Top 10 Email Warm-Up Tools – I Tried Them All!

As a founder of cold emailing software, I am constantly testing the latest email warm-up tools and their ability to increase email deliverability. 

This is because properly warmed-up emails are the backbone for having excellent cold email results.

As an insider in this industry, I understand how to test and what to look for in an email warm-up tool. 

My top factors while trying a warm-up service remain simple.

• It should help in reducing the email bounce rate
• It should prevent cold emails from landing in the spam
• It should align with ESPs and their new updates with best practices
• It should also offer a good setup to support email warm-ups in numbers when needed. 

After testing many tools throughout these years, I found that these tools have remained at the top of my list. Some are new, others are classic, but all are excellent for one reason: “warming up your emails.” 

Also, as I receive multiple suggestions and inputs from our clients and our data, I have insider tips that I share with my team and clients to take the most advantage of their email warm-up service provider. 

Don’t worry. I have also listed those tips here for you, so don’t forget to check them out!.

Top Email Warmup Tools Comparison

These are the top 5 tools that provide the best email warmup services. 

With this comparison, I aim to help you pick the right solution and increase your deliverability score.

I have also added the parameters to consider when buying an email warmup service!

Top 5 Benefits of Warming Up Your Inbox

The success of your cold email campaigns depends heavily on a properly warmed-up email account.

Why?

Here are some great reasons why you should warm up your email accounts:

1. Tracking, Maintaining, and Optimizing Deliverability
2. Tracking and Boosting Sender Reputation
3. Lower Bounce Rates
4. Track Inbox Placement Rates
5. Engages With Realistic Email Interactions

1. Tracking, Maintaining, and Optimizing Deliverability

The top benefit of using a warmup tool is to keep your email deliverability in check.

This includes maintaining regular email warm up processes, tracking, and, with that information, optimizing your email deliverability score. 

2. Tracking and Boosting Sender Reputation

When ISPs believe that your email is human-driven, your sender score remains solid.

A good sender reputation could then help land your emails in inboxes and save them from spam. This is directly related to achieving higher ROI from the efforts put into your cold outreach. 

3. Lower Bounce Rates

Keeping the bounce rate in check is critical. On average, keeping it between 2 and 5% is recommended.

Soft bounces are important to monitor, but sometimes, people forget to check even hard bounces, which can lower bounce rates and damage deliverability. 

Email warm-up can eliminate this risk by providing constant updates and tracking!

4. Track Inbox Placement Rates

This metric provides useful insights about how well your email reaches the prospect’s inboxes.

If your email warmup tool provides this insight (which the majority of them do), then your strategy-making will be much clearer in the future. 

5. Engages With Realistic Email Interactions

Advanced email warm-up algorithms use smart inboxes to create meaningful email exchanges.

These techniques mimic human-like interactions while marking your inboxes as “Not Spam.”

Altogether, this creates an even stronger sender reputation system.

Top 10 Email Warmup Tools

To keep this section crisp and valuable, I have created smaller segments in each tool to make it easier for you to read and understand. 

All of these tools are good, but they have some limitations (as expected), and I have tried to include them to help you make informed decisions.

Also, feel free to check out our video on the best email warmup tools:

1. TrulyInbox

Let’s start with 1st tool, TrulyInbox. 

Why TrulyInbox first? Here’s why!

They also have a vast and healthy pool of thousands of email accounts for email warming-up processes. 

And the most essential feature of an email warmup tool, mimicking human-like sending, here’s how Trulyinbox nails it. 

TrulyInbox sends emails in random time gaps according to the ESPs and uses multiple templates for doing this activity. All of this is automated. 

Amazing Add On: Unlike other email warm up tools, TrulyInbox allows you to fully customize your warm up process, too!

You can customize the frequency of sending as per your requirements. (We recommend gradual increments to safeguard your deliverability)

In the automated email warmup, time gaps can start from 50-150 seconds and go as high as 80-450 seconds (this is just an example from 1 template).

Email activity in this process is divided into actions like receiving, opening, replying, and re-opening emails.

5. Specific Features Needed

All the Email warmup tools come with a price. There are some tools that provide free versions, but they are also very limiting. So, deciding how much to spend is very crucial. 

Tip: If you are into cold emailing, try buying their yearly plans, as they are cheaper.

2. Ease of Use

While there are not many steps involved in warming up the emails, there are tools that have issues like glitches, lack of support, and too many technical hazards to be combpleted before it starts running. 

So, if you need frequent account linking of your team members or have less technical knowledge, consider using a tool with fewer complications. 

3. Integration With Existing Tools

Shifting data from 1 tool to another is not easy. Hence, check if your email warmup tool can be easily linked to your management tools or tools that you are going to use after warming up your emails. For example, integrate it with your cold email outreach tool.
