How do I perform an IP/domain warmup?

Preparation:

• Segment list by engagement (most engaged first)
• Ensure authentication is perfect
• Set up monitoring

Starting volume:

• Begin with 50-500 emails/day depending on total list size
• Send only to most engaged recipients

Gradual increase:

• Increase by 50-100% per day/few days
• Typical schedule: 2-4 weeks to full volume
• Adjust based on metrics

Monitoring:

• Watch bounce rates, complaints, opens daily
• Pause or slow down if issues appear
• Check postmaster tools regularly

Expansion:

• Add progressively less-engaged segments
• Continue monitoring throughout
• Small test shipments, then gradually larger, always monitoring reception.
