Profit share is in the introductory paragraph, and the key, but is not present on any of the email providers. This makes the guide feel unreliable/poorly made. If it's present to be used in a future version, or referential to other guides, that should be noted to avoid confusion. The purpose of including "Profit share" is unclear.

It could be made clear, but if your comment was a question: it's because there is no profit-sharing e-mail provider (yet).
That's the inference I made. I should've been more clear. I was providing feedback on the clarity of information presented. I would make the edits myself, but am unskilled with editing software, and a simple white-out would look pretty jarring given the positioning. The message (no profit sharing email provider) is still communicated, but sloppily.

I was using Spark mail (https://sparkmailapp.com/) client for Outlook and iCloud before I switched my current provider, can recommend but don't know which of the mentioned providers it works with.
I disagree GMX is not in the eco-system tier; they have a calendar, drive app and online office suite. It's not as extensive as some others but their service includes more than just email.
