How to warm up an IP address

Why do you need to warm up your IP address?

Internet Service Providers use your IP address to identify you as a sender, track your sending behavior, and give you a reputation score. The greater the score, the higher the delivery rates. Warming up an IP address means sending low volumes of email on your dedicated IP and then systematically increasing your email volume over some time. During the warmup, ISPs evaluate your sending behavior. The more engagement you receive during the warmup period, the better the ISPs will favor your IP. 

How to ensure IP address warming is successful?

IP address warming tips:

Be consistent

It is important to slowly increase your email send volume. A sudden increase in the sending volume or large gaps between the sending can damage the sender’s reputation.

Target active users

Open rates are another important metric count while warming your IP’s address. So, initiate by targeting active users. 

Check bounce and complaint rates

As you gradually increase your volume, keep analyzing your bounce and blocked rates after each campaign. It is crucial to monitor for negative output. Moving with bounces and blocks could permanently damage your sender’s reputation. 

How to Warm Up IP in Email Marketing

• First, choose a segment of the email list to warm up. ISPs suggest starting with your personal Gmail accounts. This is crucial if you are building an entirely new reputation or trying to improve one that isn’t performing very well. Some emails will probably be in the SPAM folder. Pick the emails out of SPAM and put them into your contacts/safe sender lists. That’s why you start with your emails. 
•  Start sending to your contact list. And choose recipients and mail streams who are engaged. You can use welcome email as your trail mail for your new IP. 

If the new IP is not performing well (fewer open rates, more blocks), be patient and consider slowing your volume, allowing your reputation to catch up.
