Hello @Jason2342
If I received your inquiry I would message the guest back and ask whatever vetting questions you have in place to see if the guest is a good fit for your place before making a decision. Like yourself, many guests are new to Airbnb so this isn't necessarily a red flag.
As a new host I would suggest you keep to bookings for not more than two weeks until you becoming familiar with how Airbnb works.
You don't receive a guests email ever. And you don't see their photo until after they book.
Do have a look at the Airbnb Help website as it has FAQs about most aspects of managing your STR business on Airbnb. It's good to familiarise yourself with how Airbnb works before letting your listing go live.
For example it would show you how a booking request works
