Email base hygiene, essentially, is the process of deleting emails that don't engage with your brand.

By cleaning your database, you start sending emails only to contacts who are truly potential customers and have an interest in your content. This is important for two distinct but equally relevant reasons:

  • Engage with warmed-up leads: The primary advantage is that you'll know exactly who the engaged leads are with your brand, and it'll become clearer at which stage of the buying journey they are – increasing the chance to convert them into customers.

  • Avoid deliverability issues: When you send emails that are not even opened or, if opened, recipients neither read nor click on the directing links, these emails end up looking like spam, even if they aren't.

Database hygiene is crucial for email deliverability and plays a fundamental role in the success of email marketing campaigns. It's an essential practice to ensure your campaigns reach the right audience, improve your sender reputation, and optimize the overall effectiveness of email communication strategies.

Eight tools that can help you

Several tools are available to aid in the contact database hygiene process. These tools are designed to check and validate email addresses, remove duplicate, inactive, or invalid contacts, and optimize the quality of your list. Here are some of them:

We've listed some tools that can assist in database hygiene, but there are others, both free and paid. It's worth researching them and experiencing their results.

Cleaning up your email database ensures reliability for your email marketing campaign, as you already know. So, before concluding the article, we've listed 2 more advantages of this practice:

  • Increased open and click-through rates

You'll have a list of contacts who, at the very least, are interested in consuming your content, even if they're not yet ready to buy the product or service; the interest has already been captured.

  • Reduced spam complaints

Spam, apart from not reaching the recipient's inbox, also attributes a poor reputation to the sending domain.

This is an issue that bothers many customers and is difficult to reverse. Therefore, it's essential to clean up the leads database to avoid losses and ensure that emails are sent to the inbox, maintaining a good image with providers.

Remember: the primary goal of email marketing is to establish and nurture relationships with leads. If these emails become mere spam blasts, this goal will never be achieved."
