Help installing this on ubuntu 22.04

[eliander30]

Hi I'm trying install it on ubuntu 22.04 but when i execute the command to install it i see the following error

go get -u github.com/AfterShip/email-verifier

go: go.mod file not found in current directory or any parent directory.
	'go get' is no longer supported outside a module.
	To build and install a command, use 'go install' with a version,
	like 'go install example.com/cmd@latest'
	For more information, see https://golang.org/doc/go-get-install-deprecation
	or run 'go help get' or 'go help install'.

NOTE: i also used the gollowing command but is not working neither

go install github.com/AfterShip/email-verifier@latest
package github.com/AfterShip/email-verifier is not a main package
