Costco Citi Visa reward certificate is in the mail/email

I just received a Costco City Visa reward certificate amount of $358.14 in the email. I recently switched my monthly statements to paperless. This is the first time receiving certificate in email. I have been always receiving these checks (certificates) in paper via US Postal Service.

I am guessing they will send paper copy of certificate to those who receive paper statements (?). That’s my educated guess.

Anyway, checks are in the mail/email.
