Any solutions to test email received content using a stable email address on cypress 10?

[MatiDiez]

I'm working with Cypress 10, and before this I was using gmail-tester integration to test some stuff but it doesn't work anymore with javascript + cypress 10 and refactoring will be a lot.

I have found a solution using ethereal email, nodemailer, and a couple of more plugins and it works perfect for initial interactions, like verify my email, change password, etc. Provided I'm working with a new email account everytime. My problem is that I have many test cases that require me to work with a fully populated account from my app so It is not viable to create everything each time.

So my question is, do you know of any solution, post, plugin, document that could help me figure this one out?
Essentially I need to always use the same email address, and be able to access the emails on that mailbox. No matter the service, if it is local or remote. Only thing that matter (for now) is that is free cause I didn't get any budget for this one.

Thank you!
