(KCEN) -- If you're planning on shipping holiday packages this season, beware.
Consumer watch dogs have issued a warning about bogus emails claiming to be from the post office.
The emails contain false information about a package that could not be delivered by USPS.
Officials say to look closely at the emails. Some of the grammar and the spelling in the bogus emails is incorrect.
Also, USPS says it will never send an email regarding packages it cannot deliver.
Fraud Specialist Beth Schell said, "So basically the consumer needs to be aware of receiving any emails they don't solicit with instructions to click."
Experts say if you do click in an unsolicited email, it could activate a virus that can steal your personal information.
Keep in mind, the only way the postal service will get your email address, is if you sign up on their website.
