email notification of login to 1Password

This morning I got two emails from 1Password in my gmail account: "New Sign-in: your 1Password was just used to sign into (name of my account) from 1Password for Chrome" and the same message except for "Safari". I don't recall ever having seeing these kinds of emails from 1Password and I've spent the last hour trying figure out if someone hacked into my 1Password account. What is going on here? Is this something I should expect everytime I sign it to 1Password?
