No description of Instantly.ai yet.
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. Putback is a menu bar window manager for macOS that fixes this. It learns where your windows sit while you...

As answered by people managing Instantly.ai 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.

Apollo now ships email warmup and inbox rotation too, so the difference comes down to volume economics. Instantly charges by emails sent and lets you connect unlimited inboxes, while Apollo charges by seat and credit.

Anywho, the old mailgun system was able to send emails immediately + had images in them. The recommendations we got were to remove ALL images, and instantly.ai has to delay a few minutes between email. So the emails get out slower and no... Source: about 3 years ago
