Safe IP Warm-Up Plan for New Sending IPs (30-Day Schedule)
Warming up a new dedicated IP builds trust with mailbox providers. Always send to engaged, opt-in recipients and keep complaint rates near zero.
Principles
- Start small and double gradually.
- Send only to recently active subscribers (opens/clicks in last 30–60 days).
- Remove hard bounces immediately and suppress chronic soft bounces.
Example Schedule
| Day | Max Volume |
|---|---|
| 1 | 50–100 |
| 2 | 100–200 |
| 3 | 200–400 |
| 4 | 400–800 |
| 5 | 800–1,200 |
| 6–7 | 2,000 |
| 8–10 | 3,000–5,000 |
| 11–14 | 7,500–10,000 |
| 15–21 | 15,000–25,000 |
| 22–30 | Scale based on engagement and errors |
Monitoring
- Track bounces, blocks, and spam complaints daily.
- Use separate subdomains for transactional vs. marketing mail.
- Pause or reduce volume if soft bounces rise or engagement drops.
Compliance Reminder
Send only to explicit, opt-in lists. Include a functional unsubscribe link, physical address, and clear sender identity.
