Cloudways does not have an email server. In order to do what you need (having your own email address under your domain), you need to use a forward service which creates email@example.com for you, it then will redirect any emails sent to that address to your gmail inbox. Once connected to your gmail account, you can both send and receive emails under firstname.lastname@example.org.
