how not to confuse separate email providers

[THAIPHUKET]

I set up email acc with @tuta.io.   (https://tutanota.com). 

How can I send and receive in my Gmail window or any other window

@tuta.io messages.?

And not to confuse in the reply  @tuta.io with @Gmail

that could cause  some funny consequences.

How best// to make sure that that does not happen?…

Much obliged.

Out of interest, why did you do that?
