Help with replying with unmasked email

Hello, I have email forwarding set up on my domain. yy@xx.com goes to yy@gmail.com. If I were to reply to an email sent to the xx domain, it would show up as the gmail domain to the sender. I was wondering if there is a way to reply via the xx domain. I tried following the tutorial without any luck.

That would require a dedicated email address, which is not available on the free plan. You can upgrade to premium, where this is available, or setup using Cloudflare and Zoho.

So, just to clarify, I can forward but not respond. To respond I have to upgrade to a paid plan?

Correct. Or you can setup with Cloudflare and Zoho.

If you forward xyz@domain.com to personal@gmail.com you can create a reply from using Google check out the tutorial section.
