10 Warmy.io Alternatives to Boost Email Deliverability in 2024

Let me guess… You are here looking for Warmy.io alternatives because it costs you an arm and a leg to pay for the tool.

Undoubtedly, Warmy.io is a popular email warm-up tool, but with its high price tag, it’s only natural to look for more affordable options to build your sender reputation.

In this blog, we have mentioned the top 10 Warmy.io alternatives that offer similar or better features at a fraction of the cost.

Let’s get started!

Warmy.io- An Overview 

Warmy.io is an email warm-up tool that automatically warms up your emails using AI. It is the only tool that offers email warming in over 30 languages and allows you to add custom email warm-up templates seamlessly.

Moreover, Warmy has robust analytics features to visualize important statistics on a dashboard and present key data to users in the easiest way.

Why Should You Look for Warmy.io Alternatives? 

Like every coin has two sides, Warmy, despite being a great email warm-up tool, also has its own set of limitations that should not be overlooked when evaluating Warmy.io.

1. Cost vs. Benefit

If you are a small-scale business owner, then this can be one of the biggest drawbacks of choosing Warmy.io as an email warm-up tool. For every email account, you want to warm up, you need to pay an additional cost. 

For instance, if you are paying $20 to connect one email account for an email warm-up, you have to pay $20 again to connect another email account. Hence, the cost of using Warmy.io might outweigh the benefits. 

You will find other email warm-up tools like Trulyinbox that allow you to connect unlimited email accounts at a very low cost.

2. Technical Expertise Required

According to G2 and Capterra users, there is a learning curve that you need to go through while using Warmy.io. You will need to be a bit technically sound to set up your account, learn its features, and understand how the tool works.

3. Limited Customization

Warmy.io is an automated email warm-up tool; therefore, it offers limited customization features.

If you are looking for an email warm-up tool that offers advanced customization features, such as spam score analysis, domain blacklist checking, and segmentation capabilities, consider alternatives. 

These features enable you to tailor your warm-up process according to your strategy and achieve results that align with your business goals.

6 Tips to Improve Email Deliverability

Improved email deliverability is the key to successfully reaching your prospects’ inboxes! 

That was our list of top 10 warmy.io alternatives; however, you can do a few more things to improve your email deliverability.

Here are the 6 pro tips to boost your email deliverability so more of your cold outreach emails reach the inbox:

1. Use Secondary Domains for Cold Email Outreach 

If you send a lot of cold emails, don’t send them from your primary business domain. 

Sending high volumes can hurt your domain’s sender reputation, causing both cold outreach and important emails to land in the spam folder.

Instead, purchase several secondary domains strictly for cold email campaigns. 

For example, if your primary domain is acme.com, buy acme-sales.com, acmeoutreach.com, etc. Make sure the secondary domains resemble your primary ones.

2. Authenticate Your Secondary Domains

Before sending any emails, authenticate your secondary domains by setting up SPF, DKIM, and DMARC records. This proves to email service providers that you own and control the domain.

3. Gradually Ramp Up New Email Accounts 

When you start sending emails from a new account, email providers don’t know your sending reputation yet. So they’ll be extra cautious, increasing your chances of getting flagged as spam. 

The solution is to slowly ramp up new accounts, known as “warming up.” Start by sending just 15-20 emails per day in the first week. Then, increase your volume by 10-15% per week until you reach 50 emails per day. Tools like TrulyInbox can automate this process.

4. Verify Your Prospect List Before Sending 

Emailing fake or invalid addresses is one sure way to wreck your sender score. Always buy email lists from authentic and verified sources. Removing bad emails improves both deliverability and list health.

5. Send Relevant, Personalized Emails

Getting labeled as spam often boils down to sending irrelevant, generic content. Research prospects beforehand and craft emails that speak directly to their needs and avoid words to avoid spam filters. This shows recipients you took the time to understand them.

6. Monitor Deliverability Starting Day 1

Keep a close eye on key email stats like spam reports and inbox placement rates, starting from your first email campaign. If you notice particular emails underperforming, investigate why ASAP. Identifying issues early is much easier than recovering a damaged sending reputation.

By following these pro tips, your inbox placement rates will thank you!
