Delay in Email delivery

We are currently experiencing email delivery delays to Outlook and Gmail domains. The issue appears to be on the Outlook and Gmail side and is not related to Brevo.

Outlook Status: <https://status.cloud.microsoft/m365/referrer=serviceStatusRedirect>

We are actively working on mitigating the impact and will share further updates as they become available.

We have mitigated the impact on gmail domain delivery and are seeing a reduction in delay. We continue to monitor our systems closely to ensure stability.

Outlook still seem to be impacted.

We’ll provide an update once we confirm the issue is fully resolved.

We are closely monitoring the Outlook status page for updates on the incident. Microsoft has confirmed continued recovery across affected regions, with improvements observed in North America and Europe, and encouraging recovery signals in Asia-Pacific. However, some users may still experience intermittent issues or email delivery delays as mitigation continues.

Email delivery to other domains remains unaffected on our side. We are actively monitoring the service on our side and will share further updates as needed.

We are seeing some improvement in email delivery rates to Outlook. We will continue monitoring the situation to ensure stability.

Email delivery rates to Outlook are improving and have now stabilised. Upon further investigation, we identified that the Gmail delays were not caused by an issue on Gmail’s side. Instead, the backlog of pending Outlook messages increased the processing pressure on our infrastructure, impacting Gmail delivery as well.

We have mitigated this issue. While some delays to Outlook may persist due to the ongoing Microsoft outage and its reduced acceptance rate, we expect email delivery across other domains to return to normal.

Thank you so much for your patience.
