SecureStamp checks who sent the email and analyzes the message on your device, warning you about suspicious links, attachments and scams before you click.

Yes. Free includes basic protection and trust checks. SecureStamp Personal costs less than a coffee per month.

How does email verification work?

The plugin checks the sender and the message. It shows a simple result first: looks trusted, be careful or high risk. Technical details remain available when needed.

Does SecureStamp access my email content?

Your email text never leaves your device. Message analysis runs locally and only anonymous risk signals may be sent.

How do I register my company with SecureStamp?

Create an account at securestamp.online, add your domain, and complete DNS verification with a TXT record. The process takes less than 15 minutes. Once verified, your emails show the green indicator to all plugin users.

Does SecureStamp protect against phishing?

Yes. SecureStamp detects suspicious domains, typosquatting (domains mimicking real brands) and blocked senders, alerting users before they interact with potentially fraudulent emails.

What do the Gmail and Outlook plugins do?

The plugins install in your browser or email client and automatically verify every email as you open it. They show a trust indicator next to the sender without any manual action required.
