I tried to email the email address you provided for Maricopa county, To: covid19vaccines@maricopa.gov , but it comes back as invalid address and undeliverable. How is one supposed to get answers if you provide incorrect contact info?

My question is this. I saw tonight on the news that essential workers were put into group 1b and I am considered an essential worker as uber delivery driver. How will I get notified when I am able to get mine?
