Summary
Privacy errors when clicking email links from Gmail in Chrome, often displaying messages like "Your connection is not private," are multi-faceted. They primarily stem from issues with SSL/TLS certificates on the linked website or click-tracking domain, but can also be caused by various client-side, network, or software-related problems. Diagnosing these errors requires checking both the website's security setup and the user's local browsing environment, as well as understanding how different software interacts with secure connections.
Key findings
- SSL Certificate Problems: A primary cause involves invalid, expired, mismatched, or untrusted SSL/TLS certificates on the landing page or dedicated click-tracking domains. Chrome's strict security policies, including distrusting certain Certificate Authorities or enforcing HTTPS, contribute to these warnings.
- Client-Side Configuration: Incorrect system date and time, outdated Chrome browsers, and corrupted browser data such as cache and cookies can lead to certificate validation failures, even for valid sites.
- Software Interference: Antivirus software, especially those with HTTPS scanning features, as well as conflicting browser extensions, VPNs, or proxy servers, can intercept or disrupt secure connections, triggering privacy errors.
- Network and System Issues: Beyond local software, underlying network problems like incorrect DNS settings, or even system-wide issues such as malware, can interfere with Chrome's ability to establish a secure connection, causing valid links to appear insecure.
Key considerations
- Verify SSL Certificate Validity: For email marketers, ensure all linked domains, including custom tracking domains, have valid, up-to-date, and correctly configured SSL/TLS certificates from trusted Certificate Authorities. This prevents errors caused by expired or mismatched certificates.
- Troubleshoot Client-Side Settings: Advise users to check their computer's date and time, clear Chrome's cache and cookies, disable suspicious browser extensions, and update their browser to the latest version. These steps often resolve issues stemming from local misconfigurations.
- Check for Software Conflicts: Investigate whether antivirus software, VPNs, or proxy settings are interfering with secure connections. Temporarily disabling these tools can help diagnose if they are the root cause of privacy warnings.
- Inspect and Diagnose Errors: Understand that specific error messages, like 'NET::ERR_CERT_DATE_INVALID' or name mismatch errors, provide vital clues. Inspecting the certificate details in Chrome can reveal the exact nature of the problem, such as who owns the certificate or if HSTS is forcing HTTPS incorrectly.
- Consider System Integrity: For persistent or widespread issues, recommend scanning the computer for malware, which can interfere with secure connections. As a last resort, a full reset or reinstallation of Chrome might be necessary to address severely corrupted browser data.
What email marketers say
9 marketer opinions
Privacy errors encountered when clicking email links from Gmail in Chrome, commonly presenting as 'Your connection is not private' warnings, arise from a complex interplay of factors. These range from fundamental issues with the SSL/TLS certificates on the target website or email click-tracking domain, to client-side problems like incorrect system time, outdated browsers, and corrupted data. Network configurations and interfering software such as VPNs or antivirus programs can also play a significant role, making a systematic troubleshooting approach essential.
Key opinions
- SSL Certificate Mismatches and Invalidations: A primary cause of privacy errors involves invalid, expired, or mismatched SSL/TLS certificates on the linked website or custom click-tracking domain. These often manifest as name mismatch errors, occurring when dedicated click tracking or HSTS forces SSL on a URL that doesn't match the certificate.
- System Clock and Browser Integrity: An incorrect system date and time on the user's computer is a common trigger for 'NET::ERR_CERT_DATE_INVALID' errors, as Chrome relies on the system clock to validate certificate expiry. Outdated Chrome versions and severely corrupted browser data can also lead to certificate validation failures.
- Network and Software Conflicts: Various software and network configurations can interfere with secure connections. This includes antivirus software with HTTPS scanning, conflicting browser extensions, problematic VPNs (due to server issues or SSL/TLS inspection), incorrect DNS settings, and the use of proxy servers. Malware on the computer can also cause persistent errors.
Key considerations
- Rigorous SSL Certificate Checks: Email marketers should meticulously verify SSL/TLS certificates for all linked domains, including custom click tracking. Ensure these certificates are valid, current, issued by trusted authorities, and correctly configured to prevent common mismatch and expiration errors.
- System-Level Troubleshooting for Users: Guide users to first correct their computer's date and time, as this simple fix often resolves 'NET::ERR_CERT_DATE_INVALID' errors. Additionally, recommend regularly updating Chrome and addressing corrupted browser data through clearing cache or, if necessary, reinstalling the browser.
- Diagnosing Network and Software Interference: Counsel users to investigate their network settings for incorrect DNS or proxy configurations. Also, test for conflicts with VPNs, antivirus software-especially those with HTTPS scanning-or browser extensions, which can often intercept or block secure connections.
- Advanced Problem Solving: For persistent privacy errors, suggest scanning the computer for malware, which can undermine secure browsing. Leveraging browser developer tools to inspect certificate details and network activity can also provide deeper insights into the specific nature of the problem, such as certificate ownership or HSTS issues.
Marketer view
Marketer from Email Geeks suggests that privacy errors with email links in Chrome are likely caused by a security certificate issue, such as the certificate being recently expired or Chrome not trusting its root. Mickey C. clarifies that the problem lies with the invalid security certificate, not the domain itself.

