On lemmy? No. The devs decided to do a single page app with a REST API, which leads to the sluggishness and slow load-time. kbin (which is compatible with lemmy’s content) is your best bet, IMHO. https://kbin.fediverse.observer/list
I’m too used to lemmy unfortunately, and kbin is far from perfect.
Hosting a mail server is really easy. Making sure Hotmail, Gmail and others accept your emails is a nightmare.
I don’t host my own email, I just delegate my email management to a small provider.
