Spam outbreaks are the sudden bursts of spam that flood inboxes, causing help desk calls and overloaded servers. The outbreaks occur because spammers use unknown senders, targeted attacks and new campaigns.
- Unknown senders cannot be blocked because they don't have a reputation
- Targeted attacks avoid global anti-spam visibility, avoiding detection in spam traps
- New campaigns present previously unseen content
It takes time and massive visibility to see new campaigns, develop protection and turn the unknown into known spam senders. Even the best anti-spam labs take 1 to 2 minutes to update their protections. Outbreaks are successful because spammers have an open window of opportunity.
Delaying email with Traffic Control - even just two minutes - gives spam filters valuable time to respond, improving capture rates.
