TLS Reporting – Find Email Delivery Issues with Pinpoint Accuracy with SMTP TLS Reporting
Leverage TLS reporting to maximize visibility on your domain and boost deliverability
Leverage TLS reporting to maximize visibility on your domain and boost deliverability
TLS Reporting (TLS-RPT) is a standard for reporting email delivery issues that occur when an email isn’t encrypted with TLS. It supports the MTA-STS protocol which is used to guarantee that any email sent to your domain gets TLS encrypted.
TLS encryption ensures that every email sent to you gets delivered securely. However, an attacker might attempt an SMTP downgrade, a type of attack where the email gets sent to you without being encrypted, allowing them to read or tamper with the contents. MTA-STS combats this by making it necessary for all emails to be encrypted before being sent to you. If an attacker tries to perform an SMTP downgrade, the email will not be sent at all.
TLS-RPT makes it possible for you, the domain owner, to receive reports on every email that doesn’t get encrypted and fails to be sent to you. You can then identify the source of the problem and fix your delivery issues.
TLS reporting (TLS-RPT) is used to support the MTA-STS protocol, which ensures emails are encrypted before being delivered. Normally, your email server or Mail Transfer Agent (MTA) negotiates with the receiving server to see if it supports the STARTTLS command. If it does, the email gets encrypted with TLS and gets delivered to the receiving MTA.
An attacker might attempt an SMTP downgrade attack at this point, which involves blocking the negotiation between the sending and receiving MTAs. The sending server thinks the receiver doesn’t support the STARTTLS command and sends the email without TLS encryption, allowing the attacker to view or tamper with the email’s contents.
When you implement MTA-STS in your domain, it makes it mandatory for your sending server to always encrypt messages before sending them. If an attacker attempts an SMTP downgrade attack, the email will simply not be sent. This ensures TLS encryption on all your emails without fail.
TLS reporting (TLS-RPT) is a protocol that will notify you, the domain owner when emails sent through your domain face issues with delivery. If an email fails to be sent due to an SMTP downgrade or some other issue, you will receive a report in a JSON file format containing the details of the email that failed. This report does not contain the contents of the email.

This Privacy Information explains how we use your personal data: how it is collected, how it is held, and how it is processed. It also explains your rights under the law relating to your personal data.
2. What is Personal Data?
Personal data is defined by the General Data Protection Regulation (EU Regulation 2016/679) (the “GDPR”) as ‘any information relating to an identifiable person who can be directly or indirectly identified in particular by reference to an identifier’.
Personal data is, in simpler terms, any information about you that enables you to be identified. Personal data covers obvious information such as your name and contact details, but it also covers less obvious information such as identification numbers, electronic location data, and other online identifiers.
The personal data that we use is set out in Section 4, below.
3. What are my rights?
Under the GDPR, if you are a resident in the EEA, you have the following rights, which we will always work to uphold:
The right to be informed about our collection and use of your personal data. This Privacy Notice should tell you everything you need to know, but you can always contact us to find out more or to ask any questions using the details in Section 10.

Comments and opinions that you express when you contact us via email, phone or chat.
5. How is my personal data used?
Under the GDPR, we must always have a lawful basis for using personal data. This may be because the data is necessary for our performance of a contract with you, because you have consented to our use of your personal data, or because it is in our legitimate business interests to use it. Your personal data will be used for the following purposes:
Providing and managing your account (legal basis: contractual).

We will always work to fully protect your rights and comply with our obligations under the GDPR and the Privacy and Electronic Communications (EC Directive) Regulations 2003, and you will always have the opportunity to opt-out.
6. For how long will you keep my personal data?
We will not keep your personal data for any longer than is necessary in light of the reason(s) for which it was first collected. Your personal data will therefore be kept for the following periods (or, where there is no fixed period, the following factors will be used to determine how long it is kept):
We will use and store your personal data for as long as it is necessary to provide our service to you and for the purpose of satisfying any legal, accounting or reporting requirements. Thereafter we will only keep data in anonymised form so that it can no longer be associated with you to help improve our products and services;
if you are not a customer and we have your personal data for the purpose of communicating with you we will use it and store it until either you let us know that you no longer want to receive communications from us or for a period of up to 24 months;
7. How and Where do you store my personal data?
We may store or transfer some or all of your personal data in countries that are not part of the European Economic Area (the “EEA” consists of all EU member states, plus Norway, Iceland, and Liechtenstein). These are known as “third countries” and may not have data protection laws that are as strong as those in the UK and/or the EEA. This means that we will take additional steps in order to ensure that your personal data is treated just as safely and securely as it would be within the UK and under the GDPR including:
Having a GDPR-compatible Data Processing Addendum with sub-processors in third countries;
Making sure that such sub-processors have adequate security procedures in place.
The security of your personal data is essential to us, and to protect your data, we take a number of important measures, including the following:
· Encrypting your data while it is in transit;
· Where possible, encrypting your data when it is stored;
· Yearly independent reviews of our security processes and procedures via our ISO27001 certification.
8. Do you share my personal data?
We may sometimes contract with the following third parties to supply products and services to you on our behalf. These may include payment processing, delivery, and marketing. In some cases, those third parties may require access to some or all of your personal data that we hold. You can check the list of sub processors here.
If any of your personal data is required by a third party, as described above, we will take steps to ensure that your personal data is handled safely, securely, and in accordance with your rights, our obligations, and the third party’s obligations under the law.
We may sometimes contract with third parties (as described above) that are located outside of the European Economic Area (the “EEA” consists of all EU member states, plus Norway, Iceland, and Liechtenstein). If any personal data is transferred to a third party outside of the EEA, we will take suitable steps in order to ensure that your personal data is treated just as safely and securely as it would be under the GDPR, as explained above in Section 7.
In some limited circumstances, we may be legally required to share certain personal data, which might include yours, if we are involved in legal proceedings or complying with legal obligations, a court order, or the instructions of a government authority.
9. How can I access my personal data?
If you want to know what personal data we have about you, you can ask us for details of that personal data and for a copy of it (where any such personal data is held). This is known as a “subject access request”.
All subject access requests should be made in writing and sent to the email or postal addresses shown in Section 10.
There is not normally any charge for a subject access request. If your request is ‘manifestly unfounded or excessive’ (for example, if you make repetitive requests) a fee may be charged to cover our administrative costs in responding.
We will respond to your subject access request within 21 days and, in any case, not more than one month of receiving it. Normally, we aim to provide a complete response, including a copy of your personal data within that time. In some cases, however, particularly if your request is more complex, more time may be required up to a maximum of three months from the date we receive your request. You will be kept fully informed of our progress.
