Delivery channels

What it is

Every notification is delivered through up to three channels:

In-app notification centre: always on, always stored. This is the canonical record.
Push notification: on iOS and Android, subject to per-type preference and to the OS-level permission.
Email: on any platform. Default cadence is immediate (one email per notification); members can opt into a daily, weekly, or monthly digest instead.

You configure push and email per notification type for most categories. A small set of always-on notifications cannot be fully silenced; see Always-on tiers.

Who can use it

Member: sets push and email preferences for the types they receive; chooses digest cadence.
Admin: same, plus admin-only types (payment-account state, booking requests, expense submissions).

Where to find it

Notification centre: /notifications. The in-app list.
Notification preferences: /settings/notifications. Email Digest toggle + Important section + per-type Push/Email toggles.

Preferences screen layout

Section	What it controls
Email Digest	Collapsible card with an on/off switch. Off (default): emails fire immediately. On: a cadence radio (Daily / Weekly / Monthly) sets when batched emails go out. The Important section’s emails ignore this setting and always fire immediately.
Important	Two summary rows, Compliance and Critical, covering the 12 always-on types. Email is locked on for both rows. Push is locked on for Compliance; user-toggleable on Critical via a single aggregate switch, with a confirmation dialog when you turn it off. Each row has a “Learn more” action that opens an in-app explanation of that tier.
Notification types	Per-type Push and Email toggles, grouped by category (Squawks, Bookings, Assets, Maintenance, Documents, My Documents, Finance, Governance, Account). Rows only you can see because you hold admin somewhere are marked with a small icon. Push column hidden on web.

Channel details

Channel	Where it is delivered
In-app notification centre	Every notification, always, server-stored. Unread badge on the notifications tab.
Push (mobile)	Delivered via the device’s native push channel on iOS and Android. Requires OS-level permission.
Email	Sent to the account email on file. Silenceable-type emails carry a per-type unsubscribe link and a “switch to immediate” link if you’re on a digest. Always-on emails carry a “manage preferences” link only.

Always-on tiers

Twelve notification types are always sent on at least the email channel. They split into two tiers based on why:

Compliance (3 types)

advance_notice_issued: Direct Debit collection scheduled
debit_failed: Direct Debit collection rejected
mandate_cancelled: Direct Debit mandate cancelled

Channel rules: email always sent (cannot be turned off). Push always sent (cannot be turned off), subject only to your OS-level push permission.

For advance_notice_issued specifically, the email itself is sent by the payment processor (Stripe) directly, as the Direct Debit scheme requires. Syndik8 sends the in-app record and the phone alert for that one.

Lawful basis: Direct Debit Guarantee scheme requires the bank holder to be notified.

Critical (9 types)

payment_verification_complete / payment_account_restricted / payment_charges_enabled / payment_person_failed: payment account state changes (admin-facing)
cash_call_due_soon / cash_call_overdue: money you owe the syndicate
vote_closing_soon: a vote you can participate in is closing within 24 hours
tacho_continuity_detected: submitted usage data has an inconsistency that affects billing
platform_fee_change: the platform fee rate for a syndicate has changed (admin-facing)

Channel rules: email always sent (cannot be turned off). Push is on by default and can be turned off via the single aggregate switch on the Critical row in the Important section, this applies to all 9 types together. Turning the switch off shows a confirmation dialog first; turning it on never prompts.

Lawful basis: contractual necessity (the syndicate management service members have signed up for). The distinction from Compliance: highly recommended, but not legally required.

Behaviour rules

The notification centre is always on. You cannot disable it. It is the source of truth for what you have been notified about.
The notification centre also offers per-type mute actions. On mobile, swipe the tile to reveal mute-push and mute-email actions (alongside delete); on web, use the hover-reveal menu; either way, long-press works as an accessible equivalent. Always-on types show a padlock on those actions and cannot be muted from here either, matching the preferences screen.
Push is mobile-only. The web version does not support push notifications. Toggles for push are hidden on the web everywhere on the screen.
Push depends on OS permission. If you have denied push permission in iOS or Android settings, every Push toggle on the screen stays visible but is disabled; turning them on has no effect until you grant the OS permission. When permission transitions from denied to authorised, the app offers to bulk-enable push across categories, including the Critical group.
Email goes to the account email set on your profile. There is one email address per account; notifications are not sent to multiple addresses.
Always-on types ignore digest mode. Even if you are on a weekly digest, Compliance and Critical emails arrive as they happen.
How a digest run picks up notifications. Each run collects everything pending since the last digest that was successfully delivered to you. For your first-ever digest there is no prior successful run to measure from, so the look-back is a fixed window: 36 hours for daily, 8 days for weekly, 35 days for monthly. If a run fails to send, nothing is lost, the next scheduled run picks up where the last successful one left off. Notifications you have already read in-app before the run fires are not included. A digest email shows at most 50 items, with a “+N more” link to the notification centre for the rest.
Unsubscribing from email uses the per-type unsubscribe link at the bottom of each silenceable-type email, or the preferences screen. Unsubscribing from one type does not affect others. Always-on emails do not carry an unsubscribe link.
Switch back to immediate. Digest emails carry a one-click link to revert to immediate delivery. It only changes the digest cadence; it does not unsubscribe you from anything.
Turning the digest off simply stops any pending items from being emailed as a batch; it does not send them immediately or clear them, they remain visible in the notification centre.
The Email Digest card shows a “Last delivered” line once a digest has gone out at least once, so you can see the pipeline is working.
Admin-only notifications are filtered out of the notification centre and the preferences screen for members who do not hold an admin role anywhere.
Preferences are per-user, not per-syndicate. If you belong to more than one syndicate, your preferences apply everywhere.
A single notification can go out on multiple channels. An urgent booking rejection, for example, will land in the notification centre, fire a push if push is enabled, and send an email if email is enabled, all driven from the one server-side event.
