How to Warm Up an Email Domain – A Complete Blueprint
One of the first steps an email marketer should take is to warm up email domain.
This is a necessary start because mailbox providers are suspicious of new email domains sending messages to their users. They take strong measures to protect users from email spam, which makes it tough for new senders to reach the inbox.
A good email domain warmup process can help you avoid being flagged as spam and ensure your email deliverability rates are the best they can be.
Below we break down what the email domain warmup process is for and how to warm up a domain correctly. But first, here’s why we insist you adopt it.
Why Email Domain Warmup is Essential
Warming up a new email domain is not a fancy new email marketing trend; it’s critical.
It’s an important step directly impacting the success of different types of email campaigns. If you’re using a new domain or have been inactive for a while, skipping the warm-up phase can have huge consequences.
Mailbox providers view unwarmed domains as potential sources of spam; skipping email domain warm-up can:
- Significantly lower your inbox placement rates,
- Ruin your email sender reputation,
- Leave you with a failed investment.
Email domain warming is a strategic approach email senders use to establish a positive reputation with mail providers.
By learning how to warm up domain, you ensure your emails go to people’s inboxes, not spam. The main goal is to demonstrate to mailbox providers your email domain is legitimate, trustworthy, and not associated with spam email senders.
Warming up an email domain is the foundation of any email marketing effort; it helps ensure you get more emails into the primary inbox.
Now we get to a topic you’ve been waiting for: how to warm up an email domain!
How to Warm Up a Domain for Email Marketing
Many email service providers (ESPs) let you warm up email marketing operations but you can also do it yourself. The alternative is domain warmup tools, which cost money.
So what is email warm up and what does it require you to do?
You’ll need to:
- Gradually increase your sending volume,
- Segment your email list,
- Maintain a consistent sending schedule,
- Craft engaging email content to encourage recipient interactions,
- Be patient,
- Tune in every day to check if everything is going the way it should.
Below is a step-by-step guide on how to warm up domain for free.
Warm Up Email Domain for Free
If you’re strapped for cash, splurging on a domain warmup service may not be the best idea, especially when you can DIY it. Executing an email marketing warm up process is doable with some effort.
The free warm up email method is a practical approach, but warming up email domain without tools will require more time and effort.
Follow these 5 steps to warm up a domain for free.
1. Start Small With a Gradual Volume Increase
We recommend you start with around 100 contacts on day 1 and increase by approximately 10% per day. When you see positive interactions, slowly increase your sending volume. This kind of approach signals to ESPs you are a real sender who’s trying to warm up an email domain.
2. Divide your Email List into Segments Manually
A solid email segmentation strategy is critical here.
Divide your email list into segments based on engagement levels. Begin by sending emails to your most active and responsive email marketing subscribers; once you see positive feedback, gradually expand your outreach to those who engage less.
3. Stick to a Consistent Sending Schedule
Establish a regular sending schedule. Also, figure out the best time to send emails.
Consistency in email-sending patterns helps build trust with ESPs during the warm-up phase. You will need to show up and send those emails manually.
4. Engage With Relevant Content
Write and design relevant content that encourages recipients to interact with your emails. High engagement rates play a major role in improving your domain reputation.
5. Track and Adapt
Keep an eye on your email campaign metrics by tracking
And that’s how to warm up your email domain for free.
Free email warm-up methods work, but the paid ones can streamline the domain warm up process and get consistent results.
Although we understand the need for manual domain warm-up, we don’t recommend it. You won’t be able to detect every little issue that may arise, unlike specially designed software. So let’s check out paid warmup tools next.
Domain Warmup Tools
Domain warmup tools are paid software applications or services designed to automate and streamline the process of warming up domains.
They address the critical need to avoid spam filters and ensure your emails reach intended inboxes. An email warming service can help get your email marketing operation up and running.

How to Warm Up a New Email Domain
Did you just get your hands on a shiny new email domain?
For your email domain warm up, you should focus on actions that will help you establish trust with ESPs. You must also focus on the accuracy of your segmentation methods and email list hygiene.
There are different aspects of your email strategy to focus on, covered in the sections below.
Start Slow and Steady
Begin your warm-up process by gradually increasing your email volume. Start at 100 contacts and increase by approximately 10% per day. Sending a massive volume of emails right from the start can trigger spam filters. Begin with a small batch of emails and progressively work your way up.
Sort Your Email List
It helps to divide your email list into segments based on recipient engagement levels. Focus your initial emails on your most active and responsive subscribers. As you observe positive interactions, gradually expand your outreach to less engaged segments.
Focus on Content
Write interesting emails people want to click on and read. Relevant messages not only encourage clicks but also reduce the likelihood of recipients marking your messages as spam. Personalization and targeted content can boost your engagement rates.
