send email and track as activity

hello oro people, after diving deeper we progress with our project, next is sending of emails inclusive tracking as activity, emai sending and tracking via oro-ui works, email sending using oroEmailProcessor works and parses nicely and easily the email template

so i succesfully send emails using this processor:

Oro\Bundle\UserBundle\Mailer\BaseProcessor.getEmailTemplateAndSendEmail

my question is:
how to create an activity entry for that?
(without too much boilerplate code needed to write, is there a getEmailTemplateAndSendEmailAndTrackEmailActivityForUser() ????)

– side question where can i look into the spool of current emails waiting to be send
