Need messages sent to 4 different emails individually

Hello.

I have a contact form on my company website with a drop-down that has 4 different email options.

What I need is, based on what selection the user selects, that an email be sent to that particular email address and that address only.

For example, if we have someone interest in our jobs, they need to select our “careers” email from the drop down. Right now, if I select “careers” and send a message, all the email addresses in the contact form receive it.

Suggestions? Advice? Need help.
