Automatically sending an email

Hello friends
I'm new to the community
Thanks for this active community

At different times of the month i need to send reminder emails to all of my Sales reps to remind them to do something. I would like to automate this.
I have searched the net but cannot find something that works in Outlook 2010 (other than pay solutions, problem with pay solutions is my company will not allow untested third party apps on their network)
If anyone can point me to the right website or provide a solution i would be truly grateful.
My current solution is just a reminder, telling me to send the email.

maybe this?

Oh no
This is Excel program
I want to set myself in the outlook app

I do not want to use monetary systems

Can I do this in outlook?
