       version: ~> 0.5.0

2. Run shards install

Set an instance of Halo::Adapter as Carbon's adapter:

require "carbon"
require "halo"

abstract class BaseEmail < Carbon::Email
end

BaseEmail.configure do |settings|
  settings.adapter = Halo::Adapter.new(
    host: "smtp.domain.tld",
    port: 587,
    username: "[email protected]",
