Why Email Warmup Is Essential and How It Works
Email warmup plays a crucial role in improving deliverability, evading spam filters, and maintaining a higher sender reputation.
Imagine your sales team is sending out tons of emails, but they’re ending up in spam folders. For SMB founders, CEOs, and sales managers, this is a major roadblock to productivity. As per a report, 45% of all emails sent daily are spam. That's roughly 14.5 billion spam emails every day! No wonder ISPs are so strict about email warmup to protect users from unwanted messages.
Without email warmup, you’re fighting against deliverability issues, and with less than 0.1% of Gmail inboxes receiving spam, you need to take action. Proper email warmup services gradually build trust, allowing you to send up to 2,000 emails/day while boosting open rates.

In this blog, we’ll explore why email warmup is essential, how to get started, and the best email warmup tools for your team.
What is Email warmup?
Email warmup is the practice of sending a limited number of emails at first and then gradually increasing that number over time. It builds the sender's reputation with email service providers (ESPs).

You can accomplish email warmups by sending in small volumes, engaging with other emails (opening emails, replying, etc.), and gradually increasing volumes as your sender reputation improves.
Why Email warmup is Necessary?
Cold emails can be a game-changer for your business and sales strategy, but their success hinges on one critical factor: deliverability. Sending emails to the right inbox at the right time is essential, and that’s where email warmup comes into play. Without proper warmup, even the best-crafted emails can end up lost in the spam folder, costing you valuable leads and opportunities.
Reason for Gradually Increasing the Email Volume
Think of it like training for a marathon. You don't start by running 26 miles on day one. You build up your stamina gradually. Similarly, increase your email volume slowly to avoid triggering spam filters.

The primary reason for the gradual accumulation of email volumes is that ESPs can identify the sender as a legitimate, trusted source.
Building a Strong Sender Reputation
Maintaining a good reputation as a sender is critical for long-term success in email marketing. Consistent sender warmup practices help maintain a high sender reputation and consequently enable regular email delivery.

The email warmup process builds positive engagement and helps establish a reputation with ESPs and ISPs. If emails are sent too assertively or an account registered recently repeatedly marks them as spam, these actions might lead to IP block listing by ESPs.
This can ruin future email campaigns, making it impossible to reach your target audience.
Crucial for New Email Accounts and Domains
When creating brand new email accounts or domains, they can wrongly categorize them as spammers. If there is no proper warmup procedure, such newer installations may face significant issues with emails going through, thus blocking any communication from potential clients or business partners.
When you sign up for a new email account or create your own domain, ISPs (Internet service providers) do not recognize this account as a known sender. That's why sending so many emails initially triggers an unusual spam filter response.
Skipping the Spam Filters and Boosting Deliverability
One of the main advantages of email warmup is its ability to help you avoid spam filters. By gradually building trust with ISPs, you significantly reduce the chances of your emails ending in the spam folder.
This process ensures better email deliverability, crucial for businesses aiming to drive revenue through email marketing. According to a report by Campaign Monitor, email delivers an ROI of $42 for every $1 spent, but only when those emails reach their intended audience.
Better Engagement and Higher Open Rates
A warmed-up email account leads to better engagement. Open and reply rates naturally increase as your emails land inboxes rather than spam folders. HubSpot found that open rates for B2B emails hover around 21%, but with proper warmup, you can achieve even higher rates, leading to more meaningful conversations and sales.
Better Inbox Placement
The email warmup process ensures your messages land in inboxes rather than spam folders. By gradually increasing your email volume, ISPs recognize your sending behavior as trustworthy, improving inbox placement. With this gradual process, even well-designed email campaigns avoid being flagged as spam, harming your overall campaign success.
Consistency is critical to building trust with ISPs. A sudden surge in email volume raises red flags, triggering spam filters. Ultimately, email warmup aims to create a positive sender reputation, ensuring future emails reach your target audience's inboxes. This trust-building approach leads to higher open rates, better engagement, and more effective email marketing campaigns, positioning you for long-term success.
Readiness for Larger Campaigns
Once your email is adequately warmed up, you can confidently launch more extensive campaigns without risking your sender's reputation. This is crucial for businesses looking to scale their email marketing efforts. A well-warmed email account ensures that as you increase email volume, deliverability rates remain high, avoiding spam filters.
This process enables the smooth transition to higher volumes without compromising the success of growing businesses. With a strong sender reputation, you can scale effectively, focusing on crafting campaigns that engage your audience and drive results.

Common Email warmup Mistakes to Avoid
Warming up your email domain is crucial when it comes to cold emails. However, common mistakes—like aggressive ramp-up strategies and lack of engagement—can harm deliverability and lead to being blacklisted. All of these must be avoided to ensure the sender's reputation and, thus, a good run of the email marketing business.
Here are a few blunders that newbies make while starting their cold email marketing:
Sending too many emails too soon
You wouldn’t build a business overnight, so why would you expect to send 1,000 emails right out of the gate? The blunder people can make is by sending too many emails too soon. Which triggers spam filters, IP Blacklisting and damages your sender's reputation before you even get started.
Lack of Engagement
Just sending emails isn't enough—people need to engage with them. If no one opens or replies, it hurts your reputation. ISPs value regular, consistent behavior. Also, don't suddenly stop sending emails or increase your volume too quickly. ISPs value regular, consistent behavior.
Skipping Email Authentication
Without proper email authentication, ISPs may block your emails or send them straight to spam. Tools like SPF, DKIM, and DMARC help authenticate your emails, proving to ISPs that you're a legitimate sender. Skipping this step can harm your sender's reputation.
Make sure your email is authenticated before beginning the warmup process to avoid any deliverability issues.
Poor Email Content and Maintenance
High-quality, relevant content is essential to keep recipients engaged and maintain a positive sender reputation. No one likes boring emails! Regularly check your email performance reports to spot any potential issues before they affect your campaigns.
