This incident has been resolved.

We are now back to a real time sending on Send API 3.0, the issue is resolved. We are still monitoring the platform to be sure everything is now going smoothly.

We have been experiencing a delay on the delivery of some emails sent through Send API 3.0 since 14:00 UTC. Our technical team is already hard at work to resolve this issue, and no email has been lost, only delayed.
We will update this page as soon as we have more information.
