Auto Email scheduler/sender required

Afternoon all

I am after a plugin that will automatically send emails based on some simple requirements. I require this is send from a domain name that I own in order to have a check in place that both outgoing and incoming email service status are working. i.e set a automatically scheduled email from a domain name, to send twice per day to 1 recipient to help capture when the emails could be down.

– set the frequency and time (daily, weekly, 10am etc)
– the subject/content
– recipient of the emails
