Mailbox — email outbox and delivery log

Who can do this

Any team member with access to the Mailbox section in the main navigation. Requires an active company account on the Team plan and above.

What the Mailbox shows

Path: Mailbox in the left navigation.

The Mailbox displays all outgoing emails sent through Uku for the selected company. Each row shows:

From — the sender name
To — the recipient name
Client — the client associated with the email
Subject — the email subject line
Sent at — date and time sent, in your company’s timezone
Status — delivery status (see below)
Info — additional details or error message

Click any row to open the full email detail dialog. From there you can read the email content and, if the email is linked to a task, click Open related task to jump directly to it.

Email delivery statuses

Sent — delivered successfully.
Failed — could not be delivered. The Info column shows the reason. When you open a failed email, a red banner displays “Email not delivered” with error details.
Warning — sent, but Uku had to fall back to the default Uku email address instead of your custom sender address. The detail dialog shows “Sent, but fallback to Uku email.”

Filtering and searching

Date range — quick presets: Today, Yesterday, This week, Last week, This month, Last month, Last 3 months. The date range goes back up to 100 days.
Company — if you belong to multiple companies, select which company’s outbox to view.
Client — filter by one or more clients.
Status — filter by All, Sent, Failed, or Warning.

Save your current filter combination as a bookmark to quickly return to the same view later.

How to resend failed emails

Use the Status filter and select Failed.
Select the emails you want to resend by clicking the checkboxes on the left side of each row.
A bulk action bar appears showing how many emails are selected.
Click Send failed emails in the bulk action bar.
A confirmation dialog shows how many failed emails will be resent. Click Send all to confirm.

After resending, the table reloads automatically. Only emails with a Failed status can be resent — if you select a mix of sent and failed emails, only the failed ones are included in the resend action.

Tips

Check Mailbox regularly if you use custom sender email addresses — the Warning status can indicate configuration issues with your email setup.
Use the date range presets (Today, This week, etc.) to quickly review recent activity.
Click any row to read the full email content and troubleshoot delivery using the error message in the detail view.
