The Importance of Reputation in Email Marketing
As a business owner or marketer, you need to think about your sender reputation when sending marketing emails.

While you can put a lot of time and effort into creating the perfect email messages to send to your subscribers, if your sender score is low and the emails are landing straight in their spam folders, you will not be able to run a successful campaign.
Why You Should Check Email Address Reputation
Maybe you have been sending marketing emails, but are you getting results? Marketers will often spend a lot of time looking for different ways to optimise emails to improve open rates and click rates but overlook their email marketing sender reputation.
Your sender reputation or sender score refers to how much you are trusted by recipients. It is not always easy for marketers to build trust with their audience in general, but it can be impossible when lots of emails that you send are not even going to inboxes.
What is an Email Reputation?
Your email sender reputation is something that will be built over time. There are various factors that can have a negative impact on your sender score that you may not even be aware of.
Your sender reputation is directly linked to your email domain and is a record of how well or how poorly the emails that have been sent from your domain have performed. The good news is that it is possible to repair a bad email sender reputation, although it is not easy.
To keep your sender reputation high or recover it from a knock, you should focus on creating email marketing campaigns that include relevant content with the right message, sent at the right time, to the right audience.
What to Look For When You Check Email Reputation Online
It can sometimes be tricky to identify the factors that are causing your email sender reputation to drop. Some of the main factors to look out for that might influence your score include email list quality, email consistency, open rates, engagement, sending history, and the quality of the content.
Content mapping can help you improve your sender score as the prospect’s intent might be different based on the stage of the customer cycle that they are actively in. You can map the most relevant content to each buying cycle stage.
This allows you to speak more directly to each lead’s individual requirements or needs, which helps you make sure that you are having the right conversation with the right people, and at the right time.
Email Address Reputation Checker – What Affects Your Sender Score?
Email List Quality
The first thing to make sure when it comes to improving your sender reputation is that the contacts you are sending email messages to have the most accurate and up-to-date email addresses. If you are sending emails that are bouncing back because the email address is not spelt correctly or is no longer in use, this can have a negative impact on your sender’s reputation.
This is why it is so important to take the time to clean up your email list on a regular basis and remove any unengaged contacts and old, out-of-date data. This will ensure that you are only sending quality content to quality contacts, which will improve your sender reputation.
Sending History
Your IP address can play a major role in boosting the email reputation score and legitimacy of your emails. When your IP address has an established history, this can improve your email marketing sender score since it indicates that your sender, content, and recipients is legitimate.
This can be helpful to your credibility since spammers often change their IP addresses, making it almost impossible to obtain a reputable sending history with IPs.
Content Quality
Another major factor that can have an impact on your email marketing sender reputation is the quality of your content. If you are sending low-quality content, this can have a negative impact on your sender score.
Low-quality content could be an email that is filled with links, formatted poorly, overly promotional, or filled with spam trigger words. If this sounds like your content, then you’re almost guaranteed to be headed for spam folders.
Even if your emails do manage to make it through the spam filter, there’s a high chance that your prospects are going to mark the message as spam which will seriously damage your sender score.
Email Consistency
The volume of emails that you send and how consistently you are sending them is another factor that will have an impact on your email marketing sender reputation. Internet Service Providers and Mailbox providers will conduct analysis of sending patterns on a regular basis to determine if senders are following best practices or using spammy practices.
Engagement and Open Rates
Recently, mailbox providers have also been monitoring the way that subscribers are interacting with emails.
If it comes up that an email sent to a certain subscriber has low or no open or click-through rates, then they are going to begin filtering out these emails based on the user’s preferences. This can also have a negative impact on your email marketer sender score.
How to Check Email Domain Reputation
There are various third-party spam filtering and inbox delivery tools available that you can use to measure your email marketing sender reputation.
It’s important to consider deliverability when evaluating your sender score, which is your ability to successfully send emails that are delivered to inboxes rather than the spam folder. These third-party tools can be used to analyse your deliverability and give you an overall sender score.
They will review you as a sender, your content, and your domain to provide a breakdown of the percentage of your emails that are being delivered to inboxes versus those that are going to spam.
Many of these tools also offer handy features and advice that you can take advantage of to improve your email content to make it sound less spammy and more interesting and relevant to your readers.
How to Improve Your Email Domain Reputation Check
Ideally, open rates should be no lower than 18%. If your open rate is consistently below 10%, this is a sign that it is time to further explore different ways to improve engagement with your audience. It is also important to bear in mind that the average open rates may be different based on your industry, so it’s a good idea to become familiar with the email marketing benchmarks for your sector.
Check Email Reputation – How to Protect Your Sender Score
Since email marketing reputation is a factor that many will often overlook, being aware of the different factors that can influence your sender score already puts you ahead. To protect your sender score and increase your chance of sending emails that land in inboxes rather than spam boxes every time, keep these best practices in mind:
- Never send to purchased email lists, and make sure that you are only ever sending emails to subscribers who have given permission and opted into hearing from you. This will increase your email deliverability rate and reduce bounce rates.
- Clean your email list data on a regular basis and remove any email addresses that are out-of-date or misspelt from your list. It’s also a good idea to remove emails for any subscribers who are inactive or have not engaged with your content for a long time.
- Avoid appearing to spam your audience by controlling your sending frequency. You should create a send schedule and stick to it to reduce the chance of your emails being marked as spam.
- Segment your audience so that you can offer more relevant and targeted information to your subscribers. You are unlikely to get the best results from your email marketing campaigns and your sender reputation may suffer if the content you are sending is too vague.

Check My Mail Server Reputation: Dealing With Blacklists
When you check your sender reputation, you can also find out if your IP or domain has been added to a blacklist. In this case, you will need to go to the list in question and request to be delisted from the blacklist. If you are a legitimate sender and not a spammer, you will usually be removed in most cases.
Sometimes, you may get information on what you need to improve in order to ensure that your email or domain is not blacklisted again in future.
When sending marketing emails, it’s important to understand what your sender reputation is, what affects it, and how to maintain it.
