Notification kit · v 1.0 · 14 May 2026

Twelve emails.
Twelve quiet notifications.

Plain, useful, restrained. No exclamation marks, no emoji, no clever subject lines. Built from the same tokens as the rest of the system — fonts, colors, spacing, radii. Postmark for transactional email, OneSignal for push, Twilio for SMS.

Principles

One channel per moment
Important things go on the channel the user actually checks.
Booking confirmations are email + push. Reminders are push only. 2FA is SMS only. We never send the same message on three channels at once · that's how people start ignoring us.
Subject lines are descriptive
No clever phrasing. The subject is the news.
"Sarah confirmed your session · Wed 20 May" beats "You're set!" every time. The user reads the inbox preview, not the email body · make the preview do the work.
One CTA per message
The dark button is the action we want.
Secondary actions appear as plain text links below the cta. Two big buttons split the user's attention and halve click‑through · we measured this.
Receipts in the message
Don't make the user open the app to see what changed.
The summary-box repeats the date, amount, and reference inside the email itself. Phone screens, slow networks, offline subway commutes · the message should be useful on its own.
