Before we dive into the many email list cleaning services available, it’s important to understand why this step is so crucial to the effectiveness of your email marketing campaign. Validating the contacts on your email list prior to launching your campaign is a vital part of your overall marketing strategy.

In order to have a successful campaign that generates user engagement and new leads for your business, email deliverability must be kept top-of-mind. (Your email marketing campaign depends on it!)

If your email list contains bad addresses, spam traps, and other nasty roadblocks, you run the risk of damaging your sender reputation. One metric to watch is hard bounces, which is a signal you are hitting invalid emails.

If you don’t pay attention to where your emails are ending up, you can quickly run into trouble with your Internet Service Provider or ESP and get your domain blacklisted. Your goal is to reach the mailbox of your intended recipients, not trigger one of the many factors that negatively affect deliverability.

Why you need a list cleaning service

A profitable email list is one that can effectively reach your target audience. You need to be able to reach the inbox of your clients without hitting spam filters and hard bounces. An email list cleaning (also called verification, validation or email scrubbing) will remove invalid emails and ones that owned by known spam abuse complainers.

The key is to isolate the spam traps from your database you don’t send any of your email marketing messages to those addresses. Advanced tools including A.I. email scoring can be leveraged to better understand inbox activity of specific contacts.

Some of the terms you’ll see in the following list cleaning services include:

• Spam trap checker
• Social Append
• Email Bounce Checker
• IP Information Append
• Toxic Domain Checker
• Overview Reports
• MX Record Detection

• Email Typo Correction

This list was inspired from the features section of the ZeroBounce website, as its email list cleaning services are some of the most impressive and full-featured in the industry. (They even won an Affy Award for outstanding internet achievement for their email validation services.)

Some email verification and cleaning services can also enhance the quality of your database by filling in the missing pieces. It reads the data to accurately add contact details such as first and last name, gender, city and even IP address registration information.
