Change Account in Automator when Scheduling Email

Hay guys,

Let me know if this is already a subject and I'll remove this post.

I am looking to schedule emails using Automator and have been ablate send from my personal account (iCloud). I am looking to send emails from my work account (G-Suite) through Automator but I am unable to change the account when selecting a New Mail Message. Is there a way to change the account?

Let me know if there are any questions.

Thanks all.
