Hello @Jennifer595,
Some valid email address endings are listed in the article below.
I have in the past received an email from hello@aribnbmail.com with an offer for bookings in Sonoma. The "Book now" button in it did point to a valid Airbnb webpage. The browser showed the padlock symbol and the page connection was a secure one to airbnb.com
How do I know if an email is really from Airbnb?
As always you should check the email "from" address very carefully, check the text that it's correct English or whatever language, and that it's not asking for information that Airbnb should already have e..g. bank or credit card information.
Steve.
