Four questions answered in this document: (1) Which notification triggers exist, and for whom? (2) Which actions send a push notification vs. an email — or both? (3) How do notifications relate to the activity feed and the daily digest? (4) What is currently live in production vs. still to be built?

A fifth section covers all email types, their triggers, and a translations inventory (currently a placeholder — to be completed after repository access is granted). A sixth section presents our proposed improvements, for discussion.

1 The two notification systems

HearPeers currently runs two parallel notification systems. They are independent — an event can trigger one without the other.

System What it does Where users see it
In-platform notifications Alerts that appear inside the platform Bell icon (top navigation) + notification count badge
Email notifications Emails sent to the user's inbox User's email address
User control: Users can control their email notification preferences in Account Settings. In-platform notifications cannot currently be turned off individually.

2 Notification triggers — what exists today

Social actions

What happens Who gets notified In-platform bell Email sent
Someone likes your post Post author Yes No
Someone comments on your post Post author Yes Yes
Someone replies to a comment Comment author Yes Yes
You @mention someone in a post or comment Mentioned user Yes Yes
You save a post No one No No

Connection actions

What happens Who gets notified In-platform bell Email sent
You receive a connection request Recipient Yes Yes
Your connection request is accepted Requester Yes Yes
Your connection request is rejected No one No No
You cancel a connection request No one No No

Group actions

What happens Who gets notified In-platform bell Email sent
You are invited to a group Invited user Yes Yes
Someone requests to join your group Group admin Yes Yes
Your membership request is approved or rejected Requester Yes Yes
Group details are updated All group members Yes Yes
A backend admin adds a user to a group All group members ⚠️ Yes No
You are promoted to group admin Promoted user Yes Yes
⚠️ Known issue: When an admin adds a user to a group via the backend (not through the community interface), all existing group members receive a bell notification — not just the newly added user. This creates unnecessary noise. See Section 5 for the proposed fix.

Direct messages

What happens Who gets notified In-platform bell Email sent
You receive a direct message Recipient Yes Yes

System / account emails

These emails are transactional — they are always sent and cannot be turned off by users.

What happens Who receives it Email sent
Account created New user Yes (welcome email)
Invitation to join the platform Invited user Yes
Password reset requested User Yes
Password reset completed User Yes
Profile verification User Yes
Note: These emails live in a separate code path from the notification system. They are not controlled by the notification preferences in Account Settings.

3 Notifications, the feed, and the daily digest

The activity feed

The activity feed (home page) is separate from notifications. It shows a stream of community activity — posts, joins, profile updates — but does not generate notifications. Users discover this content by visiting the feed; nothing is pushed to them for feed activity.

How they relate

What triggers it Feed Bell Email
Post or comment by someone you follow Yes No No
Someone likes your post No Yes No
Someone comments on your post No Yes Yes
Group update No Yes Yes
New direct message No Yes Yes
New connection request No Yes Yes

The daily digest not yet built

The daily digest is a proposed feature (FR-24) — a single daily email summarizing all low-urgency notifications from the past 24 hours, sent at 08:00. It does not exist in production today. Details in Section 6.

4 What is in production vs. what is pending

Currently live in production live

Known issues in production issues

Issue Impact Priority
Notification badge shows "100" instead of the real unread count Users cannot tell how many notifications they actually have High
"Mark all as read" button does not work — count does not reset Badge stays at 100 even after visiting notifications High
Backend admin adding a user to a group notifies all members, not just the new user Notification noise for all group members Medium
Post likes generate a bell notification but no email (no preference toggle available) Consistent — likely intentional, but not formally confirmed Low

Not yet built pending

6 Proposed strategy

The following section presents our recommendation for how notifications should work going forward. This is a proposal for discussion — nothing here is final until agreed with MED-EL.

The problem with the current approach

Today, the platform treats all notifications the same. Any event that can send an email does so immediately, and users cannot distinguish urgent from non-urgent. This leads to two failure modes:

Proposed: two-track delivery model

We propose organizing all notifications into two tracks based on urgency.

Instant

Events that require prompt attention — where a delay would break the user's workflow or leave someone waiting.

Event Who receives it Rationale
New direct message Recipient Personal and time-sensitive
New connection request Mentor / Area Manager recipients A Candidate is waiting for support
First comment on your post Post author Primary social feedback signal
@mention in post or comment Mentioned user Direct address — requires response
Promoted to group admin Promoted user Role change — should be immediate
Daily digest

Events that are informational or low-urgency — where batching reduces noise without missing anything important.

Event Who receives it Rationale
Connection request (Candidate recipient) Recipient Lower volume; no immediate action needed
Connection request accepted Requester Confirmatory; no action required
Group membership request (to admin) Group admin Admin task; daily cadence is sufficient
Membership request approved/rejected Requester Confirmatory
Group invite Invited user Discovery; not time-sensitive
Group details updated Group members Informational; currently high volume
Subsequent comments on a post (2nd and beyond) Post author Batched as "N people commented on your post"
Bell only

Not sent by email — in-platform notifications only.

