Traditional email marketing metrics such as bounce rate, click-through rate, open rate, and engagement rate are important for evaluating email marketing success, but there is another factor that is mostly overlooked but has a huge impact on email deliverability and email campaign success. What is that? That is email sender reputation. 

A good email sender reputation is necessary for the success of email campaigns. A good sender reputation increases the likelihood that your Email Service Provider (ESP) will land your email in the recipient’s primary inbox instead of the spam or junk folder. 

Before outlining the tools to check sender reputation, it is important to understand factors affecting the sender reputation score. Therefore, this article briefly explains factors affecting sender reputation and then discusses the top 7 tools to check sender reputation. 

Factors affecting email sender reputation

Two main factors influence sender reputation: IP reputation and domain reputation. What are these? Let’s explain them briefly. 

IP Reputation

Every device that is connected to the internet has an IP address—whether it is your computer or a server you used to send email in bulk. You must have seen numbers such as This is your IP address. Every email that you send has an IP address in its header that is invisible to the reader, but your ESP, such as Google and Yahoo, can monitor it to analyze your data and sending habits. Your ESP uses this analysis to rate your IP address, and it is called IP reputation. This IP address reputation score is high for legit senders while low for spammers. 

One can use both shared and dedicated IP addresses. If you are using a shared IP address, your reputation score is the result of sending habits of all the users using the same IP Address. You don’t have control over it. However, if you are using a dedicated IP address, then your reputation score is the result of your email sending habits. It is highly recommended for big businesses to use dedicated IP addresses to have more control over their email reputation. 

Domain reputation

In addition to IP addresses, every email is also associated with a domain name. For example, you are sending an email with the email id [email protected]. Here, xyz.com is your domain name. In addition to the IP address, your ESP also rates your domain reputation and assigns a score known as domain reputation. In contrast to IP reputation, your domain reputation is attached to your domain and is calculated based on your past email sending reputation. Therefore, it is difficult to reset your domain reputation.

Generally, there are three types of domains that affect domain reputation while sending emails. These three domains are From Address, Return-Path domain, and DomainKeys Identified Mail (DKIM) signing domain. To ensure a good domain reputation, it is imperative to control all these factors meticulously. 

So far, it has become evident that IP reputation and domain reputation that results in sender reputation plays an important role in email deliverability. Therefore, it is important to keep checking these reputations to ensure a good sender reputation.
