Where we use providers based in the US, we may transfer data to them if they are part of the Privacy Shield which requires them to provide similar protection to personal data shared between Europe and the US. For further details, see European Commission: EU-US Privacy Shield.

Please contact us if you want further information on the specific mechanism used by us when transferring your personal data out of the EEA.
