I've tried so many Linux email clients - why Aerion just replaced Geary as my top pick

Aerion is an open-source, lightweight, cross-platform (Linux-first) email client reviewed by ZDNET: the article highlights its clean modern UI, support for multiple account types (Gmail, Outlook, ProtonMail Bridge, IMAP/POP, etc.), features like Focus Mode, theming, and basic filtering, and provides installation instructions (Flatpak on Linux and installers for macOS/Windows). The review praises Aerion's simplicity, stability in pre-release, and developer transparency via its GitHub repo, and does not discuss security incidents or threats.
