Multiple Senders for One SMTP

[JonathanDragonDJ]

How can I add multiple emails to a single SMTP like SendGrid. I have two businesses that email from the same account but different emails. Do I have to add each email as a new SMTP connection with the same settings or is there a way to add more sender emails?

Kindly create a new delivery server for the second email address.
