Top 10 Tools to Check Your Email IP & Domain Reputation

Domain Reputation Check Tools

Introduction

Email sender reputation is a vital factor that determines email deliverability. Since a solid reputation is crucial to ensure customer interaction, performing an email sender reputation check regularly as a part of a healthy email program has a significant effect on your deliverability and helps to identify trends over time.

Email sender reputation is a blend of IP and domain reputation. This article will briefly look at the differences between the two types, how email domain reputation is calculated, and go through the top 10 tools to check email IP and domain Reputation to assist you in finding the best one for your needs.

IP Reputation vs Domain Reputation

An email sender's reputation is essentially a score given by an Internet Service Provider (ISP). It assesses your email sending habits and analyzes whether you have adhered to the ISP's guidelines using complicated statistics that consider several reputations and govern how emails are delivered.

First, let's look at the two primary factors that affect sender reputation: IP reputation and domain reputation.

IP Reputation

An Email Service Provider (ESP) has a pool of IP addresses used to send emails. Although buying private IPs is a choice, most senders use IP addresses shared across a diverse group of sender accounts since it's expensive.

IP reputation is associated with the IP address used to send the email, which indicates whether email servers can accept emails sent from that specific address. If your IP address is a dedicated address, the IP reputation solely depends on how you use it. However, when you're using a shared IP, the behavior of all other senders who have the same IP impact your reputation. For example, some mailbox providers opt to blacklist you as well if they find a faulty mailing done by your shared IP.

IP reputation measures bounce rates, spam, and Unwanted Bulk Email (UBE) to determine the number of users who accept emails from a specific IP address. An important fact to remember is that IP reputations can be reset by changing the IP address of the domain.

Domain Reputation

Domain reputation defines the standing and ranking of your email sending domain by looking at past email sending patterns and the rate of interaction on the emails. Unlike IP reputation, Domain reputation is attached to the domain name and cannot be reset easily. Therefore, domain reputation is much more permanent than IP reputation.

There are three types of domains to consider when sending emails: From Address, Return-Path domain, and DomainKeys Identified Mail (DKIM) signing domain. Even though it's crucial to know which one of the above domains ISPs employ to verify domain reputation, it is affected by all three kinds of domains. As a result, maintaining a positive domain reputation necessitates careful control of all three domains.

How is Email Domain Reputation Calculated?

Recipients maintain records of each time a domain is used in an email and how that message appears inside the inbox to evaluate domain reputation. Most ISPs employ extensive algorithms to "rate" (on a scale of 0-100) a domain relying on the said information, then verify that score while processing future emails to create a level of reliability. The higher the domain reputation score at a specific recipient is, the more unlikely subsequent emails will be rejected or filtered as spam.

The sender domain's reputation is also linked to the IP reputation. So if your domain is renowned on the internet for delivering unwanted emails, using a reliable and effective IP via the finest ESPs won't work.

Top 10 Tools To Check Your Email Reputation

Now, let's go through some readily available tools that you can use to check your email server IP and domain reputation.

1) SenderScore.org

The Sender Score is similar to a credit score that assesses your reliability and evaluates the quality of your email program. It is a score between 0 and 100 that describes how mailbox providers perceive your IP address and identifies the strength of your sender reputation. The higher your score, the more reputable you are and the more likely your emails will be delivered. The calculations are based on a rotating 30-day average and show where your IP address stands compared to other IP addresses.

2) TrustedSource

The reputation data are obtained by monitoring McAfee's global security devices and hosted services in real-time.

3) BarracudaCentral
