What Happens If My Email Signing Certificate Expires Before I Renew It?

Once the email singing certificate expires, you won’t be able to digitally sign or send  encrypted emails. What’s worse is that all the emails you previously encrypted and signed  will display a warning message indicating, “There is a problem with this digital certificate.” (Note: Your recipients will be able to read the previously sent emails, though).

Furthermore, some email servers would also show a warning message in the red line on the top or bottom of the email. If you use email to send confidential business information, conduct transactions or marketing outreach, such security warnings can affect the trustworthiness of your emails. Plus, the confidential data you transfer via emails would be vulnerable to data theft. That’s why it’s vital to renew your email signing certificate at least a month before it’s set to expire.

Why Do Email Signing Certificates Expire?

As you know, it is the certificate authority’s responsibility to validate the applicant’s identity before issuing an email signing certificate. What if a business shuts down? What if the domain name and business email IDs are sold or transferred to the wrong person? Imagine how easy it would be for the new owner to send phishing emails or distribute viruses in emails using an original email signing certificate! Recipients will easily trust such “authentic” emails and won’t hesitate to click on anything the email is containing. This would not only spread the malware with ease but also damage the certificate authority’s reputation up to a great extent.

This is why certificate authorities like Sectigo require you to go through the validation process every year — it’s to ensure that the email IDs are still owned and used by the same person/organization as they claim to be!
