An adapter that stores the email locally.

This is especially useful in development to avoid sending real emails. You can read the emails you have sent using functions in the Swoosh.InMemoryMailbox 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
