Top 13 Email Warm Up Tools for 2023

  • January 3, 2023

More than 50% of emails sent globally are never seen by their intended recipients. Why? Because they never make it to the recipient’s primary inbox. Instead, they land somewhere in the spam folder where they stay collecting dust for decades to come.

If you don’t want this happening to your emails, you must warm up your domain before doing any cold outreach campaigns.

Let’s see why you need email warm up tools, what to look for when choosing one, and what are the best options waiting for you.

Let’s go!

Why Do You Need Email Warm Up Tools?

Email warm up tools, also known as email warming services, ensure that your emails don’t get blocked by spam filters. These tools work to establish a positive sender reputation with email platforms and build trust.

To do this, these tools send out a few emails daily to other domains in their network, who will then automatically reply. This helps email service providers (ESPs) to recognize your emails as legitimate and trust you as a sender.

Once you have achieved a good sender reputation and been whitelisted, your emails will be more likely to land in the primary inbox of your prospects and customers.

Other than this, email warm up tools also provide you with detailed reporting on all your warm up campaigns. This helps you to track the performance of your emails and make improvements as needed.

What to Look For in an Email Warm Up Tool?

Here are some features that a good email warm up tool must have:

1. Appropriate speed: You want a tool that warms up your domain quickly. At the same time, excessive speed can raise suspicion, so you want a tool that works at an appropriate speed.

2. Large network size: Larger networks make establishing a good sender reputation easier.

3. Excellent automation: Automated warming up will help streamline the process and save you time.

4. Detailed reporting: Look for a tool that provides detailed reports on your sender reputation and how the warming up process is going.

5. Good value for money: Many high-quality email warm up tools are affordable and come with free trials, so make sure not to overspend on one.

FAQs

What Is an Email Warm Up Tool?

An email warm up tool is a software designed to help you increase the deliverability of your emails by automating the email warmup process.

It works by sending out emails at a predetermined rate and monitoring your domain’s reputation to make sure it remains in good standing. This allows you to gradually introduce your domain to mailbox providers and build trust with them, which in turn increases the chances of your actual marketing emails landing in the primary inbox.

Does Email Warm Up Work?

Yes, email warm up works. It is a proven and tested technique that can help you increase the deliverability of your emails.

Why Do I Need to Warm Up My New Email Account?

Warming up your new email account is important as it allows mailbox providers to get familiar with your domain and trust it.

This increases the chances of your emails landing in the primary inbox, instead of being marked as spam or going into the junk folder. In turn, this can help you maximize open rates and engagement, and get better results from your campaigns.

Can I Send Cold Emails Without Warming up My Email Account?

Yes, you can send cold emails without warming up your email account but you shouldn’t.

Mailbox providers are very strict about the volume of emails you can send out from new domains. And if you don’t warm up your account, your emails will likely end up in the spam folder or get blocked altogether.
