To delete a single Drip account, you will want to first make sure you are signed in to the account you'd like to delete (if you have more than 1 account).
If you need to perform an account export, do so before you delete the account. Once the account has been deleted, all data will be lost.
Go to Settings > Account > Delete Account > click Delete Account button.
When you are certain you wish to delete your account, click the I’m sure, delete my account button.
