Send email from console

Send an email from the Rails console (e.g. for testing purposes):

ActionMailer::Base.mail(
  from: "from@example.com",
  to: "to@example.com",
  subject: "A test email",
  body: "This is a test email to test email delivery.",
  delivery_method: :my_email_service_api
).deliver_now

Remove delivery_method if you only have one and did not configure special delivery methods.
