Data enrichment and data cleansing are both important processes to keeping your data clean and getting the most out of your database. 

Without a clean and enriched database, you can’t segment emails, and you may end up wasting time and resources communicating with outdated or poorly aligned contacts. In a study by Deloitte, it was revealed that 71% of participants who were shown their own data said that it was only 0 to 50% accurate.

Data cleansing and data enrichment can help you turn your database into a powerful sales and marketing tool. In this post, we’ll explain:

  • The differences between data enrichment and data cleansing
  • How to apply these techniques for improved email marketing

What is data cleansing?

The goal of data cleansing is to make your contact database valid and accurate. Inaccurate data can lead to time wasted chasing contacts that aren’t relevant to your business, and can even jeopardize your email marketing as sending to too many incorrect email addresses can affect your sender reputation.

This is why data cleaning is an essential step for marketers. The process of data cleansing involves looking at the prospect or customer data you already have, correcting mistakes, and validating the information that’s there. It allows you to fix incorrect or misplaced data and spot any gaps.

The result is a database that’s consistent and predictable, with information in the correct fields.

The important thing is to ensure you have a good understanding of your data before you undertake data cleansing. Knowing how your fields are being used, how your data is collected and entered, and how the types of data relate to each other can help you resolve issues with duplicate fields and arbitrary entries.

What is data enrichment? 

Data enrichment is the process of adding external data from third-party data sources and adding it to your existing database. The goal is to get further insights from your data to improve your marketing or sales approach.

The data enrichment process improves on the data you already have. This process, sometimes referred to as ‘appending’, enables you to fill in gaps in your database, such as gender, company, age, and so on.

Data cleansing processes all take place within your existing database. It’s about fixing what’s already there, tidying it up, and optimizing it for use. Data enrichment is about looking at what’s in your database, finding the gaps, and adding information.

Both data cleansing and data enrichment processes are key to keeping a healthy database that will give you best results. First, ensure your data is accurate, then use data appending to enhance your contact list. The result? A far more powerful list to empower your sales and marketing teams.

How often should you clean and enrich your data?

Cleaning and enriching data are not one-off tasks. Data decays and becomes unusable, which means constant cleaning is important. Hopefully, you are collecting new contacts all the time, too, which means there is always new information to be added to your database.

Depending on your customer lifecycle, you could end up with a decay rate of almost 5% each month.

Data integrity should be a priority for sales and marketing teams, so you should clean and enrich your data throughout the year so that you’re armed with a healthy database. The frequency depends on a typical customer lifecycle, and how big your email database is.

Mistakes to avoid in data management

  1. Not cleansing your data regularly

As mentioned, committing to frequent data cleansing is important to ensure best results for your sales and marketing teams. Without regular data cleaning you could risk poor email metrics, a low email sender reputation, and time and resource wasted chasing uninterested or non-existent contacts.

  1. Siloing your data into various databases

Keeping data across multiple databases causes confusion, duplication, and makes it difficult for your sales and marketing teams to create clear and time-effective processes. Instead, consolidate your databases and use data management tools to merge and clean your data.

  1. Not having clear processes

Without a standard way of creating new contact records, or ways to update your databases, you can end up with inconsistent, duplicated, and even incorrect data. An example of this is when people want to add notes to a contact record, often they will create a new field. When this isn’t consistent, you can end up with your number of fields running into the hundreds, making it very difficult to manage.

Data enrichment vs data cleansing tools

When it comes to data enrichment and data cleansing, it can make sense to use a tool, rather than attempting it in-house. 

We’ve estimated that it takes a human about 3-5 minutes to clean one data point, meaning that it could take days or weeks to complete a data cleaning exercise depending on the size of your database.
