I've installed the SMTP extension from Mageplaza link. And configured it to send from firstname.lastname@example.org, as below.
However it allows for only one email to be configured, as a result despite adding different "Sender Emails" as shown below, all emails get sent out from only the email (email@example.com) that was configured under the SMTP extension.
All sales emails are set to send from Sale Representative (firstname.lastname@example.org) Whilst new account creation, newsletter signup are set to send from email@example.com
But all emails are being sent from firstname.lastname@example.org
How do I get emails to be sent out from email@example.com as well as firstname.lastname@example.org?
