Normally you use your e-mail and a password to Pinterest, some times you use Facebook to login..
that should help, have a nice evening over there

To deactivate your account:

1. Log in to Pinterest.
2. Click your profile button at the top of Pinterest.
3. On your profile, go to the bolt button.
4. Click Deactivate Account at the bottom of Account Basics.
5. Select the reason you'd like to deactivate your account.
6. Confirm that you want to deactivate your account.

Hi
This may mean that your Pinterest account has been hacked or that it is a scam to get your details from you.
I suggest that you log onto your Pinterest account and check that all your details are still there and correct. If they are then the email should be ignored and deleted without taking any further action as it is a "phishing" email.
It is possible however that you may not be able to get into your Pinterest account with your usual login details or that on checking you find the details they are holding are not correct. In this case you need to change your Pinterest and email login details, especially passwords and let Pinterest know that you have been hacked.
Hope this is helpful, if so would you please register that with Fixya
Cheers
