Sending out emails to data that is incorrect can skew analytics, waste resources and just isn’t an effective use of time, energy and money. And if you are purchasing data at a cost averaging between $300 and $600 per thousand, you want to make sure you are paying for good quality data that you can use. This is where a sales tool such as data cleansing applications and email cleansing can really help.

What is Data Cleansing?


When the term data cleansing is used, it means to take a dataset of emails or other information and clean it up. This can be done manually, trying to find, correct and remove inaccurate records, but can also be done using clever tools.

In the context of email outreach, this process makes sure that your email lists are free from errors. This could be incorrect email addresses, duplicates or entries that aren’t formatted correctly.

It’s good practice to regularly check and cleanse your data to maintain its accuracy.

The Benefits of Data Cleansing Your Email Campaigns


Much like cleaning out a house or fridge, it can be really beneficial to clean your data regularly. This is for a number of reasons.

Improved Deliverability Rates

Regular data cleansing removes invalid email addresses that cause bounces. This improves your email deliverability rate and also means that if you are on a send budget each day, you’re not wasting time emailing incorrect information.

Enhanced Engagement

Clean data ensures that your emails reach the right people, increasing the likelihood of engagement through relevant content.

Cost Efficiency

Sending emails to non-existent or uninterested recipients is a drain on resources. Cleansing data helps in focusing efforts and budget on productive leads.

Better Analytics

And very importantly it improves the accuracy of your stats. Accurate data provides reliable insights. Clean data eliminates skewed analytics caused by outdated or incorrect information, leading to better campaign adjustments and strategies.

Challenges of Data Cleansing

Data cleansing does offer the best opportunity to use a database that is clean and up-to-date, but it does come with some drawbacks.

As databases expand, managing and cleansing large volumes of data becomes a harder task, and usually based on the size of the database as well. While all the tools above will help they are not infallible and some things will slip through the net sometimes.

Equally another issue is the sunken cost fallacy, where businesses may hesitate to discard or alter data they have invested time and money in obtaining. This reluctance can lead to hesitancy in removing outdated or incorrect data entries, potentially undermining the effectiveness of data cleansing efforts.

Data degradation is also a significant challenge even when you’re using a tool regarily. Email addresses and other types of data can quickly become obsolete, necessitating ongoing updates and verification to keep the database current and functional. This continuous need for data cleansing requires resources and can be labor-intensive. You can run the same database of emails through a tool one week to a next and get wildly different results.

Furthermore, the cost of implementing and maintaining data cleansing tools can be ongoing, particularly when you are dealing with a large database and pay-as-you-go pricing. Or an ongoing requirement that can stack up over the months.

And very importantly, data cleansing aside, if your targeting is wrong, or your copy is ineffective, then the entire operation is flawed from the outset. Below you’ll see a great video from HubSpot with some top tips on writing email marketing campaigns. 

When Data Cleansing Tools Are Used Correctly


If you are still unsure whether or not it’s worth investing in some data cleansing, take a look at this case study from ZeroBounce.

A company called MediaShares offered email campaigns for businesses looking for finance. The data however was outdated and with a bounce rate that regularly hit 12% their email provider canceled their service.

ZeroBounce was used to help clean the list which reduced the bounce rate to almost zero, it allowed them to regain access to their email client and continue their outreach for clients.

This is a great example of making sure that your database is up-to-date to prevent any issues arising.

Clean Data = Better Results

If your company is reliant on data to drive marketing and sales forward, data cleansing tools are a must. By regularly cleaning up email lists and other databases, businesses can enhance the efficiency and effectiveness of their campaigns. Improved deliverability rates, increased engagement, cost efficiency, and more reliable analytics are just some of the tangible benefits that come from maintaining clean data.

In addition to this, if you’re regularly reaching out to the wrong people, losing access to your mailer client and generally approaching in in a haphazard way, it can be an incredible drain on resources and your overall company reputation.

Cleaning data means that you are always working to the best practice all of the time when it comes to outreach.
