Give Spike its own notification sound on your Mac

Why Spike notifications still blur together on a Mac

Spike turns email into chat, and its Priority Inbox already keeps newsletters and receipts out of your face — that's half the battle won. But everything Priority does let through arrives with one sound: macOS plays a single alert chime for every notification and only lets you switch an app's sound on or off, never change it.

So the client reply you keep checking for sounds exactly like a colleague's FYI. And chat-speed email raises the stakes — more messages, smaller messages, all sharing that one chime.

What you can do without TrillMark

• Spike's Priority Inbox. It sorts the mail that matters from the “Other” pile, and that's the right first pruning — less notifies you at all. But it doesn't change how anything sounds.
• Spike's notification settings. You can choose what notifies you, per account — Priority only, for instance. Again: which messages, not what they sound like.
• System Settings › Notifications › Spike. Toggle the sound on or off and pick banner vs. alert — but there's no custom sound, and no way to make one sender louder than the rest.
• Do Not Disturb or a Focus. These quiet everything while you concentrate, but that hides the reply you're waiting on rather than making it recognizable when it lands.

How TrillMark makes the thread you're waiting on stand out

Spike has a native Mac app, so TrillMark reacts to the banner it already shows. Add Spike, give it a sound and a color, and because TrillMark can read the notification's text, add a rule for what you're actually waiting on: the text contains a sender's name, or a word from the subject — “contract,” “invoice,” the project's name.

So that one reply arrives as a louder sound you recognize plus a colored flash labeled with the app's name, while the rest of Priority stays soft. Spike decides what's worth showing you; TrillMark decides what's worth interrupting you.

It reads that text only on your Mac, only to decide how to react, and never sends it anywhere.

Set it up in about a minute

1. Open TrillMark and add Spike from the popular-apps list or a recent alert.
2. Give it a sound you'll know by ear and a color; TrillMark labels the flash with the app's name.
3. Add a rule for the sender or subject you're waiting on — the text contains their name or a keyword — and give it a louder, more distinct sound.
4. Optional: let the rest of Priority use a soft tone, so only the thread that matters today reaches you by ear.
5. Turn off the system sound for Spike in Notification settings so you hear only the sound you chose.
