How did delivery go overnight?

Quiet night. Nothing needs you.

1.89M emails sent. 97.1% delivered, 1.5% still deferred, 1.4% bounced.

Gmail healthyYahoo healthyOutlook slowNo new listings

The deferrals are Outlook pacing one IP, and they are retrying. Most bounces are full mailboxes. None point at your IPs or domains.

Know the minute a tenant gets listed or starts bouncing.
