Thank you for sharing! This sounds like a phishing attempt. So we can confirm, do you mind replying to this thread with the email address used?
To clarify for anyone else that comes upon this thread, if you receive an email that you believe is a phishing email pretending to be Shopify these are the steps you can take:
IMPORTANT Do not click on any of the links in the email. Do not provide your account information, bank information or any other sensitive information through the email. There are rare situations where Shopify may require you submit sensitive documents and 99.99% of the time that will be done directly through your store admin using a secure upload feature.
Please review our Help Center information for confirming if an email is real or fake: Protect your account against phishing. In situations like this we ask that you please send this email as an attachment to our Safety and Security team at safety@shopify.com. It is important to ensure that you are including the headers with that email as our team uses that to trace where the email came from. If you aren’t sure how to do that, you can follow these steps from Google.
Please let me know if you have any further questions!
