Are you trying to clean up your contact database in your marketing automation platform? Email cleansing is a way to clean up your email list by removing unwanted contacts. You can then send emails that will be more likely to not only get to your contacts, but engage them. Sometimes customers use fake emails or accidentally mistype their email addresses, and this can lead to lower engagement for your emails and bring down the performance metrics of your email marketing. Email addresses can also get lost or changed over the years. Email cleansing can help you out by removing duplicate emails, nonexistent emails, old emails, and emails from contacts that unsubscribed or marked you as spam. It's very difficult and tedious to cleanse and verify your email list on your own, but don't worry - email cleansing tools are here to help clean and verify your email lists for you.

Why is Email Cleansing Important?

Popular email marketing platforms like Constant Contact, Mailchimp, Sendinblue, and Drip want to make sure companies that use their services aren't sending out spam mail to avoid violating anti-spam laws. When sending out mass emails, it's important that your email list contains real email addresses used by real people who opted to receive your content.

Emails that do not make it into your audiences’ inboxes because they're not real email addresses are called “bounces.” The more bounces you get, the higher your bounce rate. Having a lower bounce rate helps your overall sender score and improves your efficiency. Your sender score is your content reputation. If you have a good reputation, it helps your emails get through email provider filters, so your emails aren't flagged or blocked. You also don't want to waste time and money sending emails to incorrect addresses, and it will help make your analytics and reporting more accurate.
