Email Queue Management: Why It Makes or Breaks Your Sender Reputation

Your email queue is your reputation. Poor queue management = blocked emails.

Queue Depth Matters
Sending too fast overwhelms receiving servers. PostMTA's rate limiter throttles based on ISP-specific limits.

Retry Logic
Soft bounces need intelligent retry. PostMTA uses exponential backoff with ISP-specific timing.

Queue Priority
Not all email is equal. Transactional emails get priority over marketing during congestion.

Stuck Queue Recovery
When servers go down, PostMTA automatically throttles and recovers without manual intervention.
