Consider scheduling sending at off-peak times
If you have the flexibility, schedule email for off-peak times. Most senders schedule email batches for the top of the hour or half hour. Scheduling email to avoid those times (for example, scheduling at 10:53) can result in lower deferral rates because it won't be going through our servers at the same times as everyone else's mail.
