What happens when the wrong list is uploaded?

Possible scenarios:

• Sent to unsubscribed users (complaints, legal issues)
• Sent to old, stale list (bounces, traps)
• Sent to wrong company's list (confusion, complaints)
• Sent to test list in production (embarrassment)

Immediate effects:

• Complaint spike
• Bounce rate spike
• Potential spam trap hits
• Recipient confusion and anger

Response:

• Stop any remaining sends immediately
• Assess damage (how many sent)
• Prepare communication/apology if needed
• Document what happened

Prevention:

• Verification steps before upload
• Test segment before full send
• Clear file naming conventions
• Loading the wrong cargo onto the ship causes problems at every destination.
