Setting up mail send/receive with google domains and digital ocean
I have a domain "example.com" through Google Domains. Since I'm using Digital Ocean's DNS, I can't use google domain's send/receive for emails like "firstname.lastname@example.org." I get a message: "It looks like you've changed your name servers. All settings for your domain (including website, email, synthetic records and resource records) are currently disabled. To enable these settings, you will need to restore the Google Domains name servers." Which makes sense since I'm using DO's nameservers.
My question is: how can I send emails from the gmail client that appear to be sent from "email@example.com" and receive emails sent to "firstname.lastname@example.org" appear in the gmail client? I don't want to host my own mail server because I won't be able to manage it and there's a lot of headache/unsafeness there.
