IP Warm-up Definition
IP warming is a process in which the volume of emails is progressively increased over the course of several days to build a good reputation for the IP with email providers.
IP Warm-up Schedule
- Weeks 1-2, send to your most active subscribers (Positive engagement in the past 30 days).
- Weeks 3-4, expand to moderately active subscribers (Positive engagement in past 60 days).
- No further contact with subscribers who haven’t shown any engagement in the past 90 days, during the first 6 weeks of the warm-up schedule.
- If the warm-up limit goes above 10 million, we suggest adding another IP.

What to Expect?
Bulking at Yahoo!, AOL, Gmail will clear with a few sends with positive metrics. Though it can take up some time to get in the inbox, what’s important is to constantly maintain contact with engaged subscribers.
Delays at AOL, Microsoft, Comcast will retry for 72 hours and if failed will be registered as a 421 error in the record. Delays are normal as long as they are delivered to the inbox in the end and will lessen with increasing reputation. If Timeouts persist in large quantities, then you should reduce your engagement volume for the particular email provider.
Most commonly blocks occur when the list isn’t engaged enough. You need to segment your list carefully so that you receive maximum engagement.
Monitor your metrics carefully during the warm-up period to extract maximum value.
