Sendmarc simplifies TLS-RPT implementation, making encrypted email delivery reliable and transparent. What is TLS-RPT, though? Transport Layer Security Reporting (TLS-RPT) gives your organization insights into failed email encryption attempts, helping you detect issues, fix misconfigurations, and safeguard communications.

Email is vital to business communication and a frequent target for cybercriminals. Without secure transmission, emails containing sensitive information can be intercepted during transit.
Real-world example:
Consider that financial or legal documents are emailed to a client. If the email isn’t encrypted, it could be intercepted during transmission, leading to:
What is TLS-RPT’s role? TLS encrypts data sent between email servers, ensuring that messages remain private while in transit. When both the sender and recipient servers support TLS, the email content is protected from unauthorized access.
But TLS encryption depends on its configuration. If misconfigured or if a threat actor attempts to downgrade the connection to bypass encryption, emails can be accessed. TLS-RPT detects these issues, allowing for timely correction.
Businesses that don’t implement TLS-RPT risk the following:
TLS-RPT works alongside other email security protocols to give domain owners visibility into encryption issues during email transmission. By identifying failed security connections, TLS-RPT helps companies maintain email integrity and compliance.
Key terms to know:
A standard TLS-RPT report includes the following information:
These reports are commonly delivered in JSON format.
Implementing TLS-RPT provides advantages to organizations of all sizes. Businesses that adopt TLS-RPT can:
TLS-RPT alerts companies when there are problems with encrypted email delivery. This enables fast identification of misconfigurations or potential cyberattacks, reducing vulnerability.
By identifying encryption failures, TLS-RPT checks that all outgoing emails are transmitted securely. This lowers the risk of data breaches and interception by cybercriminals.
Industries such as finance, healthcare, and legal services are subject to strict regulations on data protection. TLS-RPT helps meet compliance requirements by providing documentation of encryption issues.
Customers expect their information to be securely handled. Using TLS-RPT shows a commitment to email security, enhancing your organization’s credibility and reputation.
TLS-RPT provides security and IT teams with the data needed to identify and resolve issues before they escalate.

TLS stands for Transport Layer Security, which is a standard that encrypts data sent over the internet. TLS is commonly used to secure email communications and protect messages from interception during transmission.
To set up TLS-RPT, follow these three main steps:
Host | Type | Value |
---|---|---|
_smtp._tls.yourdomain.com | TXT | v=TLSRPTv1; rua=mailto:[email protected] |
A TLS report is a document, typically JSON formatted, that’s sent by external email servers to your organization. It outlines encryption-related issues seen during email delivery.
TLS-RPT works with DMARC and MTA-STS:
If TLS-RPT isn’t implemented, your business will lack visibility into whether outgoing emails are being securely delivered using TLS encryption. This can result in undetected encryption failures, increased risk of data breaches, and damage to your company’s reputation.
