How do I perform an IP/domain warmup?

Warmup execution process:

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.
