SMTP how to change the display name of emails?

Configuration
1

This is my email configuration:

# SMTP Gmail notification
notify:
  - name: "gmail_xxx"
    platform: smtp
    server: "smtp.gmail.com"
    port: 587
    timeout: 15
    sender: "[email protected]"
    encryption: starttls
    username: "[email protected]"
    password: "MEH"
    recipient:
      - "[email protected]"
    sender_name: "Home Assistent"

It works fine except on my email client, the email is always received by [email protected]. I would like it to say “Home Assistent” instead. I thought that was the point of the sender_name parameter but it does not seem to do anything?

Try:

sender_name: "[email protected]"

Tried that, same result I’m afraid. I also inspected the email headers, it looks like this in my email client (protonmail)

From: Home Assistent [email protected]

Could it be something with protonmail perhaps? But it works for other emails, for example this forum.

As a side note, I guess it is not possible to set an email icon either? Would be nice if received emails had the home assistant logo.

Strange, looks fine in gmail. Guess it is protonmails fault then.