Monitor Email Metrics
Regularly monitor email metrics. They will tell you if you’re doing everything right or not. If the overall engagement rate is low, you’ll need to make some adjustments.
Maintain Consistency
Look ahead and create an email content calendar to stick to. Sending emails at odd hours and overwhelming recipients one day, while stretching out the follow-up messages for too long would be wrong. Be clear and consistent, which will show mailbox providers you’re a trusted sender.
Be Flexible With the Daily Volume
It’s okay to reduce the sending volume per day if the metrics are trending in the wrong direction in terms of opens and clicks. You can increase it when the metrics start showing good results.
Identify the Emails That Are Performing Well
If possible, identify which emails are performing the best — email A/B testing can help. This will help you know what works and what doesn’t when you start a new campaign.
Be Ready to Stop if Needed
Sometimes, things won’t go as planned. And if the engagement drops and nothing changes, the best strategy is to stop sending emails. Instead, analyze your current email marketing strategy. This will help you later on when you start over.
How Long Does It Take to Warm Up Email Domain?
It’s important to set expectations before we discuss how to warm up email domain.
There is no fixed timeframe.
It depends on several factors:
- The age and the reputation of your domain,
- Your sending practices,
- The email engagement from your audience.
Brand-new domains with no prior email history typically need more time. You can start by sending a minimal volume of emails and gradually increasing the quantity as you track email engagement metrics. You may need a few weeks of warming up.
Established domains with a positive sending history often go through the warm-up phase more quickly. If your domain has maintained good engagement, it may only take a few weeks to prove your legitimacy to mail services.
Things to Avoid When Warming Up Your Email Domain
There are pitfalls you should avoid to ensure a smooth and effective process when warming up your email domain:
- Don’t rush: Sending a large volume of emails too quickly and too early can raise red flags; take your time.
- Avoid sending to cold lists: Avoid sending emails to inactive or outdated email lists during the initial warm-up phase.
- Don’t neglect segmentation: Failing to segment your email list properly can harm your warm-up process.
- Avoid inconsistent sending patterns: Inconsistency in your email sending schedule can confuse mail service providers. Stick to a consistent sending pattern.
- Don’t overlook content quality: Poorly written or irrelevant email content can lead to recipients marking your messages as spam.
- Avoid ignoring metrics: Neglecting to track email metrics is a mistake; they will give you all the insights you need for potential adjustments.
- Don’t share IP addresses with shady senders: Never share your IPs with bad senders. Ensure other senders sharing your IP space are clean and trustworthy.
- Avoid purchased email lists: Never buy email lists as a shortcut to building a subscriber base. These lists often contain outdated or unverified addresses.
- Don’t ignore feedback loops: Email service providers offer feedback loops that notify you of spam complaints.
- Don’t hide unsubscribe options: Always include a clear and visible one-click unsubscribe option in your emails.
How Domain Warmup Affects Email Deliverability
After successfully completing the warm-up phase for your email domain, you can expect significant positive changes in your email deliverability.
Here are the results you can expect if you do or don’t warm up your email domain properly:
| If you warm up your email domain ✅ | If you don’t warm up your email domain ❌ |
|---|---|
| Improved sender reputation | Poor sender reputation |
| Decreased bounce rates | High bounce rates |
| Higher engagement | Low engagement |
| Reduced spam complaints | Increased spam complaints |
ESPs view warm-up as a sign of trustworthiness, and a positive sender reputation built during this phase gives you higher engagement rates.
Warm Up Domain for Cold Email Marketing
Warming up your email domain is crucial for ensuring your cold email campaigns reach their intended recipients.
A gradual ramp-up builds a positive sender reputation with email providers, preventing your messages from landing in spam folders. This process ultimately increases your deliverability rates and maximizes the effectiveness of your outreach efforts.
How to Warm Up Your Domain for Cold Emails
Follow these 10 steps to warm up your email domain for cold email marketing:
- Set up essential authentication records: Ensure your domain has SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) records properly configured.
- Start with a small volume of emails: Begin by sending a very small number of emails daily, such as 10-20.
- Send emails to engaged contacts first: Initially, focus on sending emails to friends, family, colleagues, and opt-in email subscribers. Encourage them to reply to your emails, mark them as “not spam,” and add your email to a safe senders list.
- Utilize a warm-up service: Consider using a dedicated email warm-up service.
- Maintain consistent sending patterns: Avoid sudden spikes or drops in your email volume.
- Monitor your email deliverability: Regularly check your spam folder, use email deliverability tools, and use Google Postmaster Tools or similar services.

- Encourage replies and engagement: Prompt recipients to reply to your emails by asking questions or providing valuable information.
- Gradually introduce cold email campaigns: After a few weeks of consistent warm-up, start incorporating your cold email campaigns.
- Maintain good list hygiene: Regularly clean your email list by removing inactive or invalid email addresses.
