A: Hi,

Thank you for the question.

It's Alex, the founder of ProxiedMail.
You can send the new outgoing email from ProxiedMail via the "Contacts" functionality.
You just need to select the proxy email which you would use to send the email, click "Contacts" and enter the address of the recipient.
We would generate a special email (reverse proxy) which you would need to use for sending.
So, the recipient would receive it as from your proxy email.

Example: recipient@tuta.com, reverse recipient-at-tuta-com@pxdmail.com.
You would send it to the reverse lets say from ppk@pxdmail.com via your gmail ppk@gmail.com and recipient would see it as from ppk@pxdmail.com while you actually sent it from GMail.
Might be complicated, but its easier to do than explain. Just try it :)

We don't have an inbox functionality since our goal is to be the thin relay between your real address and incoming communication.
If we build the functionality that would allow you to see the emails straight on ProxiedMail we would just have the conflict of interest with the standard mail providers.
So, we prefer to stay the secure relay for your communication instead of creating the robust functionality within our product.

Thank you.
Let me know if you have any further questions.
