Arranging a paid wordpress subscription?

Question

WordPress

Hello. There is a task to launch paid subscriptions on the site. I will describe below what is needed.
Cryptocurrency direction theme and trade.
There are certain paid foreign services where you can subscribe to the newsletter. They randomly send information to the mail at different times, what needs to be bought or sold on the market at the moment. You need to automatically post this information from the letter when you receive it to a certain mail on the site (removing extra information from the letter - links, signatures, etc., leaving only the body of the letter - for example, now you need to buy a cue ball at a price such and such and sell it at such and such). On the site, access to this information should be available only by subscription (subscriptions are different, demo access, week, month, changed price after 2 months in a row, for example, etc.). Basically, that's all.
What I already found:
1. To automatically post information received by email to the site, you can use -
https://jetpack.com/support/post-by-email/
I read it, it seems to be suitable for this task.
2. For a paid subscription, the site offers many different plugins. Haven't found a specific one yet.
At the moment, the question arises, will it all be integrated and synchronized with each other? That is, a letter has come to the post office, it is automatically posted on the site and a user who has a subscription can immediately see the information. And plus, he should immediately receive a notification that a post has been posted. Since he must quickly respond to it. Because this information may not be relevant in a few minutes, the odds for selling or buying, for example, will change.
Or maybe there is an easier way, somehow for those who are on a subscription, to send information from a letter to them by mail. Can you please tell me the easiest way to do it? Or do I need to order some kind of special script for these tasks, or am I just bothering and there is nothing complicated there? Thank you.

Answer 1

There is nothing complicated here, only 3 operations:
- take money for a subscription
- read the body with a letter and post it on the site
- notify users about a new post
Plug-in for subscription, take any one that suits the task and likes it.
100% there is a plugin that either notifies you of a new post, or sends it entirely by mail. Let it send even to those who do not have a subscription (announcement or something like that) - it will once again remind you that you still need to buy a subscription.
