A fake Capital One email opens with Sir or Madam, demands a reply and links to a payment update.
Capital One’s page on phishing says emails that sound overly urgent, use generic titles such as Sir or Madam, or invite you to click links to update payment information are warning signs. The email below is invented, and each number is one of the signs.
Example
Dear Sir or Madam,
We could not process your last payment.
Respond right away, or your card may be limited today.
Update your payment information with the link below. You do not need to sign in.
The button says capitalone.com/update-payment
The sender's address does not match Capital One.
The display name says Capital One, but the part after the @ belongs to someone else. Capital One says to be wary of emails that come from addresses that don't match the names of the companies supposedly sending them.
A generic title instead of your name.
Capital One says emails or texts that use generic titles such as Mr., Mrs., Sir or Madam instead of your legal name are a warning sign.
A demand to respond right away.
Capital One says emails or texts that sound overly urgent and ask you to respond right away are a warning sign, and to resist the pressure to act immediately.
A link to update payment information without signing in.
Capital One lists emails that invite you to click links to update payment or access account information, and links that ask for information without signing in through the secure site.
A button that says capitalone.com and goes somewhere else.
Capital One says to watch for links that lead to a site that looks familiar but has a web address that is incorrect or has subtle differences.

Read the sender's address from the right, because the last two parts say who owns it.
Anyone can put “Capital One” in front of an address. The part to read is the domain, after the @ in a sender or after the https:// in a link. Read it from the right: the last two parts name the owner, and everything in front of them is only a label the owner chose. Capital One’s security pages are at www.capitalone.com, and the owner of that address is capitalone.com. Capital One says to check that texts and emails come from its usual email domain and short code, but the pages we read do not list them.
Read the domain from the right
www.capitalone.com
From Capital OneOwned by capitalone.com. This is the address of Capital One's own security pages.
capitalone.com.payment-update.example
Not from Capital OneOwned by payment-update.example. capitalone.com is only a label in front of it.
capitalone-account-desk.example
Not from Capital OneOwned by capitalone-account-desk.example. The name has Capital One in it, but the owner is someone else.
