In this guide, I’ll explain the essentials of IP warming and show you how to build your email-sending reputation gradually.

What is IP Warming?

When you send a lot of emails all at once from a new IP address, ISPs might think you’re a spammer.

Therefore, IP warming is the process of slowly increasing the number of emails sent from a dedicated IP address to help build a good reputation with Internet Service Providers (ISPs).

To warm up an IP, send a few emails to your most engaged subscribers and slowly increase the volume over time. This shows ISPs that you are a trustworthy sender and that people want to receive your emails.

Why is IP Warming Important?

When you send emails from a new dedicated or shared IP address, ISPs watch your sending behavior closely. Gradually increasing your sending volume shows ISPs that you are a legitimate sender.

ISPs examine your sending history, engagement rates, and how recipients interact with your emails. A positive reputation means your emails are more likely to be delivered successfully.

Using IP warmup improves your chances of higher engagement rates, as emails that land in the inbox rather than the spam folder are more likely to be opened and read.

If your emails are getting opened and not bouncing back, your IP reputation will improve, ensuring better deliverability in the future.

How to Warm Up an IP Address

Following best practices for the IP warmup process ensures your emails reach your recipients’ inboxes and maintain a good sender reputation. Here are some key strategies to follow:

Step 1: Start with a Clean Email List

Start with a clean email list to avoid sending emails to inactive or invalid addresses. Use email verification tools to remove these addresses, reducing the risk of bounces and spam complaints.

To clean your email list effectively, you can use TruLead by OptinMonster and cultivate a roster of qualified customers and leads.

Step 2: Segment Your Audience

For a new domain, you can start by sending emails to your most engaged subscribers, who are the people who open, click, and buy in the following buckets:

  • Less than 30 days
  • 30-60 days
  • 60-90 days
  • 90-180 days
  • Over 180 days

Slowly include less engaged segments over time to build a positive sending history. Email service providers like Mailchimp and Drip allow users to create different audiences and segments.

Step 3: Create Engaging Content

Create valuable and interesting content for your emails. Personalized content that resonates with your audience can improve engagement rates.

Always include an easy way to unsubscribe to keep your list healthy and avoid anything that may seem like a spam trap.

Step 4: Set Up Authentication Protocols

Ensure that your email domain is authenticated with SPF, DKIM, and DMARC. These protocols help ISPs verify your emails.

They ensure your emails are legitimate and not spoofed, improving your sender’s reputation. Check out this guide to learn more about SPF, DKIM, and DMARC.

Step 5: Gradually Increase Email Volume

Start with a small number of emails and ramp up the volume slowly. This slow build helps ISPs see that you are a legitimate sender.

Avoid sudden spikes in email volume, which can trigger spam filters. Also, ensure you follow a proper IP warmup schedule when sending emails. For instance:

  • During the first two weeks, send emails to subscribers who have engaged with your emails within the last 30 days.
  • In the third to fourth week, start including subscribers who interacted with your emails within the past 60 days.
  • By the fifth to sixth week, you can begin targeting subscribers who have engaged with your emails in the last 90 days.

You can use WP Mail SMTP’s Rate Limiting feature to optimize sending times per minute, hour, day, week, and month.

Step 6: Monitor Key Metrics

Keep an eye on your email performance metrics, such as delivery rates, open rates, and bounce rates. High engagement and low bounce rates indicate that your IP warm-up plan works well.

The Pro Version of WP Mail SMTP provides detailed insights into your email performance and deliverability rates. This guide provides more information on monitoring key metrics.

Considerations for IP Warming Schedules

If you send transactional emails, you don’t need a strict IP warming schedule since you can’t control when these emails are triggered.

For marketing emails, it’s important to follow an IP warming plan. This means slowly increasing your email volume each day on the new IP.

A slower warm-up is better because it allows you to identify and fix any issues early on, which will help with long-term deliverability.

Optimize Email Sending

By enabling the Optimize Email Sending feature in WP Mail SMTP, your emails are queued for asynchronous delivery.

This means users filling out forms, signing up for newsletters, or making purchases will immediately see a confirmation message.

Meanwhile, their emails are prepared and sent in the background, ensuring a smooth online experience.

While emails might be sent a minute or two later, this minor delay can improve page load times for email senders.

Email Rate Limiting

WP Mail SMTP Pro offers a feature called Email Rate Limiting to help with IP warming without exceeding your email server’s limits.

You can set how many emails your site should send in a given time frame, whether it’s per minute, hour, day, week, or month.

When the limit is reached, new emails wait in a queue to be sent later. This smart approach helps you manage email traffic efficiently and avoid extra costs for higher plans.
