Monitoring
Beginning at approximately 2019-05-17 1300 UTC, customer email campaigns and messages either sent from, or containing references to urls containing "intercom-mail.com", are appearing with a banner in Gmail indicating "This message seems dangerous". This is currently affecting all email sent to Google hosted email accounts.
We understand the root cause of this to be related to customer files sent via Intercom being flagged as malicious by Google. We have removed references to these files and are now monitoring for resolution. At this time we have no ETA on resolution, but we are closely monitoring the situation. We will update this Status Page event as soon as the event is resolved.
