Sending out template confirmation emails

Is anyone aware of a stack that all ready has the subject and main body of text complete, where only the email address needs to be completed?

For example - let’s say I have a website or utility that I use to process induction. I have interviewed applicants and need to send out congratulation email and commiseration email, both standard emails but to different email addresses.
I’d like to do it inside my website rather than switching over to my email software.

Lazy I know, but it’s more based on carrying out the whole process fro one place.

The foundation form has this feature.
