Installing Glassmail

Download Glassmail

Requirements: macOS 14 Sonoma or later, on an Apple silicon or Intel Mac. Free for 14 days.

Steps

1. Find the download. It’s called Glassmail.dmg. Click the Downloads stack on the right of your Dock, or open Finder and choose Downloads in the sidebar. In Safari you can also click the download arrow in the toolbar.
2. Open it. Double-click Glassmail.dmg. A window opens showing Glassmail and your Applications folder.
3. Drag Glassmail onto Applications in that window. This copies it to your Mac.
4. Open Glassmail. Open the Applications folder and double-click Glassmail. You can also find it in Launchpad, or press ⌘ Space, type “Glassmail” and press Return.
5. Click Open if your Mac says “Glassmail is an app downloaded from the internet”. That’s a normal check for every downloaded app; Glassmail is checked and notarised by Apple.
6. Optional: in Finder’s sidebar, click the eject button next to the “Glassmail” disk. You can then put Glassmail.dmg in the Trash.

If you opened Glassmail straight from Downloads, it offers to Move to Applications. Choose it: that’s where you’ll find Glassmail later, and where it can keep itself up to date.

Next, add your first account. If you need help with that, see the setup guides for Gmail, iCloud, Yahoo, Outlook, Fastmail and custom domains.

If something goes wrong

“Glassmail can’t be opened” or “is damaged”

The download may not have finished. Delete Glassmail.dmg, download it again from glassmail.app, and repeat the steps. Only ever download Glassmail from glassmail.app.

I can’t find it in Launchpad

Open Finder, choose Applications in the sidebar, and look for Glassmail there. If it isn’t there, go back to step 3.

Uninstalling

First remove your accounts in Glassmail › Settings › Accounts, which also removes their passwords from your Keychain. Then quit Glassmail and drag it from Applications to the Trash.
