IP Warming
IP warming is the process of gradually increasing send volume from a new sending IP so inbox providers learn to trust it — preventing the cold-IP spam-folder hit.
What is IP warming?
IP warming is the process of slowly ramping email send volume from a new IP address so that inbox providers (Gmail, Outlook, Yahoo) build a positive reputation history before you send at full volume. Send too much too fast from a fresh IP and you'll land in the spam folder fast.
Why it matters
- Inbox providers track per-IP reputation; new IPs default to low trust
- Going from 0 to 10,000 sends/day overnight nearly guarantees deliverability damage
- Recovery takes weeks; warming takes days when done right
A safe IP warm-up curve
- Day 1: ~50 sends
- Days 2–14: roughly double per day, ramping to 5,000–10,000
- Stay below your target volume until engagement metrics confirm strong reputation
- Send only to your most engaged segment during warm-up
Shared vs. dedicated IP
- Shared: lower risk for low volume, but you inherit pool-mate reputation
- Dedicated: worth it once you hit consistent ~50K+ sends/month; full control of reputation
How TexAu helps
Use TexAu to identify and prioritize your most engaged segment for warm-up sends — high-engagement audiences produce the positive signals (opens, replies) that mailbox providers use to build IP trust quickly.
