my emails are going to spam

You are probably wondering “Why are my emails going to SPAM? I am not a spammer.”. The truth is that the SPAM filters and system do not know your intentions, they can not understand the email completely, so they are relying solely on predefined algorithms, patterns and they observe specific things in your email. 


We will talk about the above-stated issue you may have and we will tell you how to resolve them. In order to be more descriptive, we decided to split this topic into two blog posts, so it is easier to read and process. In the first part, we will talk about the technical aspect and how to increase the chances your emails do not go to the SPAM folder. Let’s dive in!


Check your SPF, DKIM and RDNS records

The SPF record is a technique to protect your domain from spammers sending emails on behalf of it. Yes, this technique is not exactly related to your case, but having a properly configured SPF record gives a good sign to the receiving email servers and increases your credibility. 


If you want to get to know SPF in more detail, how to create such a record and verify it, you can check out our tutorial: What is an SPF record and how to create one?


DKIM (or DomainKeys Identified Mail) is a security standard. It is used to make sure that your emails are not modified in transit between the sending and receiving email servers.

If you want to know more about DKIM and how to set it up, check out our tutorial for DKIM.


The PTR record (also known as RDNS) is a specific type of DNS record where an IP address is pointing to a specific domain name (host name). We also prepared a detailed and technical explanation of what PTR is and how you can set it up.

All these records and configurations increase your email credibility and they are being checked whenever the receiving email server is processing your email. Being essential they set some basic security measures to protect your domain and emails.


Make sure your email server’s IP is not blacklisted

Another thing that the SPAM algorithms are checking is your email server IP address. To be more accurate, its reputation and whether it is present in the most popular blacklists. 

IP Email Blacklists are the lists with IP addresses/networks known for sending unwanted emails. If your IP address is in some blacklists, we suggest you try to delist it, because this will impact your email credibility. 

There are a few tools to check the reputation of your IP address. The one we prefer is MXToolBox: Mail blacklist checker


What about TLS encrypted emails?

Your emails are being sent thanks to the SMTP (Simple Mail Transfer Protocol) technology. This protocol, by design, is unencrypted. There is a thing called TLS (Transport Level Security) which can help you encrypt your messages so they can not be read from entities other than the person you are sending this email to. Check if your application (website, CMS, etc.) and email server support sending emails using TLS Authentication.


Do not use a free email address as your “From email”

We have seen this many times: You make an order in an online shop and you receive an email confirmation and in this email, the “from email” is:

This will not help you to build domain authority, and it does not look professional. 

If you have your own domain name, use it not only for your website but for your emails too. Check out the importance of custom business email and how to set up one?


Domain age and Domain reputation

Domain age and its reputation are very important factors because buying a domain name and starting to send SPAM immediately is done frequently. That’s what spammers usually do.

It is important to know that, just like in SEO, in the emails, there is a domain reputation too and it is crucial to protect it. 


The information we have shared with you is the essential foundation of your good domain email reputation. These techniques will increase the credibility of your emails and domain and will decrease the chance of your emails going to the SPAM folder.
