If you copy an email or want to create a new email, it always uses your default email as the sender. Sometimes this causes you to use the wrong sender address for certain recipients. The only way to avoid this now is to always be attentive and remember that I have to check which sender email I'm using.

The proposed idea is: based on the recipient's email, it would suggest that you change your sender email.

For example, if I always receive emails from a bank at alias2, when I'm composing a new email to them, a pop-up would suggest using alias2 instead of your default email.
