Issue Summary

• Email server is working (we receive user creation and @mention emails).

• When a ticket/work package is assigned to a user by an admin, no email notification is received by the assignee. Portal (in-app) notifications work, but no corresponding email is sent.

• This issue persists even though all relevant notification and aggregation settings are correctly configured.

Settings Verified

(Screenshots attached to this email for reference)

1. Aggregation: Set to 0 minutes — so notifications are sent immediately, not batched.

2. Email Reminders: Immediate email for @mentions and personal reminders.

3. Notification Settings:

   • Global: Notified for all participating actions — Mentioned, Watcher, Assignee, Accountable, Shared.

   • Project-specific: “Assignee” (as well as other participating) notifications are enabled.

   • Non-participating categories are not enabled (as expected).

4. @mentions emails work, confirming SMTP and outbound emailing aren’t the problem.

5. Issue is reproducible: Assign user A to a work package by user B. No email is received by user A, but an in-app notification appears.

Steps to Reproduce

1. Ensure user has all notifications enabled for participating actions (see screenshots).

2. Admin assigns a ticket/work package to the user.

3. User does not receive an email, but does get an in-app alert.

4. @mention notifications still send emails as expected.

What We Expect

• As per documentation, when a user is assigned to a work package by another user (not a self-assignment), an email should be generated and sent to the assignee.

Environment

• OpenProject version: 13.21

• Email delivery: Working for other cases

• OS: Ubuntu 22.04

• Apache 2, HTTPS enabled

Attachments

• Aggregation settings

• Email reminders settings: even email reminders enabled still I am not getting mai

• Notification preferences global

• Notification preferences project-specific

Can you help investigate or confirm if this is a known issue or provide a workaround?

Thank you!

Hello Malyadri,

immediate e-mail notifications do not automatically get sent out when someone becomes assignee of a work package. Users can handle this in der own settings for e-mail notifications. There, they can select that they receive an immediate e-mail reminder, when someone @ - mentions them or when they set a personal reminder. [1] They can also de-select these options and would then receive no immediate reminders at all.

All other in-app notifications (e.g. assignee, date alters..) are aggregated and included in a scheduled e-mail reminder which will be send out at a specific time (scheduled by user, see -> [1]). Note: Only unread in-app notifications are inculded in the e-mail reminder.

Tip:

You can set more than just one e-mail reminder per day via the personal email reminders settings. For example, you could let OpenProject send you a reminder (=summary) for all unread in-app notifications each hour of your work day. (See guide -> [1]).

Best,

Alexander