Marketer view
Marketer from Email Geeks explains that privacy errors, specifically name mismatch errors, frequently occur with certificate mismatches when clicking email links. This can happen if dedicated click tracking from an ESP like SendGrid is used, or if a 3rd party add-on or HSTS forces SSL (HTTPS) on the URL, causing the certificate to not match the domain. Francis Baker suggests troubleshooting by trying to remove the 'S' from HTTPS, inspecting who owns the certificate, and considering a reverse proxy setup to handle SSL traffic as a solution.

What the experts say
1 expert opinions
When users encounter privacy errors, such as "Your connection is not private," after clicking email links from Gmail in Chrome, a significant underlying cause can be Chrome's explicit distrust of the SSL certificate on the destination landing page or, notably, the link tracking domain. This type of error is particularly evident and frustrating when it uniformly affects all links in an email, indicating a systemic issue with the certificate securing the tracking or destination domain.
Key opinions
- Chrome SSL Distrust: Privacy errors often stem from Chrome not trusting the SSL certificate associated with either the landing page URL or the email's link tracking domain. This distrust leads to security warnings, especially when the issue is pervasive and affects all clickable links within a specific email campaign.
Key considerations
- Ensure Tracking Domain SSL Trust: Email marketers must ensure that their click-tracking domains, in addition to landing pages, have valid, trusted, and correctly configured SSL certificates. A lack of trust from browsers like Chrome in these certificates can lead to widespread privacy errors, preventing subscribers from accessing content.
Expert view
Expert from Email Geeks explains that privacy errors encountered when clicking email links in Chrome could be due to Chrome not trusting the SSL certificate on the landing page, especially if the issue affects all links and points to the link tracking domain.

What the documentation says
3 technical articles
Privacy errors, such as 'Your connection is not private,' when accessing email links from Gmail in Chrome frequently arise from a combination of factors. These include local system settings, browser integrity issues, interference from security software or extensions, and Chrome's rigorous security policies regarding SSL/TLS certificates, particularly its potential distrust of specific Certificate Authorities.
Key findings
- Client-Side Configuration: Common local issues such as an incorrect system date or time, along with corrupted browser data like cache and cookies, or conflicting browser extensions, can prevent Chrome from establishing a secure connection to linked websites.
- Security Software Interference: Antivirus programs, particularly those with HTTPS scanning capabilities (e.g., Avast's Web Shield), and firewalls can intercept secure connections. If their self-signed certificates are not fully trusted by Chrome, this interception leads to privacy warnings.
- Chrome's Certificate Distrust: Chrome's strict and evolving policies on SSL/TLS certificates mean it may explicitly distrust certificates from certain Certificate Authorities due to past compliance issues. This can trigger 'Your connection is not private' errors for websites using those certificates, regardless of the site's legitimacy.
Key considerations
- User-Level Troubleshooting: Instruct users to verify their system's date and time, clear Chrome's browsing data, including cache and cookies, and temporarily disable browser extensions. These steps can diagnose and resolve common client-side privacy errors.
- Managing Security Software: Advise users to investigate their antivirus software and firewall settings. Specifically, if an antivirus has an HTTPS scanning feature, temporarily disabling it or adjusting its trust settings can help troubleshoot 'connection not private' warnings.
- SSL Certificate Authority Choice: For email marketers, be aware that Chrome's policies on SSL/TLS certificates are strict. Ensure that any SSL certificate used for linked domains, including click-tracking domains, is issued by a Certificate Authority that is fully trusted by modern browsers, avoiding CAs with known compliance issues.
