When did your email client start feeling too busy?

I spend most of my day in email, and the tools I tried kept getting bigger. More sidebars, more dashboards, more features I rarely touched.

That is why I started building Orvia Mail. I wanted a native Mac inbox that could handle Outlook, QQ Mail, 163 Mail, Gmail, and custom IMAP without turning email into another workspace to manage.

I am curious about your experience. What is the one feature in your current email client that genuinely helps, and what is the first thing you would remove?
