Is the mail that came from gaia bounces google com legit?

Is there a possibility that this email from gaia bounces google com is not phishing Maybe, this seems like a legit email similar to the one you recieved, even though the email seems on first impression to be very likely to be spam.

• How should I respond to suspicious emails
  
• Do not click links in the email
  
• Navigate to the site mentioned manually
  

In this case googling google security checkup gives a link to https://myaccount.google.com/security-checkup/1?pli=1 The advice from the link above seems to mirror this: Holmes stressed that when someone receives an alert like this, the right thing to do is to first “take a deep breath,” and then open a new browser window and manually type and navigate to the settings of the service in question (in this case, to myaccount.google.com/security-checkup) and see what’s going on there, without ever clicking on the link in the email.
