Multiple email accounts on android

[Feasty]

I've got some email accounts I like to keep track of on my android mobile, and my preferred way is to have 1 inbox view showing all the received emails - but I want it to be obvious which account the email is being received by.
Does anyone know of an email app that does this?

The closest I've got is Samsung's own email app which shows a small colour circle next to the email, and you can set the colour. It's still very minimal on the screen though and not easy to tell similar colours apart.

I've tried trawling through the Play store apps, downloading several and setting them up but no joy. Googling around brings up the question many times over the years yet I'm surprised there doesn't seem to be an answer anywhere.

Not sure why you cant use Samsung`s, works fine for me,
After a few days you work out what each circle is for due to the nature of the email it gets

You can add multiple accounts into Outlook. Nine is also another really good client.

Samsung's circles are small and not easy to tell the difference between the colours at a glance.
Outlook doesn't easily differentiate between different accounts either - thanks for the ideas though. I'll give Bluemail a go and see how I get on
