From Address

Hi community!

I need your advice on our client's need.

We use the domain "https://e.sampledomain.gr" for the branding.
Now, our client wants to use the "sampledomain.gr" in the from address for example info@sampledomain.gr.

Is there any way to add the domain, instead of subdomain, without creating a new brand?

Thank you in advance.

Regards,

Nafsika
