Calling a method after deliver

Hi, I am trying to call a method after message is delivered via
MyMailer.deliver_message. Is the below the same as this?
MyMailer.deliver_message
create_sent_record?

class MyMailer < ActionMailer::Base
def message( subject, body, recps, sent_at =
Time.now)
@subject =subject
@body = body
@recipients = recps
@from = ‘[email protected]
@sent_on = sent_at
@headers = {}

create_sent_record # is this being called after

MyMailer.deliver_message???
end
end
