It is not possible to login to Campaign Monitor at this time, our team are aware of the cause and are working to have this sorted as soon as possible.

Update

Our engineering team continues to investigate the issue and is working to resolve it as quickly as possible. While the application is currently unavailable, this does not affect emails that have already been sent — links and images within those emails will continue to work as expected.

Update

2026-07-16T12:02:00.0000000Z

Our team has resolved the issue, and the application is now operating as normal.

We will continue to monitor the situation closely and will update the status page with any further information.

Resolved

2026-07-16T12:16:00.0000000Z

The application is now working normally and customers can now login without any issues.

Any campaigns scheduled to send during the period the application was unavailable will now send.

Unfortunately, Transactional emails that were triggered during this period won't have been sent and will need to be re-triggered.
