Should I use randomization in sending times?

• Randomization in sending times helps avoid the predictable patterns that spam filters detect.
• What to randomize:
• Inter-message delays: Add random variation between sends (e.g., 1 to 5 minutes instead of exactly 2 minutes)

• Daily start time: Vary when sending begins each day
• Daily volume: Slight variation in total sends per day
• Sending windows: Don't send at exactly the same hours every day

Implementation approaches:

• Most cold email tools have randomization settings
• Configure percentage variations (plus or minus 30%)
• Set business hour windows rather than exact times
• Allow skipped sends occasionally

Limits of randomization:

• Won't save fundamentally bad practices
• Doesn't replace quality content and targeting
• Still detectable at scale with sophisticated analysis
• One signal among many that filters evaluate

• Combined with other practices:
• Randomization plus personalization plus reasonable volume creates natural-looking patterns
• No single technique is sufficient alone
• Quality fundamentals matter more than pattern tricks
