An adapter that stores the email locally, using the specified storage driver.

This is especially useful in development to avoid sending real emails. You can read the emails you have sent using functions in the Swoosh.Adapters.Local.Storage.Memory or the Plug.Swoosh.MailboxPreview plug.

Example

# config/config.exs
config :sample, Sample.Mailer,
  adapter: Swoosh.Adapters.Local

# lib/sample/mailer.ex
defmodule Sample.Mailer do
  use Swoosh.Mailer, otp_app: :sample
end
