Considering the switch to murena's email service

Hi! So I’ve been debating for a bit switching from protonmail to murena’s email service. Not that there’s anything wrong with protonmail. It’s more of a problem I have with the official client with it’s dependency on google play services for notifications (I am aware microg works but I’d rather not have my email client depend on such services anyways)

So what I’m asking is if it’s reliable? What are people’s experiences with it? Cause I want to make sure it is reliable before a switch is made

UPDATE: I started to get pretty comfortable with murena so I went through with the change
