Email warm-up is a process that helps your emails get into people’s inboxes instead of their spam folders. Email warm-up helps you achieve reliable inbox placement, especially with new accounts or if you’re sending cold emails.

When you "warm up" an email account, you start by sending a small number of emails. Each day, you slowly increase this number.

This way, email service providers like Gmail or Outlook see that your email account is trustworthy. With time, you’ll build a positive reputation, which helps improve your email deliverability.

How to Use the Warm-Up Process for Your Emails

How to Use the Warm-Up Process for Your Emails

1. Start with Low Volume

When warming up new email account, don’t rush into sending hundreds of emails right away. Begin with a low number—say, 10 to 20 emails a day. Why?

Sending too many emails at once from a new or unused account may make spam filters suspicious, which could send your emails straight to the spam folder.

Start small and gradually increase the number of emails each day to build trust with email service providers like Gmail and Outlook.

2. Focus on Engagement

Getting recipients to open and respond to your emails is crucial. High engagement shows email providers that your emails are valuable and welcomed by recipients.

You can encourage engagement by sending emails that invite a reply or by personalizing your messages. For example, try reaching out to friends or colleagues with a question they can quickly respond to.

The more replies and positive interactions your emails get, the better your sender reputation and email deliverability score.

3. Use a Variety of Recipients

To make your email account appear more natural, send messages to different people rather than the same few. This approach mirrors real email activity, which spam filters look for.

Sending to a diverse group—such as friends, colleagues, or even test accounts—helps build a positive reputation for your email domain.

Over time, email providers will recognize that your account sends genuine, trusted emails, gradually increasing your inbox placement for future messages.

4. Monitor Bounce Rates and Deliverability

When you send emails, some might "bounce" back. This means they didn’t reach the recipient’s inbox, usually because the email address is incorrect or the account is inactive.

Monitoring your bounce rate is important because a high bounce rate of fake emails can hurt your sender reputation and make it harder to reach people’s inboxes.

To keep your deliverability strong and bounce rate low, start by sending emails to trusted contacts who are likely to open and respond. You should also use email warm-up tools that help track your bounce, response rate, and deliverability score over time.


5. Consistency is Key

Consistency means sending emails at a steady pace. Avoid sending too many emails one day and very few the next. Email service providers notice sudden changes, which can look suspicious.

Start with a small number of emails and gradually increase the volume over time. This approach builds a positive reputation for your email account and helps you avoid spam filters.

Think of email warmup like practicing a skill—the more consistent you are, the stronger your sender reputation will be. Stay patient, follow these steps, and you’ll see improvements in your email deliverability.

2 Key Ways to Warm Up Your Email Account

2 Key Ways to Warm Up Your Email Account

Warming up your email account can help improve deliverability, so your emails reach the inbox instead of the spam folder. Let’s look at two ways to do this: manually or automatically.

Manual Warm-Up Emails

With manual warm-up, you control the process yourself. You start by sending just a few emails each day. As time goes on, you gradually increase the number of emails you send. This approach helps build a positive sender reputation, which can prevent your emails from being marked as spam.

For example, start by emailing friends or colleagues. Make sure they reply to your emails. Replies show email providers that your account is genuine. This process takes time and effort but helps your email account appear trustworthy.


Automated Warm-Up Emails

Automated warm-up tools, like Lemwarm or Instantly, make the process easier. These tools send small amounts of emails for you, automatically increasing the volume each day. They also help track key metrics like open rates and inbox placement.

Automated tools interact with other real email accounts, ensuring that your emails get replies and avoid spam filters. This way, your email account gains a positive reputation quickly, saving you time and effort.

Which One is Better?

Both manual and automated warm-up methods have their advantages. If you want full control, manual warm-up may be best.

If you want to save time and ensure inbox placement, automated tools can be a good choice. Whichever you pick, warming up is essential to get your emails where they belong—in the inbox.


Strategies to Increase Deliverability and Response Rates

Strategies to Increase Deliverability and Response Rates

1. Segment and Personalize Your Audience

Grouping your contacts by interests, demography, or needs is called “segmenting.” When you send emails that match people’s interests, they are more likely to respond.

Also, try using their name or mentioning something personal in the email. Personal touches make people feel valued, which leads to better response rates.

2. Clean Your Email List to Avoid Spam Folder

Over time, some email addresses in your list may become inactive or incorrect. Sending emails to inactive addresses can harm your sender reputation and make spam filters flag your messages.

Regularly clean your list to remove inactive emails. Many email service providers offer tools to help you do this automatically. By keeping your list updated, you avoid spam filters and improve email deliverability.

3. Optimize Email Timing and Frequency

Timing matters in email marketing. Sending too many emails can annoy people while sending too few can make them forget about you. Find the right balance by testing different sending frequencies.

Many studies suggest mid-mornings and mid-week days work best for personalized emails, but it’s smart to test what works for your audience. This way, your emails have a better chance of being seen and appreciated.


4. Authenticate Your Domain

Domain authentication proves to email providers that you are a trustworthy sender. Setting up authentication, such as SPF, DKIM, and DMARC, makes it less likely for your emails to end up in spam.

If this sounds technical, don’t worry—your email provider likely has a step-by-step guide on how to do it. This simple step strengthens your sender reputation and protects your domain.


5. Craft Compelling and Relevant Subject Lines

Your subject line is the first thing people see. If it’s interesting and relevant, they are more likely to open your email. Make sure your subject line is clear, direct, and not “spammy” by avoiding excessive punctuation or ALL CAPS.

Use words that reflect the content of your email to build trust. A good subject line can make the difference between a quick delete and a happy response.


Conclusion

Using an effective email warm-up process is essential for reaching the inbox and increasing response rates. Whether you’re sending cold emails or connecting with clients, strategies like segmenting your audience, cleaning your list, and using tools for email warm-up can make a big difference. When you instantly warm up your email account, you increase deliverability and build a positive sender reputation, helping your messages avoid the spam folder.
