Our team continues to work closely with our email provider to fully resolve the remaining intermittent delivery failures. While we've seen continued improvement in delivery rates since yesterday, we're not yet at the full resolution.

We'll continue our close monitoring throughout the day and will share updates as we have more information.
Thank you for your continued patience as we work to get this fully resolved.

We're continuing to monitor email deliverability to Yahoo-based addresses. While some messages are now being delivered successfully, intermittent failures are still occurring.

We're actively working with our email provider to confirm full recovery and understand the remaining delays. These types of issues can take some time to fully stabilize, which is consistent with similar situations we've seen in the past.

We'll continue to monitor closely and will share another update in the morning. Thank you for your understanding while we get this fully resolved.
