Delayed email delivery to Gmail recipients

This incident has been resolved.

We identified an issue affecting email delivery to some Gmail recipients. A recent update to our email sending configuration resulted in temporary rate limiting by Gmail for messages sent from our domain. We are actively working with our email provider to restore normal delivery performance and gradually rebuild sender reputation.
Emails are continuing to retry automatically, and while some messages may experience delays, most are expected to be delivered successfully.

We are investigating delayed emails sent to Gmail and Google Workspace addresses. Other recipients (Outlook, custom domains, etc.) are not affected. We'll share an update as soon as we have more information.
