MONITORING 21 days ago - at 09/24/2025 09:28AM

Email sending via the Email Classic WebApp has been re-enabled for the EU region. Sending from the WebApp should now work again as expected.

Please note: There is an automatic retry mechanism in place that will attempt to resend any emails that originally failed within the last 800 minutes. If an email was queued for sending more than 800 minutes ago, it will not be resent automatically and needs to be sent again.

We will continue to monitor the situation to ensure everything remains stable.

If you have any questions, please contact our support at support@staffbase.com.

We have identified the cause of the issue preventing emails and test emails from being sent via the WebApp in Email Classic on the German system.
Email sending is currently blocked due to a restriction from our external email provider. We’ve already reached out to their support and provided the necessary information. We’re now waiting for them to review our case and restore email sending.

We will continue to share updates as soon as we receive more information.