Event Rationale
Post likes High volume, low urgency
Profile updates by others Activity feed is sufficient
Group joins/creates by others Activity feed is sufficient

Before and after, by role

The matrix below shows every notification event and how its delivery changes for each role. Today, there is no digest — everything that sends an email does so instantly. The proposed model introduces the digest track and redirects low-urgency events into it.

Candidate Candidate / Caregiver

Self-registered user — newly diagnosed, candidate for implant, or caregiver. Low-volume user profile.
Event Today Proposed Change?
New direct message Instant Instant No change
@mention in post or comment Instant Instant No change
First comment on your post Instant Instant No change
Subsequent comments on your post Instant (each) Digest (batched) Reduced
Connection request received Instant Digest Reduced
Connection request accepted Instant Digest Reduced
Group invite Instant Digest Reduced
Group details updated Instant Digest Reduced
Membership request approved/rejected Instant Digest Reduced
Post like received Bell only Bell only No change
Welcome / system emails Instant Instant No change
Candidates are low-volume users. The main gain is tidying up group noise and batching secondary comments.

Recipient Recipient

Confirmed cochlear implant recipient. Moderate volume user.
Event Today Proposed Change?
New direct message Instant Instant No change
@mention in post or comment Instant Instant No change
First comment on your post Instant Instant No change
Subsequent comments on your post Instant (each) Digest (batched) Reduced
Connection request received Instant Digest Reduced
Connection request accepted Instant Digest Reduced
Group invite Instant Digest Reduced
Group details updated Instant Digest Reduced
Membership request approved/rejected Instant Digest Reduced
Post like received Bell only Bell only No change
Welcome / system emails Instant Instant No change
Similar to Candidates. Moderate volume; the digest reduces email frequency without losing anything urgent.

Mentor Mentor

Trained volunteer mentor. High-volume user with group responsibilities.
Event Today Proposed Change?
New direct message Instant Instant No change
@mention in post or comment Instant Instant No change
First comment on your post Instant Instant No change
Subsequent comments on your post Instant (each) Digest (batched) Reduced
Connection request from a Candidate Instant Instant Preserved ★
Connection request from a Recipient Instant Digest Reduced
Connection request accepted Instant Digest Reduced
Group invite Instant Digest Reduced
Group details updated Instant Digest Reduced
Membership request approved/rejected Instant Digest Reduced
Post like received Bell only Bell only No change
Welcome / system emails Instant Instant No change
This is where the most value is. Mentors currently receive instant emails for every group update — high volume that leads them to disable notifications entirely. The proposed model keeps the one event that matters most (a Candidate reaching out) instant, and moves everything else to the digest. Mentors stay reachable without being overwhelmed.

Area Manager Area Manager

Regional manager — oversees users and groups within an area. Highest individual notification volume.
Event Today Proposed Change?
New direct message Instant Instant No change
@mention in post or comment Instant Instant No change
First comment on your post Instant Instant No change
Subsequent comments on your post Instant (each) Digest (batched) Reduced
Connection request received Instant Digest Reduced
Connection request accepted Instant Digest Reduced
Group membership request (admin action required) Instant Digest Reduced
Membership request approved/rejected Instant Digest Reduced
Group invite Instant Digest Reduced
Group details updated Instant Digest Reduced
Promoted to group admin Instant Instant No change
Post like received Bell only Bell only No change
Welcome / system emails Instant Instant No change
Highest volume role. Area Managers manage multiple groups and currently receive an instant email for every group update across all of them. The digest consolidates all group activity into one daily summary — the single biggest noise reduction in the whole proposal.

Super Admin Super Admin / MED-EL Backend Users

Highest-privilege community governance role. Not currently differentiated in the notification system.
Event Today Proposed Change?
All notification events Same as other roles To be defined by MED-EL To be agreed
Super Admins are not currently differentiated from other roles in the notification system. We recommend MED-EL define their notification needs separately — they may want no email notifications at all, or a different digest cadence.

What needs to be built

Item What it is Status
Fix notification badge (real count, reset on visit) Frontend fix Not built
Fix "mark all as read" Frontend + backend fix Not built
Fix backend group additions (notify added user only) Backend fix Not built
Daily digest queue Backend — new queue for batched events Not built
Daily digest cron job Backend — daily sweep, sends one email per user Not built
Daily digest email template Email — one summary template with conditional sections Not built
Digest preference toggle in Account Settings Frontend + backend Not built

One open research question

Why did you turn off email notifications?

This question confirms whether frequency is the problem (in which case the digest solves it) or whether the issue is content irrelevance or platform distrust (which require different solutions). This research should run before development begins on FR-24.
