What is the best way to distribute services between email accounts?

Question

Email

There was a project and the need to register in a variety of services, until now everything was registered to one mail. In addition, there are employees who sometimes need to provide access to mail. I am the main and all key services on me
How to distribute services such as:
- Social networks (personal and for the project)
- Hosting
- All rubbish at a time, which can sometimes come in handy (forums, sites where registration is required, etc.)
- App Store, Google Play
- Payment systems
- Other categories
Requirements for the organization of boxes:
- There should not be many of them, so as not to remember what's what and where
- Normal security, for good boxes should not be dependent on any one
. It's clear that it is necessary to distribute it to a personal box and a worker.
But, such important services as payment systems and the App Store, Google Play are strongly tied to my person and keeping 3-4 mails only for my letters is not very good. Should I keep them in my personal mail?
At the same time, it is known that Google can ban an account and a lot will go down the drain
----------
Briefly, just share how you organize similar things, what rake you stepped on

Answer 1

I have a personal domain with email attached, and I manage how I want, as well as an unlimited number of mailboxes
