4 Red Flags to Spot
Look for Your Name
THE RULE:
A real bill always greets you by Name (e.g., “JOHN SMITH,”) at the very top.
THE TRAP:
Scammers often skip the name because they don’t know who owns the email address.
Check the Sender
THE RULE:
Real billing emails only come from marktwain-noreply@smarthub.coop. Emails from our team use @marktwain.coop
THE TRAP:
If it comes from @gmail.com, @yahoo.com, or anywhere else, delete it.
Watch for False Urgency
THE RULE:
Real utilities do not panic you with 30-minute timers. We always provide prior notice by mail.
THE TRAP:
If an email demands you act in minutes, it is a scam.
Hover Before You Click
THE RULE:
Hover over the link. It must start with portal.marktwain.net or marktwain.smarthub.coop.
THE TRAP:
If it says ANYTHING OTHER than the above like marktwain.dudaone.com or weebly.com, don’t guess—use the App.
