🔥 Why Is IP Warmup Important?
If you’re using a new or dedicated IP for email sending, you can’t send thousands of emails at once. 🚀 Email providers monitor your IP’s reputation, and sudden bulk sending can land you in spam.
✔️ What IP Warmup Does:
✅ Improves email deliverability 📩
✅ Reduces the risk of blacklisting 🚫
✅ Builds a strong sender reputation 🏆
✅ Helps emails land in the inbox instead of spam 📬
🔹 How Does IP Warmup Work?
IP warmup is a gradual process where you slowly increase the volume of emails sent from your IP. This helps email providers trust your sending habits.
✅ Best Strategy to Warm Up Your IP Address
📅 Week-by-Week IP Warmup Plan
Follow this structured warmup schedule:
| 📅 Week | 🔢 Emails Per Day | 📧 Total Emails Per Week |
|---|---|---|
| Week 1 | 100 – 500 | 3,500 |
| Week 2 | 1,000 | 7,000 |
| Week 3 | 2,000 – 3,000 | 15,000 |

🔹 Step-by-Step Guide to Warming Up an IP Address
🛠️ Step 1: Set Up Proper Authentication
Before sending emails, configure these essential authentication records:
✅ SPF (Sender Policy Framework) – Prevents spoofing
✅ DKIM (DomainKeys Identified Mail) – Verifies email authenticity
✅ DMARC (Domain-based Message Authentication) – Adds protection
🛠️ Step 2: Use a High-Quality Email List
Never send emails to random or purchased lists ❌. It will damage your IP reputation.
✅ Best Practices:
✔️ Send to engaged subscribers first
✔️ Remove inactive or bounced emails
✔️ Use double opt-in to verify new subscribers
🛠️ Step 3: Start with Engaged Users
Start by sending emails to your most engaged users – those who have:
✔️ Opened previous emails 📬
✔️ Clicked links 🔗
✔️ Replied or interacted 📩
This signals email providers that your emails are valuable.
🛠️ Step 4: Monitor Your Email Metrics
Track these key metrics to ensure a successful warmup process:
📊 Email Metrics to Watch:
✔️ Open Rate – Should be above 20%
✔️ Bounce Rate – Keep it below 2%
✔️ Spam Complaints – Keep it below 0.1%
