RELATED: If You Get an Email From the USPS With These 3 Words, Don’t Click on It. If you’ve received an email from Costco and T-Mobile in the last month or so, you’re not alone. Snopes, a fact-checking website, reported on Feb. 10 that it had reviewed multiple emails recently sent, claiming to be from both companies. The messages promise a “gift” or “exclusive reward,” with a subject line that usually reads “We have been trying to reach you—Please respond!” According to Snopes, two of the “exclusive reward” emails they reviewed were marked with the Costco name and pink T-Mobile coloring. “Congratulations! You have been selected to get an exclusive reward from Costco and T-Mobile,” the body of these messages says. Costco and T-Mobile have not teamed up for an exclusive email giveaway. According to Snopes, any message claiming to be from the two companies is a scam. The links provided in the emails reviewed led to a British internet domain, which then redirected to a Russian website. “On this page, users were then told they could receive a $100 Costco gift card for taking a survey. However, this was also part of the scam,” Snopes explains. A Florida mailing address was included at the bottom of the fraudulent emails as well, but it has no affiliation with either of the companies. And Snopes said it has also seen this address at the end of messages in similar scams for businesses like Lowe’s and UPS. “In sum, we recommend that readers delete any emails that claim to be from both Costco and T-Mobile that promise an ’exclusive reward,’” the fact checking site advises. “These were not official messages from either company.” RELATED: For more news on retail scams, sign up for our daily newsletter. Scammers consistently try to target victims by fraudulently posing as various retailers. “It is an unfortunate fact of the Internet that at any given time there are numerous illegitimate pop-up ads, surveys, websites, emails, social media posts and advertisements that purport to be from or authorized by Costco,” the company warns on its website. “It is unlikely that Costco is affiliated with these promotions.“ae0fcc31ae342fd3a1346ebb1f342fcb Costco says it will never send unsolicited electronic communications that ask for a user’s personal information like their username, password, credit card information, birth date, or Social Security number. One of the first things you should when receiving a “Costco” email is check to see who sent it, as verified messages won’t include typos and misspellings and will have an address that ends with @costco.com. But if you’re not sure of the email’s legitimacy, there are ways to make sure you’re protected no matter what. “Enter websites using your browser and not by clicking on provided links,” Costco recommends, adding that you should never respond to emails that cannot be verified, and never provide personal information through email. Scammers will try to pose as certain phone providers, like T-Mobile, as well. T-Mobile said that it is common for fraudsters to send an email that appears to be from the company in order to trick them into providing personal information directly or by visiting a phishing link. “T‑Mobile will never ask you to confirm or verify your sensitive personal information in an unsolicited e-mail,” the phone provider warns. “Never confirm or verify your sensitive personal data or account information in response to an unsolicited e-mail, text, or inbound call … You should only provide such information to T‑Mobile or any other account provider when you have initiated the contact to a known, reliable contact number or address.” RELATED: If You Get This Message From Netflix, Delete It Immediately, FBI Warns.
