In this article, we will provide you with tips on how to address such issues and find the right resources to resolve them and find ways to create more efficient campaigns. 

Why Emails Go to Spam 

The question, “Why do emails go to spam in the first place?” should be the elephant in the room. It has several answers, with the main one being security reasons. There are countless fraudsters available online, and emails have been their favorite method for quite a while. Companies lose millions as a result of email fraud. 

For instance, in 2017, companies lost over 600 million US dollars to email-based fraud. It is one of the main reasons why emails go to spam. To protect their client's email service, providers have had to place extensive security measures to ensure their clients are safe. The spam feature is part of the security measures. 

Another breakthrough (for email companies at least) was the development of spam filters. If your email strategy is going to be successful, you need to understand how spam filters work and how to stop emails from going to spam.

Are Spam Filters the Reason Why My Emails Are Going to Spam?

Spam filters are the reason why your emails end up in the spam folder of your potential clients’ inboxes. As a result of the increase in email-related fraud, email service providers created automated spam filters that were meant to protect email users from fraudsters. These spam filters also have complicated ways to connect with potential clients. Initially, spam filters were pretty basic. They would just flag off emails with suspicious phrases and then move them to the spam folder. 

Of late, though, developers have improved these spam filters to make them more effective. The fact is, fraudsters managed to find out how to stop emails from going to junk. These developments, though, have hit hard on marketers, especially in terms of B2B online lead generation. You should understand how spam filters work if you do not want your emails to end up in the spam folder abyss.

How Do I Stop My Emails from Going to Spam?

Initially, spam filters were just picking up certain phrases or words and trying to detect them online. These tools have updated, though, and now use a more complex method to condemn emails to spam. The question you probably have is, “If these tools are so good, then how do I stop emails from going to spam?’’ Here are some factors that make your email end up on the dark side of the subscribers’ inboxes. 

Why Emails Are Spam-Filtered and How to Stop Emails from Going to Junk 

Several essential things deliver your emails right to the spam section, and you should make sure that you avoid them permanently so as not to spoil your company’s online reputation. Alternatively, you can hire an email marketing provider who takes care of the entire campaign and has the expertise to avoid being identified as a spammer.

Emailing People Without Prior Permission 

Emailing people at random without prior permission is the shortest way to the spam folder. It is an automatic condemnation worth transgression. The main reason why it is quite common is that marketers are now buying email lists. 

People in email lists would not have subscribed to your emails. The very moment your emails reach their inboxes, they go straight to spam. You might also need to know that besides being ineffective, sending emails without prior permission is illegal. It warrants a $16 000 fine per email, which is costly. 


The solution to this problem is quite simple. Do not buy email lists. Rather, build your email lists. Creating engaging content on your website is the best way to build great email lists. If you have a strong social media presence, make sure that you drive the traffic back to your website so that your audience can sign Opt-in forms

Your Opt-in form should clearly state that people are signing up for emails. Once you are done, you can send templated newsletters without having to worry about huge fines or the emails ending up in the spam folder. It is also essential that you look up the CAN-SPAM act. You do not want to end up on the wrong side of the law. 

Spam Trigger Words

Well, the reason why professionals discourage using automated email creation services is that they tend to use a lot of spam trigger words. Over the past years, email service providers have gathered a list of words that are most likely used by fraudsters. These words are very likely going to trigger spam filters if they are present in your email. 

It is essential to know which words are spam triggers. The most common ones include “special promotion,” “winner,” “risk-free,” “super popular,” and “for just $”. If you use these phrases in your campaigns, that’s the answer to the question, “Why are my emails going to spam?”


The cure for spam triggers condemning your emails to the abyss is quite simple — do not use spam triggers. Email service providers have a list of spam trigger words. Make sure you study it and avoid using them in your content if you want your emails to reach your recipients. 

Spam filters use several methods to qualify emails as inappropriate, but the easiest red flags you can avoid are spam trigger words. If you struggle with writing, though, you can always hire an email writing service. There are several types of agencies available on the market, and they offer tailored offers to ensure that you get a package that fits your business needs perfectly. 

Misleading Subject Line

This one is not only likely to get you blacklisted, but it can also get you in jail. Remember the CAN-SPAM act we mentioned before? Well, it is pretty clear when it comes to misleading subject lines. If you intentionally write a misleading subject line for your email and send it out to potential clients, you will transgress the law.  

Lines like “Urgent notice” without any data that requires urgency in the email count as misleading subject lines. Over the years, spam filters have evolved, but it is one thing they might not easily detect. If the reader notices the discrepancies, though, chances are they will banish all your future emails to the spam folder or open legal proceedings against you. If you were using this technique, then the “why my emails are going to spam” question is the least of your worries. 


For this problem, there is one ultimate solution. Just make sure your headlines are honest and address what is in the email. Unless you have millions of dollars to get you through the legal proceeding, do not be enticed into the world of email “clickbait.” If you struggle with writing powerful and incisive subject lines, you can always hire a service provider to do it for you.

Not Using a Business Domain 

A personal business domain is not only assigned business clout. A perfect signal that your business is legitimate is a trustworthy email address. It is quite rare for emails coming from a personalized domain to get to the spam folder. The reason for this is — people are more likely to open emails coming from a customized address than from a regular address. Such an approach will give you a great rating on the spam score


How do you fix this? It is simple, just get a personalized domain. There are dozens of services that offer great email domain services. It is a good investment, especially if you are planning to mainly use email-based marketing.

Keep in mind that the emails sent from a personalized email address tend to have a higher engagement rate than the generic ones, so they provide a more coherent path for communication. 

Using Spam-Linked Services

Some of the reasons why your emails are ending up as spam might not even be your fault, at least, directly. IP addresses that have been previously used to send out spam are usually recorded as a bad signal by spam filters. It means that emails sent directly from the same IP address are regarded as borderline spam. If you hire a marketing service that has previously sent out spam mail, your emails have a greater chance of being regarded as junk mail


The marketing industry is reputation-based, so if your server IP addresses get messed, it might cause trouble. To avoid getting your emails classified as spam as a result of the previous transgression by the marketing service provider, make sure you hire a legitimate provider. B2B lead generation provided by Belkins is a top-notch service that guarantees excellent results. 

To avoid being blacklisted by spam filters, companies like Belkins have strict regulations for clients. They help protect the reputation and, in the long run, maintain a clear record.

It is important to always remind your subscribers to activate this setting, especially when you start emailing them.
