us-east-1 is back online and all sending is healthy.

Thank you for your patience during this. We will be following internally and with AWS about ways we can avoid this in the future.

We are continuing to discuss with AWS support.

We changed the default region for free accounts to be eu-west-1.

We are continuing to talk with AWS support but us-east-1 is still offline.

In the meantime, we are investigating alliterative options to get us-east-1 back online.

As a workaround, users can create a domain in a new region besides us-east-1.

We are working on unblocking free users from the single-region limitation.

We were just notified that sending on our us-east-1 region on AWS was shutdown without any warning. This has halted all sending in this region. We are engaging with our account team to unblock this immediately.
