Check email list validity is a great way to reach out and engage with your customers. But it only works if your email gets to the right people. That’s why check email list validity is so important. Invalid, inactive or fake emails are the reason for high bounce rates that damage your sender reputation and can even get you blacklisted.

The best way to avoid these issues is by performing pre-validation at the point of sign-up, for example by using a syntax check incorporated into your web forms. This will prevent a large percentage of the bad addresses from making it onto your lists in the first place. In addition, some email verification services will allow you to run a bulk validation of your existing email list, to remove bad addresses before they cause too many undeliverables. This can be a great sanity check before you start a new re-engagement campaign, or simply to help keep your lists healthy and clean over time.

Check Email List Validity: Ensuring Email List Accuracy and Deliverability

When choosing a tool to help with email list cleaning, it’s important to consider accuracy and speed. Many tools will guarantee bounce rates lower than 2% or 3% after they’ve cleaned your list. A fast turnaround is also helpful, especially if you’re working with a large list.

Some services offer more than just basic list checking, with some able to verify individual addresses one at a time, as well as provide a score for each address. This can be particularly useful for marketers who are working with smaller marketing lists, or who want to make sure their mailings are only going to valid recipients.
