What this page cannot tell you
Is the person emailing you really WILLIAMS TANK LINES LLC?
Most double brokering starts with a real carrier's MC number in someone else's email. You just checked the record by hand. HauLens does it inside Gmail on every carrier email, and checks the part no lookup can: who is actually writing to you.
- This record opens by itself beside every carrier email, before you finish reading it.
- The sender is checked against the contact FMCSA has on file for WILLIAMS TANK LINES LLC, plus how old their email domain is.
- Your reply is already written from the load they are asking about. You read it and hit send.
Free during beta. From the Chrome Web Store, two minutes to set up. The text of your emails never leaves your browser.
