IP Warming Tips

Email Volume Management

Starting with a low email volume and gradually increasing it is crucial for effective IP warming. For new IP addresses, begin by sending 50-100 emails per day in the first week. If your delivery rate stays above 90% and spam complaints remain below 0.1%, you can double the volume each week.

Here's a common pattern for scaling:

  • Week 1: 50-100 emails/day
  • Week 2: 200-400 emails/day
  • Week 3: 800-1,600 emails/day
  • Week 4: 3,200-6,400 emails/day

Keep bounce rates under 3%. If performance drops, hold your current volume until metrics improve before increasing again.

Contact List Quality

The quality of your contact list plays a big role in IP warming success. Using a list with engaged and active subscribers helps build a strong sender reputation. Remove contacts that have been inactive for more than six months to maintain a clean list.

Here are some tips for managing list quality:

  • Segment by engagement: Focus on subscribers with open rates above 20%.
  • Verify email addresses: Use tools to weed out invalid or fake addresses.
  • Track hard bounces: Ensure hard bounce rates stay below 2%.

Key Success Metrics

Tracking key performance indicators (KPIs) is essential for monitoring the progress of your IP warming efforts.

Metric Target Range Warning Signs
Inbox Placement >95% Below 90%
Open Rate >15% Below 10%
Spam Complaints <0.1% Above 0.3%
Hard Bounce Rate <2% Above 3%
Delivery Rate >95% Below 92%

If spam complaints exceed 0.1%, reduce your sending volume and clean your list. Wait 48 hours with stable metrics before increasing volume again.

Consistency is key. Avoid sudden spikes or irregular sending schedules, as these can trigger spam filters. To boost engagement, send emails during business hours in the time zone of your target audience.
