Strange email from Amazon, is it fake?

Hi Everyone,

I got an email, apparently from Amazon, last night. The email states that they are conducting a review of my account. They said they need to verify some details. The email is as below:

We are conducting a review of your account. Within 14 days, please upload the information requested to our secure document upload page: [https://sdu.amazon.co.uk] If we do not receive this information within 14 days, your account may be closed.

When I click the link I get a warning on my web browser stating that it needs to install a certificate and only do this if I trust it.

The email address it ‘seems’ to come from is account-confirmation-eu@amazon.co.uk.

I contacted seller support asking if the email is real or not, and also sent a screenshot of the ’ install certificate message’, but they have sent a generic email pointing me to the help page about phishing on the Amazon site. This doesn’t answer the question of if the email is real or not.

Can someone please tell me if https://sdu.amazon.co.uk is real? When I hover over the link it starts with this and then has a long line of letters and numbers.

I don’t want my account to be disabled, but I just can’t tell if the email is real or not.

I have 0 performance issues. Never had any issue at all in the past.
