Pro Tip: Start slow and warm up your IPs before sending at high volumes. This is a per-campaign setting, and you can schedule multiple campaigns simultaneously.

Warming up IPs works best if you have less than 1% hard bounces. Any hard bounce rate greater than 1% can still harm your IP reputation. We offer an automated warmup system for lower volume senders, and recommend a manual warmup process for larger senders.

Sample warmup schedule for a 10 million email account:

DayVolume
Day 11,000
Day 22,000
Day 33,000
Day 45,000
Day 58,000
Day 615,000
