What is a TLS-RPT record checker?
A Transport Layer Security Reporting (TLS-RPT) record checker verifies the presence and correctness of your organization’s record, which is critical for maintaining secure and reliable email communications.
Key features of a TLS-RPT checker
- Check the DNS TXT record at
_smtp._tls.yourdomain.com - Verify the format and accuracy of the domain’s record
- Confirm the version and reporting address are correct

What is TLS-RPT?
TLS-RPT is a reporting protocol that allows domain owners to receive daily reports on email delivery issues related to encryption. These reports help identify and troubleshoot problems with TLS.
Why does TLS-RPT matter?
Without TLS-RPT, domain owners might be unaware of TLS misconfigurations that leave messages vulnerable to interception, tampering, or Man-in-the-Middle (MitM) attacks. By receiving detailed reports on TLS failures, companies can identify and resolve problems quickly, ensuring that email communications remain secure and reliable.
Why your organization should use a TLS-RPT record checker
Businesses that value secure and reliable email communication benefit from implementing and validating TLS-RPT. The protocol helps:
- Detect encryption failures: Identify if messages aren’t delivered securely due to TLS issues
- Prevent data breaches: Address vulnerabilities that could expose sensitive email content to cybercriminals
- Monitor policy compliance: Validate compliance with email security standards
- Improve deliverability: Resolve issues that might prevent legitimate emails from reaching recipients
Typical use cases
- Troubleshooting failed email deliveries
- Verifying new or updated DNS records
- Monitoring compliance with email security policies
Check if your company’s record is properly configured.
How to verify with a TLS-RPT record checker
Use Sendmarc’s record checker tool to confirm that your organization’s TLS-RPT TXT record is present, correctly formatted, and functional.Step-by-step guide
1. Enter the domain
Input the domain into the record checker2. TLS-RPT check
The checker analyzes the DNS for the TXT record3. Validation
The tool checks the record for correct syntax, required fields, and valid reporting addresses4. Review results

Missing or incorrect record? Use a TLS-RPT record checker
If your business’s record is missing or incorrectly configured, it won’t receive crucial reports about encryption failures. This might leave your company vulnerable to undetected security issues.

TLS-RPT record checker FAQs
What is a TLS-RPT record?
A Transport Layer Security Reporting (TLS-RPT) record is a DNS TXT entry that specifies where to send reports about email encryption failures for a domain. A TLS-RPT record allows domain owners to monitor and address issues related to encrypted email delivery.
What does a valid TLS-RPT record look like?
| Host | Type | Value |
|---|---|---|
| _smtp._tls.yourdomain.com | TXT | v=TLSRPTv1; rua=mailto:[email protected] |
| Host | Type | Value |
|---|---|---|
| _smtp._tls.yourdomain.com | TXT | v=TLSRPTv1; rua=mailto:[email protected],https://yourdomain.com/tlsrpt |
What happens if my TLS-RPT record is incorrect?
If a TLS-RPT record is incorrect or missing, the domain owner won’t receive reports about TLS failures. Without these reports, encryption issues might go undetected, potentially exposing email to interception or modification.
How do I fix a TLS-RPT misconfiguration?
rua address is valid and actively monitored. After making updates, re-check the configuration to confirm compliance and functionality.
How does TLS-RPT affect my email deliverability?
TLS-RPT affects email deliverability by enabling domain owners to detect and resolve encryption-related issues. By identifying and correcting these problems, TLS-RPT improves both the security and successful delivery of emails.
Can I have multiple TLS-RPT records?
_smtp._tls.yourdomain.com. To specify more than one reporting address, separate each rua value with a comma.
Do I need TLS-RPT if I already have MTA-STS?
Yes, TLS-RPT is still necessary even if Mail Transfer Agent Strict Transport Security (MTA-STS) is implemented. While MTA-STS enforces the use of TLS for email transmission, TLS-RPT provides reporting and visibility into encryption failures. Using both protocols together ensures both enforcement and monitoring, strengthening overall email security.
