Sep 22, 2026 - 15:58 UTC
Update - We are continuing to investigate this issue.
Sep 22, 2026 - 10:15 UTC
Investigating - Exclaimer engineers are investigating a delivery delay affecting some messages sent from Gmail/Google Workspace to Exclaimer Cloud. Some of these messages may be retried by the sender and may appear as temporary deferrals rather than delivery failures. We are not currently aware of any confirmed message loss and will provide updates as we learn more.
Sep 22, 2026 - 10:08 UTC
Identified - Exclaimer has identified that a small subset of messages (~0.02%) are delayed when routed through Exclaimer due to a suspected issue within Microsoft's servers. This has been raised with Microsoft to investigate alongside Exclaimer Engineers.
Sent messages will be received with a signature applied, as expected.

If you are seeing issues with message deliverability, please reach out to our support team, who will be happy to assist.

Resolved - Email signature delivery is operating normally in the US again after mitigation by engineers. Between 14:20 and 14:54 UTC, customers may have experienced some minor delays whilst imprinting was retried internally and a small number of messages may have been delivered without a signature applied.

We apologise for any disruption caused.
