IP Warming: Taming the Wild West of Email Delivery

Once you are ready to start mailing from a new IP, there is one thing that can make or break your email deliverability, and that, my friends, is IP warming. This means gradually increasing the volume of emails you send from your new IP to build a good sender reputation. If done right, this will make emails land in inboxes instead of spam folders.

This blog post explores how you can do it naturally and effectively. Keep reading!

What is IP Warming, Exactly?

Think of it as moving into a new neighborhood: the neighbors—postbox providers like Gmail, Yahoo, etc.—do not know you, and you must ease them into trusting you by sending a small volume of emails first and gradually increasing that number. 

This way, your IP develops a good reputation, and the providers learn they can trust you since you send wanted, legitimate emails.

Why is IP Warming So Important?

IP warming matters big time because:

• It helps you avoid being flagged as spam, because when a new IP address suddenly starts sending a high volume of emails, it can trigger spam filters.
• The gradual increase in volume establishes a good reputation with email providers and improves deliverability.
• Email marketing is highly effective when your sender reputation is protected.

What are IP Warming Best Practices?

So, how do you get the ol’ good sender reputation? Here’s how:

1. Start Small, Slow, and Steady

At first, send only a few emails a day. A general rule of thumb is to begin with approximately 500 emails per day, per mailbox provider (like Gmail or Outlook), and increase volume over several weeks.

Why start small? You want to show mailbox providers that your recipients are engaging with your emails—opening them, reading them, clicking on them, etc.—which is a signal that your emails are valuable and relevant.

2. Target Engaged Recipients First

When you start warming up your IP, you’ll want to focus on sending to your most engaged recipients—those who frequently open and interact with your emails. These recipients are more likely to open and click, establishing a positive sending pattern for mailbox providers.

Avoid sending to unengaged or old lists at this stage. If a lot of your emails are ignored or bounce, it could hurt your IP’s reputation before you even get started.

3. Gradually Increase Volume

Once you’ve successfully sent emails to your most engaged users, start increasing your sending volume. A typical schedule might look something like this:

• Day 1: 500 emails
• Day 2: 1,000 emails
• Day 3: 2,000 emails

Keep doubling your volume over time. But remember, don’t go too fast—gradual increases over about two to three weeks work best. Rushing this process can trigger red flags for mailbox providers.

4. Monitor Engagement and Adjust Accordingly

Throughout this IP warming process, keep a close eye on how recipients are engaging with your emails. Watch open rates, click-through rates, and bounce rates. 

If you see any sharp declines in engagement or any spikes in bounces, take a step back, reduce your volume, and determine why it’s happening. Perhaps something is wrong with your email content, your subject lines, or the list you’re mailing to.

5. Use Authentication Protocols

The most important thing to do before you ever send emails from your new IP: set up email authentication. This includes SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance). 

These will basically verify that you really are the sender of those emails and will protect your sender reputation.

How Long Does IP Warming Take?

Warming up an IP does not happen overnight. It usually takes two to four weeks, depending on how much email you are going to send. Large volumes of email take longer. Rush it, and poor deliverability will be the outcome—so patience is a virtue!

To wrap up, warming up your IP is like building a relationship—trust takes time. Take it slow, monitor your progress, and soon enough, your emails will land confidently in inboxes instead of getting lost in spam!
