Large syncs and first-time imports used to be able to overwhelm machines with limited RAM emails were processed all at once, which on an 8 GB Mac could push the system into heavy swapping and slowdowns. Email processing is now paced to stay light on memory regardless of how many messages are queued, so your inbox keeps filling in without freezing the rest of your system.
Improved: Your account and AI preferences now live together in one streamlined Settings spot no more hunting between separate menus for what you want to tweak.
Fixed: Setting Quartz as your default mail client and clicking a mailto: link no longer freezes the app your compose window pops open smoothly, every time.
Meet Signatures your personal sign-off, always ready to go. Create as many as you like in Settings, then pick the right one straight from the compose window. Quartz drops it in automatically, keeps your reply quotes intact, and remembers your choice per account, so every message ends exactly the way you want.
