Verify carriers from your inbox.

The extension checks the sender domain of incoming carrier emails against official registry data, so you spot impersonation before you reply. Set up with our team, on a custom plan.

What the extension does

Domain identity check

Matches the sender domain against the carrier's authoritative domain from official sources.

Works where you work

Runs in Gmail and Outlook. The verdict appears next to the email, with no tool switching.

Set up with our team

We configure the extension for your mailboxes rather than leaving you to install it. Part of a custom plan.

Or straight into your TMS

The same checks can be delivered inside your transport management system. We build the connector for your setup.

Spoofing detection

Flags emails where the sending domain has no verifiable link to the company named in the signature.

No manual lookups

Runs automatically for every new sender. You only see a result when it matters.

Try CarrierGuard on your own carriers.

We will run live checks on carriers you actually work with and show how CarrierGuard fits your current workflow.
