48.16% of all global emails are marked as junk emails, spam filters are more alert in 2022 than ever. 

The simple reason for emails landing in junk or spam is - Not warming up your email accounts adequately or not warming them at all. 

One non-negotiable for every email marketer is that their email campaigns land right in the prospect's inbox. But does this happen every single time? Not really. Have there been numerous cold email campaigns with a 100% deliverability rate? Definitely. 

In this blog, you’re going to find out the best email warm-up tools in 2022 to increase your chances of getting a 100% deliverability rate, maintaining a good sender reputation, as well as sliding into your email list’s inboxes smoothly.

What is warming up an email?

Email warming up is the process of establishing trust and a good sender reputation with your email service provider. Email service providers have serious rules and regulations when it comes to sending cold emails and they have strong spam filters. 

Without proper knowledge, email marketers stand a chance to lose this battle with email service providers. This is why email warm-up is so important. So what is warming up an email account exactly? It’s the process of sending emails gradually at a consistent pace to increase your email sending limit. 

Why do you have to send emails at a consistent pace in limited amounts? If the cold emails that you send from your email account precede the set limits by the email service provider, they trigger spam alerts and send your cold emails straight into the spam folder. Before sending cold emails to larger sets of email addresses it is necessary to be assured that you have done the initial part of warming up your email account in the correct way. 

An email account warm-up could be done manually or it could be automated. 

Maintaining a good sender reputation sends positive signals to your email service providers, more like unspoken permission to go ahead and send more emails in bigger quantities. By warming up your email account you are training the algorithm to trust you with larger campaigns. So generally what does an email warm-up tool do?

• It sends automated emails to email lists created specifically for warming-up purposes
• Then it opens those cold emails and reads them
• It responds to a specific percentage of cold emails to make it look natural
• If cold emails initially end up in spam it removes those cold emails from the spam folder
• The tool then goes one step further to mark some cold emails as Important

This email warm-up process is done by sending cold emails in specific numbers at a specific decided time by gradually increasing the number of emails per day to look professional and unsuspicious.

This email account warm-up process that simulates organic email activity assures email service providers to let their guard down and trust your email account.

Why do I need to warm up my new email account?

As email marketers, our primary goal is to reach our potential customer's inboxes. This is only possible with patience and the process of warming up your email account. Warming up the email accounts makes the sender look responsible and shows ESPs that the email sender or the organization adheres to the ESP’s rules.

Email warming up spikes your chances of reaching the inbox of your prospect. It increases email deliverability and improves the sender's reputation. This process clears the tag of a spam account from your organization. 

Warming up your email accounts helps you send cold emails to a maximum number of prospects increasing the potential of your cold email campaign. This is the best shot you get as an email marketer to look legit, achieve ideal delivery rates, and stay on the good side of email service providers. The process of email warming up reduces your chances of getting your email account suspended or even banned. 

Do I need to warm up an old email account too? 

The direct answer is Yes. 

Whether it’s an old account or a new one it is important to warm up your email account because this increases your sending limit. It prepares and trains your email account to send larger email campaigns to multiple datasets full of recipients. Using old email accounts is not a sure-shot way to reach your prospect’s inbox, in fact, the old accounts' inactivity may even look suspicious. So always warm up your old email accounts too.

Can You Warm Up Your Email Manually? 

Yes, you definitely can warm up your email account manually but it will take much longer than using automated email warm-up tools. You will be required to send multiple emails per day and reply to them consistently. The number of emails you send per day will increase and it definitely will take some time to reply to large sets of emails. 

You need to make sure that there is sufficient engagement in your cold email warm-up process. If there is no positive response or engagement or if you miss out because of any random reason, you risk losing your email account’s reputation. So while warming up your email account manually it is essential to keep your focus on positive engagement. 

Manual warming up of your email account requires a considerable amount of patience and time. If you don’t have both or you don’t have one from either of them. I suggest that you warm up your email account by using email warm-up tools, this way your warm-up process will get automated and you do not have to worry about negative results. You could save your time and focus on other things that matter and require more attention.

Manual vs automated email warm-up 

There are two ways to warm up your email account to increase the limit of emails per day - Manual warm-up and Automated warm-up.

You could be detail-oriented and warm up your email account manually but this process will take longer than automated email warm-up tools. The warming-up process also needs serious attention and consistency so while following the manual process it becomes important to not miss a single day or even miss the timing of your email warm-up campaigns. 

With automated warm-up tools, every cold email goes on time without breaking the whole process’s flow. While warming up your email account manually it is important to understand the basics as well as detailed aspects of the email warming process. Even a single mistake or a simple miscalculation could end up ruining your email account reputation. 

Automated email warm-up tools already have a system and process in place to run on autopilot which needs minimal to no assistance when it comes to the warming-up process once you’ve already set it up. Automated email warm-up tools help you save loads of time and the headache of keeping up with which email goes where, if you take emails out from spam, following up with multiple email addresses, etc.

When Can You Turn Off Your Email Warming Software? 

The honest answer to this question is - it depends. Different tools have various algorithms that have their own set of parameters and time to warm up email accounts. Generally, on average, it takes anywhere from 2 to 4 weeks to warm a normal email account. Most email warm-up tools have reports and health score features to check the reputation and the health of the account. When these reports show good and consistent numbers along with feedback that your account is ready is when you stop warming your account. 

The best way to figure out what works for you is to try the warming up process yourself and also use relevant knowledge of the past to make suitable changes and decisions. There is no one size fits all when it comes to email warm-up it always depends on the size of your email lists and the duration of your campaigns. If your email account is in good health it is much easier to warm it up. 

On the other hand, if your email account has a negative health score it will take time and patience to overturn this distrust into a good reputation in the eyes of email service providers. It is very important to get a health score check done even before you start your email warming activities. You must ensure that your account is not blacklisted. 

Having said that, ideally, it is normal for an email account to take 2- 4 weeks to warm up completely. When you take all these factors into consideration you will be able to make the correct decision with the help of data that you gather from these email warm-up tools.
