What is the best way to organize the acceptance of online payments?

Question

Payment systems

Hello.
I want to ask advice from those who had a similar experience.
Task: to organize the acceptance of online payments on the site for the sale of courses/coach services.
Site on WordPress. It contains pages describing courses and other services. The client leaves a name and e-mail, enters the subscriber base and an automatic letter with payment instructions is sent to him.
The client goes, pays. There should be segmentation in the contact database (paid / not paid) so that you can send the next letter with access links only to those who paid and “boosters” to those who think.
It is important that the process is as simple as possible for the client.
What options
did Unisender + Yandex.Checkout consider.
Unisender because I already worked with him. They have integration with Ya.Kassa, but, unfortunately, there is no segmentation. Otherwise, I wouldn't have asked.
I also looked in the direction of robo.market in terms of organizing payment for courses, but again, he is not friends with the unisender.
Now I'm watching Justclick. He seems to offer it all. But I would like to learn about other solutions and experience from those who have implemented something similar.
Thanks in advance!
PS I don't know how to code

Do not forget about 54-FZ. You need to issue a check to an individual as soon as you receive payment from him. Yes, on the website too. Therefore, look towards those solutions where there is such an opportunity, for example, Yandex.Checkout.
In the module-bank , they now give an online cash desk for the ruble, of course, they will need to pay for RKO.
