Every time your display setup changes, macOS moves your windows and does not move them back. Undock from a monitor and everything piles onto the laptop screen. Dock again and it stays piled.

As answered by people managing eM Client and Putback.
Putback's answer:
Mac users who move between display setups: a MacBook that docks to a monitor at the desk, a second screen at the office, a laptop on the couch. Developers, designers and anyone who runs a lot of windows and is tired of putting them back by hand every morning.
Putback's answer:
Most Mac window managers snap windows into place when you ask. Putback remembers. It learns where your windows sit while you work, keeps a separate memory for every display setup, and puts everything back when that setup returns. Named Scenes, drawn in Scene Studio and switched with one hotkey, turn any arrangement into something you can recall in a second.
Putback's answer:
Rectangle and Magnet are great at snapping a window to half the screen, and Putback runs happily alongside them. Choose Putback if your problem is that your windows get scrambled every time you dock, undock or plug in a monitor, or if you want whole desks you can switch between with a hotkey. It is a one-time purchase with a 7 day free trial, no account, and your window data never leaves your Mac. On first launch it even checks your Mission Control settings and tells you if the free macOS fix is enough before you pay.
Putback's answer:
A native macOS app in Swift and SwiftUI, using the macOS Accessibility API to move windows and Sparkle for updates. Licensing and the website run on Cloudflare (Workers, D1 and Pages).
Putback's answer:
Putback launched in July 2026 with a simple pitch: unplug your MacBook and macOS piles every window onto one screen. The launch post passed 60,000 views and the replies split down the middle, half saying "I've needed this for years" and half saying "my Mac already does this." So we went and found out. The real answer is two Mission Control settings most people never touch, and we published that free fix ourselves. Even with those settings, restores still fail when a dock reconnects slowly or an app resists being moved, and nothing in macOS remembers more than one desk or lets you name a layout. That gap is Putback. About half of its first features came straight from those launch replies.

One point in eM Client’s favor is its free version. However, its features are pretty limited. For example, you can only use it with two email addresses, and the only customer support option is the user forum.

Also, if you're also trying to use Xtra email in Microsoft Outlook, also expect problems. Outlook is also crap. There are other email application options. Em Client (emclient.com) is an excellent alternative to Outlook. Source: about 3 years ago
